+Subject: [PATCH] OF: DT-Overlay configfs interface
+
+This is a port of Pantelis Antoniou's v3 port that makes use of the
+new upstreamed configfs support for binary attributes.
+
+Original commit message:
+
+Add a runtime interface to using configfs for generic device tree overlay
+usage. With it its possible to use device tree overlays without having
+to use a per-platform overlay manager.
+
+Please see Documentation/devicetree/configfs-overlays.txt for more info.
+
+Changes since v2:
+- Removed ifdef CONFIG_OF_OVERLAY (since for now it's required)
+- Created a documentation entry
+- Slight rewording in Kconfig
+
+Changes since v1:
+- of_resolve() -> of_resolve_phandles().

++Howto use the configfs overlay interface.
++
++A device-tree configfs entry is created in /config/device-tree/overlays
++and and it is manipulated using standard file system I/O.
++Note that this is a debug level interface, for use by developers and
++not necessarily something accessed by normal users due to the
++security implications of having direct access to the kernel's device tree.
++
++* To create an overlay you mkdir the directory:
++
++ # mkdir /config/device-tree/overlays/foo
++
++* Either you echo the overlay firmware file to the path property file.
++
++ # echo foo.dtbo >/config/device-tree/overlays/foo/path
++
++* Or you cat the contents of the overlay to the dtbo file
++
++ # cat foo.dtbo >/config/device-tree/overlays/foo/dtbo
++
++The overlay file will be applied, and devices will be created/destroyed
++as required.
++
++To remove it simply rmdir the directory.
++
++ # rmdir /config/device-tree/overlays/foo
++
++The rationalle of the dual interface (firmware & direct copy) is that each is
++better suited to different use patterns. The firmware interface is what's
++intended to be used by hardware managers in the kernel, while the copy interface
++make sense for developers (since it avoids problems with namespaces).

+Subject: [PATCH] Add arm64 configuration and device tree differences.
+ Disable MMC_BCM2835_SDHOST and MMC_BCM2835 since these drivers are crashing
+ at the moment.
+
+ARM64: Modify default config to get raspbian to boot (#1686)
+
+1. Enable emulation of deprecated instructions.
+2. Enable ARM 8.1 and 8.2 features which are not detected at runtime.
+3. Switch the default governer to powersave.
+4. Include the watchdog timer driver in the kernel image rather then a module.
+
+Tested with raspbian-jessie 2016-09-23.
+
+ARM64: Make it work again on 4.9 (#1790)
+
+* Invoke the dtc compiler with the same options used in arm mode.
+* ARM64 now uses the bcm2835 platform just like ARM32.
+* ARM64: Update bcmrpi3_defconfig
+
+Signed-off-by: Michael Zoran <mzoran@crowfest.net>
+
+Update arm64 Makefile to compile bcm2710 dtb file
+
+The line 'dtb-$(CONFIG_ARCH_BCM2835) += bcm2710-rpi-3-b.dtb' has been copied from previous rpi-4.14.y version into rpi-4.15.y arch/arm64/boot/dts/broadcom/Makefile to restore compilation of bcm2710-rpi-3-b.dtb device tree blob under 'make ARCH=arm64 dtbs' command.
+
+arm64: enable thermal / enable mmc (#2425)
+
+This commit adds support for RP3-B-Plus in in arch arm64 (#2464)
+
+Enable AES, AES bit slice, and AES NEON engines on arm64
+
+Enable bbr module for arm64

+Subject: [PATCH] ARM64/DWC_OTG: Port dwc_otg driver to ARM64
+
+In ARM64, the FIQ mechanism used by this driver is not current
+implemented. As a workaround, reqular IRQ is used instead
+of FIQ.
+
+In a separate change, the IRQ-CPU mapping is round robined
+on ARM64 to increase concurrency and allow multiple interrupts
+to be serviced at a time. This reduces the need for FIQ.
+
+Tests Run:
+
+This mechanism is most likely to break when multiple USB devices
+are attached at the same time. So the system was tested under
+stress.
+
+Devices:
+
+1. USB Speakers playing back a FLAC audio through VLC
+ at 96KHz.(Higher then typically, but supported on my speakers).
+
+2. sftp transferring large files through the buildin ethernet
+ connection which is connected through USB.
+
+3. Keyboard and mouse attached and being used.
+
+Although I do occasionally hear some glitches, the music seems to
+play quite well.

-Subject: [PATCH 098/806] ARM64/DWC_OTG: Port dwc_otg driver to ARM64
-
-In ARM64, the FIQ mechanism used by this driver is not current
-implemented. As a workaround, reqular IRQ is used instead
-of FIQ.
-
-In a separate change, the IRQ-CPU mapping is round robined
-on ARM64 to increase concurrency and allow multiple interrupts
-to be serviced at a time. This reduces the need for FIQ.
-
-Tests Run:
-
-This mechanism is most likely to break when multiple USB devices
-are attached at the same time. So the system was tested under
-stress.
-
-Devices:
-
-1. USB Speakers playing back a FLAC audio through VLC
- at 96KHz.(Higher then typically, but supported on my speakers).
-
-2. sftp transferring large files through the buildin ethernet
- connection which is connected through USB.
-
-3. Keyboard and mouse attached and being used.
-
-Although I do occasionally hear some glitches, the music seems to
-play quite well.

-
-IRQ-CPU mapping is round robined on ARM64 to increase
-concurrency and allow multiple interrupts to be serviced

+
+Uses the debugfs I/F to provide access to the AXI
+bus performance monitors.
+
+Requires the new mailbox peripheral access for access

+Subject: [PATCH] mcp2515: Use DT-supplied interrupt flags
+
+The MCP2515 datasheet clearly describes a level-triggered interrupt
+pin. Therefore the receiving interrupt controller must also be
+configured for level-triggered operation otherwise there is a danger
+of a missed interrupt condition blocking all subsequent interrupts.
+The ONESHOT flag ensures that the interrupt is masked until the
+threaded interrupt handler exits.
+
+Rather than change the flags globally (they must have worked for at
+least one user), allow the flags to be overridden from Device Tree
+in the event that the device has a DT node.
+
+See: https://github.com/raspberrypi/linux/issues/2175

+Subject: [PATCH] Tidy up of the ft5406 driver to use DT (#2189)
+
+Driver was using a fixed resolution, this commit
+adds touchscreen size, and coordinate flip and swap
+features via device tree overlays.
+
+Adds overrides so the VC4 can adjust the DT parameters
+appropriately; there is a newer version of the VC4 side
+driver that can now set up the appropriate DT values
+if required.

+Subject: [PATCH] ARM: Activate FIQs to avoid __irq_startup warnings
+
+There is a new test in __irq_startup that the IRQ is activated, which
+hasn't been the case for FIQs since they bypass some of the usual setup.
+
+Augment enable_fiq to include a call to irq_activate to avoid the
+warning.

-Subject: [PATCH 104/806] mcp2515: Use DT-supplied interrupt flags
-
-The MCP2515 datasheet clearly describes a level-triggered interrupt
-pin. Therefore the receiving interrupt controller must also be
-configured for level-triggered operation otherwise there is a danger
-of a missed interrupt condition blocking all subsequent interrupts.
-The ONESHOT flag ensures that the interrupt is masked until the
-threaded interrupt handler exits.
-
-Rather than change the flags globally (they must have worked for at
-least one user), allow the flags to be overridden from Device Tree
-in the event that the device has a DT node.
-
-See: https://github.com/raspberrypi/linux/issues/2175
- https://github.com/raspberrypi/linux/issues/2263

-Subject: [PATCH 105/806] Tidy up of the ft5406 driver to use DT (#2189)
-
-Driver was using a fixed resolution, this commit
-adds touchscreen size, and coordinate flip and swap
-features via device tree overlays.
-
-Adds overrides so the VC4 can adjust the DT parameters
-appropriately; there is a newer version of the VC4 side
-driver that can now set up the appropriate DT values
-if required.

-
-The VideoCore bootloader passes in Serial number and
-Revision number through Device Tree. Make these available to

-
-Mainline status:
-
-There is a commit in linux-next that standardize passing the serial
-number through Device Tree (string: /serial-number):
-ARM: 8355/1: arch: Show the serial number from devicetree in cpuinfo
-
-There was an attempt to do the same with the revision number, but it

-
-Augment enable_fiq to include a call to irq_activate to avoid the

+Subject: [PATCH] drm/vc4: Fix sending of page flip completion events
+ in FKMS mode.
+
+In the rewrite of vc4_crtc.c for fkms, I dropped the part of the
+CRTC's atomic flush handler that moved the completion event from the
+proposed atomic state change to the CRTC's current state. That meant
+that when full screen pageflipping happened (glxgears -fullscreen in
+X, compton, por weston), the app would end up blocked firever waiting
+to draw its next frame.

-Subject: [PATCH 114/806] drm/vc4: Fix sending of page flip completion events
- in FKMS mode.
-
-In the rewrite of vc4_crtc.c for fkms, I dropped the part of the
-CRTC's atomic flush handler that moved the completion event from the
-proposed atomic state change to the CRTC's current state. That meant
-that when full screen pageflipping happened (glxgears -fullscreen in
-X, compton, por weston), the app would end up blocked firever waiting
-to draw its next frame.

+Subject: [PATCH] i2c-gpio: Also set bus numbers from reg property
+
+I2C busses can be assigned specific bus numbers using aliases in
+Device Tree - string properties where the name is the alias and the
+value is the path to the node. The current DT parameter mechanism
+does not allow property names to be derived from a parameter value
+in any way, so it isn't possible to generate unique or matching
+aliases for nodes from an overlay that can generate multiple
+instances, e.g. i2c-gpio.
+
+Work around this limitation (at least temporarily) by allowing
+the i2c adapter number to be initialised from the "reg" property
+if present.

+Subject: [PATCH] irqchip: irq-bcm2835: Calc. FIQ_START at boot-time
+
+ad83c7cb2f37 ("irqchip/irq-bcm2836: Add support for DT interrupt polarity")
+changed the way that the BCM2836/7 local interrupts are mapped; instead
+of being pre-mapped they are now mapped on-demand. A side effect of this
+change is that the call to irq_of_parse_and_map from armctrl_of_init
+creates a new mapping, forming a gap between the IRQs and the FIQs. This
+ gap breaks the FIQ<->IRQ mapping which up to now has been done by assuming:
+
+1) that the value of FIQ_START is the same as the number of normal IRQs
+that will be mapped (still true), and
+
+2) that this value is also the offset between an IRQ and its equivalent
+FIQ (which is no longer the case).
+
+Remove both assumptions by measuring the interval between the last IRQ
+and the last FIQ, passing it as the parameter to init_FIQ().

-Subject: [PATCH 132/806] irqchip: irq-bcm2835: Calc. FIQ_START at boot-time
-
-ad83c7cb2f37 ("irqchip/irq-bcm2836: Add support for DT interrupt polarity")
-changed the way that the BCM2836/7 local interrupts are mapped; instead
-of being pre-mapped they are now mapped on-demand. A side effect of this
-change is that the call to irq_of_parse_and_map from armctrl_of_init
-creates a new mapping, forming a gap between the IRQs and the FIQs. This
- gap breaks the FIQ<->IRQ mapping which up to now has been done by assuming:
-
-1) that the value of FIQ_START is the same as the number of normal IRQs
-that will be mapped (still true), and
-
-2) that this value is also the offset between an IRQ and its equivalent
-FIQ (which is no longer the case).
-
-Remove both assumptions by measuring the interval between the last IRQ
-and the last FIQ, passing it as the parameter to init_FIQ().
-
-Fixes: https://github.com/raspberrypi/linux/issues/2432

++Kernel driver rpi-poe-fan
++=====================
++
++This driver enables the use of the Raspberry Pi PoE HAT fan.
++
++Author: Serge Schneider <serge@raspberrypi.org>
++
++Description
++-----------
++
++The driver implements a simple interface for driving the Raspberry Pi PoE
++(Power over Ethernet) HAT fan. The driver passes commands to the Raspberry Pi
++firmware through the mailbox property interface. The firmware then forwards
++the commands to the board over I2C on the ID_EEPROM pins. The driver exposes
++the fan to the user space through the hwmon sysfs interface.

-
-The published API to the dynamic overlay application mechanism now
-takes a Flattened Device Tree blob as input so that it can manage the
-lifetime of the unflattened tree. Conveniently, the new API call -
-of_overlay_fdt_apply - is virtually a drop-in replacement for
-create_overlay, which can now be deleted.

+Subject: [PATCH] bcm2835: interpolate audio delay
+
+It appears the GPU only sends us a message all 10ms to update
+the playback progress. Other than this, the playback position
+(what SNDRV_PCM_IOCTL_DELAY will return) is not updated at all.
+Userspace will see jitter up to 10ms in the audio position.
+
+Make this a bit nicer for userspace by interpolating the
+position using the CPU clock.
+
+I'm not sure if setting snd_pcm_runtime.delay is the right
+approach for this. Or if there is maybe an already existing
+mechanism for position interpolation in the ALSA core.
+
+I only set SNDRV_PCM_INFO_BATCH because this appears to remove
+at least one situation snd_pcm_runtime.delay is used, so I have
+to worry less in which place I have to update this field, or
+how it interacts with the rest of ALSA.
+
+In the future, it might be nice to use VC_AUDIO_MSG_TYPE_LATENCY.
+One problem is that it requires sending a videocore message, and
+waiting for a reply, which could make the implementation much
+harder due to locking and synchronization requirements.

+Subject: [PATCH] vchiq_2835_arm: Implement a DMA pool for small bulk
+ transfers (#2699)
+
+During a bulk transfer we request a DMA allocation to hold the
+scatter-gather list. Most of the time, this allocation is small
+(<< PAGE_SIZE), however it can be requested at a high enough frequency
+to cause fragmentation and/or stress the CMA allocator (think time
+spent in compaction here, or during allocations elsewhere).
+
+Implement a pool to serve up small DMA allocations, falling back
+to a coherent allocation if the request is greater than
+VCHIQ_DMA_POOL_SIZE.

-+=====================
-+
-+This driver enables the use of the Raspberry Pi PoE HAT fan.
-+
-+Author: Serge Schneider <serge@raspberrypi.org>
-+
-+Description
-+-----------
-+
-+The driver implements a simple interface for driving the Raspberry Pi PoE
-+(Power over Ethernet) HAT fan. The driver passes commands to the Raspberry Pi
-+firmware through the mailbox property interface. The firmware then forwards
-+the commands to the board over I2C on the ID_EEPROM pins. The driver exposes
-+the fan to the user space through the hwmon sysfs interface.

-Subject: [PATCH 140/806] bcm2835: interpolate audio delay
-
-It appears the GPU only sends us a message all 10ms to update
-the playback progress. Other than this, the playback position
-(what SNDRV_PCM_IOCTL_DELAY will return) is not updated at all.
-Userspace will see jitter up to 10ms in the audio position.
-
-Make this a bit nicer for userspace by interpolating the
-position using the CPU clock.
-
-I'm not sure if setting snd_pcm_runtime.delay is the right
-approach for this. Or if there is maybe an already existing
-mechanism for position interpolation in the ALSA core.
-
-I only set SNDRV_PCM_INFO_BATCH because this appears to remove
-at least one situation snd_pcm_runtime.delay is used, so I have
-to worry less in which place I have to update this field, or
-how it interacts with the rest of ALSA.
-
-In the future, it might be nice to use VC_AUDIO_MSG_TYPE_LATENCY.
-One problem is that it requires sending a videocore message, and
-waiting for a reply, which could make the implementation much
-harder due to locking and synchronization requirements.

-Subject: [PATCH 141/806] vchiq_2835_arm: Implement a DMA pool for small bulk
- transfers (#2699)
-
-During a bulk transfer we request a DMA allocation to hold the
-scatter-gather list. Most of the time, this allocation is small
-(<< PAGE_SIZE), however it can be requested at a high enough frequency
-to cause fragmentation and/or stress the CMA allocator (think time
-spent in compaction here, or during allocations elsewhere).
-
-Implement a pool to serve up small DMA allocations, falling back
-to a coherent allocation if the request is greater than
-VCHIQ_DMA_POOL_SIZE.

+Subject: [PATCH] drivers: thermal: step_wise: add support for
+ hysteresis
+
+From: Ram Chandrasekar <rkumbako@codeaurora.org>
+
+Step wise governor increases the mitigation level when the temperature
+goes above a threshold and will decrease the mitigation when the
+temperature falls below the threshold. If it were a case, where the
+temperature hovers around a threshold, the mitigation will be applied
+and removed at every iteration. This reaction to the temperature is
+inefficient for performance.
+
+The use of hysteresis temperature could avoid this ping-pong of
+mitigation by relaxing the mitigation to happen only when the
+temperature goes below this lower hysteresis value.

-Subject: [PATCH 161/806] spi: Make GPIO CSs honour the SPI_NO_CS flag
-
-The SPI configuration state includes an SPI_NO_CS flag that disables
-all CS line manipulation, for applications that want to manage their
-own chip selects. However, this flag is ignored by the GPIO CS code
-in the SPI framework.
-
-Correct this omission with a trivial patch.

+Subject: [PATCH] mmc/bcm2835-sdhost: Recover from MMC_SEND_EXT_CSD
+
+If the user issues an "mmc extcsd read", the SD controller receives
+what it thinks is a SEND_IF_COND command with an unexpected data block.
+The resulting operations leave the FSM stuck in READWAIT, a state which
+persists until the MMC framework resets the controller, by which point
+the root filesystem is likely to have been unmounted.
+
+A less heavyweight solution is to detect the condition and nudge the
+FSM by asserting the (self-clearing) FORCE_DATA_MODE bit.
+
+N.B. This workaround was essentially discovered by accident and without
+a full understanding the inner workings of the controller, so it is
+fortunate that the "fix" only modifies error paths.
+

- hysteresis
-
-From: Ram Chandrasekar <rkumbako@codeaurora.org>
-
-Step wise governor increases the mitigation level when the temperature
-goes above a threshold and will decrease the mitigation when the
-temperature falls below the threshold. If it were a case, where the
-temperature hovers around a threshold, the mitigation will be applied
-and removed at every iteration. This reaction to the temperature is
-inefficient for performance.
-
-The use of hysteresis temperature could avoid this ping-pong of
-mitigation by relaxing the mitigation to happen only when the
-temperature goes below this lower hysteresis value.

+Subject: [PATCH] media: tc358743: fix connected/active CSI-2 lane
+ reporting
+
+g_mbus_config was supposed to indicate all supported lane numbers, not
+only the number of those currently in active use. Since the TC358743
+can dynamically reduce the number of active lanes if the required
+bandwidth allows for it, report all lane numbers up to the connected
+number of lanes as supported in pdata mode.
+In device tree mode, do not report lane count and clock mode at all, as
+the receiver driver can determine these from the device tree.
+
+To allow communicating the number of currently active lanes, add a new
+bitfield to the v4l2_mbus_config flags. This is a temporary fix, to be
+used only until a better solution is found.

+Subject: [PATCH] media: tc358743: Check I2C succeeded during probe.
+
+The probe for the TC358743 reads the CHIPID register from
+the device and compares it to the expected value of 0.
+If the I2C request fails then that also returns 0, so
+the driver loads thinking that the device is there.
+
+Generally I2C communications are reliable so there is
+limited need to check the return value on every transfer,
+therefore only amend the one read during probe to check
+for I2C errors.

-Subject: [PATCH 179/806] mmc/bcm2835-sdhost: Recover from MMC_SEND_EXT_CSD
-
-If the user issues an "mmc extcsd read", the SD controller receives
-what it thinks is a SEND_IF_COND command with an unexpected data block.
-The resulting operations leave the FSM stuck in READWAIT, a state which
-persists until the MMC framework resets the controller, by which point
-the root filesystem is likely to have been unmounted.
-
-A less heavyweight solution is to detect the condition and nudge the
-FSM by asserting the (self-clearing) FORCE_DATA_MODE bit.
-
-N.B. This workaround was essentially discovered by accident and without
-a full understanding the inner workings of the controller, so it is
-fortunate that the "fix" only modifies error paths.

++Broadcom BCM283x Camera Interface (Unicam)
++------------------------------------------
++
++The Unicam block on BCM283x SoCs is the receiver for either
++CSI-2 or CCP2 data from image sensors or similar devices.
++
++The main platform using this SoC is the Raspberry Pi family of boards.
++On the Pi the VideoCore firmware can also control this hardware block,
++and driving it from two different processors will cause issues.
++To avoid this, the firmware checks the device tree configuration
++during boot. If it finds device tree nodes called csi0 or csi1 then
++it will stop the firmware accessing the block, and it can then
++safely be used via the device tree binding.
++
++Required properties:
++===================
++- compatible : must be "brcm,bcm2835-unicam".
++- reg : physical base address and length of the register sets for the
++ device.
++- interrupts : should contain the IRQ line for this Unicam instance.
++- clocks : list of clock specifiers, corresponding to entries in
++ clock-names property.
++- clock-names : must contain an "lp" entry, matching entries in the
++ clocks property.
++
++Unicam supports a single port node. It should contain one 'port' child node
++with child 'endpoint' node. Please refer to the bindings defined in
++Documentation/devicetree/bindings/media/video-interfaces.txt.
++
++Within the endpoint node the "remote-endpoint" and "data-lanes" properties
++are mandatory.
++Data lane reordering is not supported so the data lanes must be in order,
++starting at 1. The number of data lanes should represent the number of
++usable lanes for the hardware block. That may be limited by either the SoC or
++how the platform presents the interface, and the lower value must be used.
++
++Lane reordering is not supported on the clock lane either, so the optional
++property "clock-lane" will implicitly be <0>.
++Similarly lane inversion is not supported, therefore "lane-polarities" will
++implicitly be <0 0 0 0 0>.
++Neither of these values will be checked.
++
++Example:
++ csi1: csi1@7e801000 {
++ compatible = "brcm,bcm2835-unicam";
++ reg = <0x7e801000 0x800>,
++ <0x7e802004 0x4>;
++ interrupts = <2 7>;
++ clocks = <&clocks BCM2835_CLOCK_CAM1>;
++ clock-names = "lp";
++
++ port {
++ csi1_ep: endpoint {
++ remote-endpoint = <&tc358743_0>;
++ data-lanes = <1 2>;
++ };
++ };
++ };
++
++ i2c0: i2c@7e205000 {
++ tc358743: csi-hdmi-bridge@0f {
++ compatible = "toshiba,tc358743";
++ reg = <0x0f>;
++
++ clocks = <&tc358743_clk>;
++ clock-names = "refclk";
++
++ tc358743_clk: bridge-clk {
++ compatible = "fixed-clock";
++ #clock-cells = <0>;
++ clock-frequency = <27000000>;
++ };
++
++ port {
++ tc358743_0: endpoint {
++ remote-endpoint = <&csi1_ep>;
++ clock-lanes = <0>;
++ data-lanes = <1 2>;
++ clock-noncontinuous;
++ link-frequencies =
++ /bits/ 64 <297000000>;
++ };
++ };
++ };
++ };

++ *
++ * Based on TI am437x driver by Benoit Parrot and Lad, Prabhakar and
++ * TI CAL camera interface driver by Benoit Parrot.
++ *
++ *
++ * There are two camera drivers in the kernel for BCM283x - this one
++ * and bcm2835-camera (currently in staging).
++ *
++ * This driver directly controls the Unicam peripheral - there is no
++ * involvement with the VideoCore firmware. Unicam receives CSI-2 or
++ * CCP2 data and writes it into SDRAM. The only potential processing options are
++ * to repack Bayer data into an alternate format, and applying windowing.
++ * The repacking does not shift the data, so could repack V4L2_PIX_FMT_Sxxxx10P
++ * to V4L2_PIX_FMT_Sxxxx10, or V4L2_PIX_FMT_Sxxxx12P to V4L2_PIX_FMT_Sxxxx12,
++ * but not generically up to V4L2_PIX_FMT_Sxxxx16.
++ * Adding support for repacking and windowing may be added later.
++ *
++ * It should be possible to connect this driver to any sensor with a
++ * suitable output interface and V4L2 subdevice driver.
++ *
++ * bcm2835-camera uses the VideoCore firmware to control the sensor,
++ * Unicam, ISP, and all tuner control loops. Fully processed frames are
++ * delivered to the driver by the firmware. It only has sensor drivers
++ * for Omnivision OV5647, and Sony IMX219 sensors.
++ *
++ * The two drivers are mutually exclusive for the same Unicam instance.
++ * The VideoCore firmware checks the device tree configuration during boot.
++ * If it finds device tree nodes called csi0 or csi1 it will block the
++ * firmware from accessing the peripheral, and bcm2835-camera will
++ * not be able to stream data.

+Subject: [PATCH] media: adv7180: Nasty hack to allow input selection.
+
+Whilst the adv7180 driver support s_routing, nothing else
+does, and there is a missing lump of framework code to
+define the mapping from connectors on a board to the inputs
+they represent on the ADV7180.
+
+Add a nasty hack to take a module parameter that is passed in
+to s_routing on any call to G_STD, or S_STD (or subdev
+g_input_status call).

-Subject: [PATCH 183/806] overlays: uart0 - return GPIOs 14 and 15 to inputs
-
-In the event that alternate pins are used (only useful on Compute
-Modules), return the standard pins to inputs to avoid double-mapping
-them.

+Subject: [PATCH] arm: dt: Add DT overlays for ADV7282M, OV5647, and
+ TC358743
+
+DT overlays to setup the above devices via i2c_arm and csi1.
+(This currently does not use the i2c-mux-pinctrl driver to
+dynamically switch the pinctrl)
+
+tc358743 is tc358743 running at a default link frequency
+of 972Mbit/s. This allows up to 1080P50 UYVY on 2 lanes.
+There is a parameter to allow changing the link frequency,
+but the only values supported by the driver are 297000000
+for 594Mbit/s, and 486000000 for 972Mbit/s.
+There is also a parameter to enable 4 lane mode (only
+relevant to Compute Module (1 or 3) csi1).
+
+tc358743-audio overlay enables I2S audio from the TC358743
+to the Pi (SD to GPIO20, SCK to GPIO18, WFS to GPIO19).
+
+ADV7282M is the Analog Devices analogue video to CSI bridge
+chip.
+
+OV5647 is the Pi V1.3 camera module. Currently the driver only
+supports VGA 8bit Bayer and very few controls.

+Subject: [PATCH] dtoverlays: Add support for ADV7280-M, ADV7281-M and
+ ADV7281-MA chips.
+
+The driver that supports the ADV7282-M also supports the ADV7280-M,
+ADV7281-M, and ADV7281-MA.
+The 7280-M exposes 8 analogue inputs. The 7281-M doesn't have the
+I2P deinterlacing block. The 7281-MA has 8 inputs but no I2P.
+Otherwise they are the same as ADV7282-M.
+
+Adds a new overlay "adv728x" that includes the existing adv7282
+overlay but adds several parameters to modify the behaviour.
+
+Adds a new addr parameter to allow the I2C address to be changed.
+(the chip has an address select pin to change between 0x20 and 0x21).

-Subject: [PATCH 191/806] media: tc358743: fix connected/active CSI-2 lane
- reporting
-
-g_mbus_config was supposed to indicate all supported lane numbers, not
-only the number of those currently in active use. Since the TC358743
-can dynamically reduce the number of active lanes if the required
-bandwidth allows for it, report all lane numbers up to the connected
-number of lanes as supported in pdata mode.
-In device tree mode, do not report lane count and clock mode at all, as
-the receiver driver can determine these from the device tree.
-
-To allow communicating the number of currently active lanes, add a new
-bitfield to the v4l2_mbus_config flags. This is a temporary fix, to be
-used only until a better solution is found.

-Subject: [PATCH 193/806] media: tc358743: Check I2C succeeded during probe.
-
-The probe for the TC358743 reads the CHIPID register from
-the device and compares it to the expected value of 0.
-If the I2C request fails then that also returns 0, so
-the driver loads thinking that the device is there.
-
-Generally I2C communications are reliable so there is
-limited need to check the return value on every transfer,
-therefore only amend the one read during probe to check
-for I2C errors.

-+Broadcom BCM283x Camera Interface (Unicam)
-+------------------------------------------
-+
-+The Unicam block on BCM283x SoCs is the receiver for either
-+CSI-2 or CCP2 data from image sensors or similar devices.
-+
-+The main platform using this SoC is the Raspberry Pi family of boards.
-+On the Pi the VideoCore firmware can also control this hardware block,
-+and driving it from two different processors will cause issues.
-+To avoid this, the firmware checks the device tree configuration
-+during boot. If it finds device tree nodes called csi0 or csi1 then
-+it will stop the firmware accessing the block, and it can then
-+safely be used via the device tree binding.
-+
-+Required properties:
-+===================
-+- compatible : must be "brcm,bcm2835-unicam".
-+- reg : physical base address and length of the register sets for the
-+ device.
-+- interrupts : should contain the IRQ line for this Unicam instance.
-+- clocks : list of clock specifiers, corresponding to entries in
-+ clock-names property.
-+- clock-names : must contain an "lp" entry, matching entries in the
-+ clocks property.
-+
-+Unicam supports a single port node. It should contain one 'port' child node
-+with child 'endpoint' node. Please refer to the bindings defined in
-+Documentation/devicetree/bindings/media/video-interfaces.txt.
-+
-+Within the endpoint node the "remote-endpoint" and "data-lanes" properties
-+are mandatory.
-+Data lane reordering is not supported so the data lanes must be in order,
-+starting at 1. The number of data lanes should represent the number of
-+usable lanes for the hardware block. That may be limited by either the SoC or
-+how the platform presents the interface, and the lower value must be used.
-+
-+Lane reordering is not supported on the clock lane either, so the optional
-+property "clock-lane" will implicitly be <0>.
-+Similarly lane inversion is not supported, therefore "lane-polarities" will
-+implicitly be <0 0 0 0 0>.
-+Neither of these values will be checked.
-+
-+Example:
-+ csi1: csi1@7e801000 {
-+ compatible = "brcm,bcm2835-unicam";
-+ reg = <0x7e801000 0x800>,
-+ <0x7e802004 0x4>;
-+ interrupts = <2 7>;
-+ clocks = <&clocks BCM2835_CLOCK_CAM1>;
-+ clock-names = "lp";
-+
-+ port {
-+ csi1_ep: endpoint {
-+ remote-endpoint = <&tc358743_0>;
-+ data-lanes = <1 2>;
-+ };
-+ };
-+ };
-+
-+ i2c0: i2c@7e205000 {
-+ tc358743: csi-hdmi-bridge@0f {
-+ compatible = "toshiba,tc358743";
-+ reg = <0x0f>;
-+
-+ clocks = <&tc358743_clk>;
-+ clock-names = "refclk";
-+
-+ tc358743_clk: bridge-clk {
-+ compatible = "fixed-clock";
-+ #clock-cells = <0>;
-+ clock-frequency = <27000000>;
-+ };
-+
-+ port {
-+ tc358743_0: endpoint {
-+ remote-endpoint = <&csi1_ep>;
-+ clock-lanes = <0>;
-+ data-lanes = <1 2>;
-+ clock-noncontinuous;
-+ link-frequencies =
-+ /bits/ 64 <297000000>;
-+ };
-+ };
-+ };
-+ };

-+ * Copyright (C) 2017 - Raspberry Pi (Trading) Ltd.
-+ *
-+ * Dave Stevenson <dave.stevenson@raspberrypi.org>
-+ *
-+ * Based on TI am437x driver by Benoit Parrot and Lad, Prabhakar and
-+ * TI CAL camera interface driver by Benoit Parrot.
-+ *
-+ *
-+ * There are two camera drivers in the kernel for BCM283x - this one
-+ * and bcm2835-camera (currently in staging).
-+ *
-+ * This driver directly controls the Unicam peripheral - there is no
-+ * involvement with the VideoCore firmware. Unicam receives CSI-2 or
-+ * CCP2 data and writes it into SDRAM. The only potential processing options are
-+ * to repack Bayer data into an alternate format, and applying windowing.
-+ * The repacking does not shift the data, so could repack V4L2_PIX_FMT_Sxxxx10P
-+ * to V4L2_PIX_FMT_Sxxxx10, or V4L2_PIX_FMT_Sxxxx12P to V4L2_PIX_FMT_Sxxxx12,
-+ * but not generically up to V4L2_PIX_FMT_Sxxxx16.
-+ * Adding support for repacking and windowing may be added later.
-+ *
-+ * It should be possible to connect this driver to any sensor with a
-+ * suitable output interface and V4L2 subdevice driver.
-+ *
-+ * bcm2835-camera uses the VideoCore firmware to control the sensor,
-+ * Unicam, ISP, and all tuner control loops. Fully processed frames are
-+ * delivered to the driver by the firmware. It only has sensor drivers
-+ * for Omnivision OV5647, and Sony IMX219 sensors.
-+ *
-+ * The two drivers are mutually exclusive for the same Unicam instance.
-+ * The VideoCore firmware checks the device tree configuration during boot.
-+ * If it finds device tree nodes called csi0 or csi1 it will block the
-+ * firmware from accessing the peripheral, and bcm2835-camera will
-+ * not be able to stream data.

+Subject: [PATCH] net: lan78xx: Support auto-downshift to 100Mb/s
+
+Ethernet cables with faulty or missing pairs (specifically pairs C and
+D) allow auto-negotiation to 1000Mbs, but do not support the successful
+establishment of a link. Add a DT property, "microchip,downshift-after",
+to configure the number of auto-negotiation failures after which it
+falls back to 100Mbs. Valid values are 2, 3, 4, 5 and 0, where 0 means
+never downshift.

+Subject: [PATCH] BCM270X_DT: Add new Ethernet DT parameters
+
+Add "eth_downshift_after" DT parameter to allow the delay before the
+downshift to be specified. The default is 2 auto-negotiation cycles,
+and legal values are 2, 3, 4, 5 and 0 (disabled).
+
+Add "eth_max_speed" DT parameter as a way of prohibiting 1000Mbps
+links. This can be used to avoid the delay until the downshift mechanism
+activates. Legal values are 10, 100 and 1000, where the default is
+unlimited (effectively 1000Mbps).

-Subject: [PATCH 201/806] media: adv7180: Nasty hack to allow input selection.
-
-Whilst the adv7180 driver support s_routing, nothing else
-does, and there is a missing lump of framework code to
-define the mapping from connectors on a board to the inputs
-they represent on the ADV7180.
-
-Add a nasty hack to take a module parameter that is passed in
-to s_routing on any call to G_STD, or S_STD (or subdev
-g_input_status call).

+
+Create a semi-static mapping for the USB registers early in the boot
+process, before additional kernel threads are started, so all threads
+will have the mappings from the start. This avoids the need for

-From: Dave Stevenson <dave.stevenson@raspberrypi.org>
-Date: Wed, 31 Oct 2018 15:01:59 +0000
-Subject: [PATCH 204/806] arm: dt: Add DT overlays for ADV7282M, OV5647, and
- TC358743
-
-DT overlays to setup the above devices via i2c_arm and csi1.
-(This currently does not use the i2c-mux-pinctrl driver to
-dynamically switch the pinctrl)
-
-tc358743 is tc358743 running at a default link frequency
-of 972Mbit/s. This allows up to 1080P50 UYVY on 2 lanes.
-There is a parameter to allow changing the link frequency,
-but the only values supported by the driver are 297000000
-for 594Mbit/s, and 486000000 for 972Mbit/s.
-There is also a parameter to enable 4 lane mode (only
-relevant to Compute Module (1 or 3) csi1).
-
-tc358743-audio overlay enables I2S audio from the TC358743
-to the Pi (SD to GPIO20, SCK to GPIO18, WFS to GPIO19).
-
-ADV7282M is the Analog Devices analogue video to CSI bridge
-chip.
-
-OV5647 is the Pi V1.3 camera module. Currently the driver only
-supports VGA 8bit Bayer and very few controls.

-Subject: [PATCH 205/806] dtoverlays: Add support for ADV7280-M, ADV7281-M and
- ADV7281-MA chips.
-
-The driver that supports the ADV7282-M also supports the ADV7280-M,
-ADV7281-M, and ADV7281-MA.
-The 7280-M exposes 8 analogue inputs. The 7281-M doesn't have the
-I2P deinterlacing block. The 7281-MA has 8 inputs but no I2P.
-Otherwise they are the same as ADV7282-M.
-
-Adds a new overlay "adv728x" that includes the existing adv7282
-overlay but adds several parameters to modify the behaviour.
-
-Adds a new addr parameter to allow the I2C address to be changed.
-(the chip has an address select pin to change between 0x20 and 0x21).

+Subject: [PATCH] media: tc358743: Return an appropriate colorspace
+ from tc358743_set_fmt
+
+When calling tc358743_set_fmt, the code was calling tc358743_get_fmt
+to choose a valid format. However that sets the colorspace
+based on what was read back from the chip. When you set the format,
+then the driver would choose and program the colorspace based
+on the format code.
+
+The result was that if you called try or set format for UYVY
+when the current format was RGB3 then you would get told sRGB,
+and try RGB3 when current was UYVY and you would get told
+SMPTE170M.
+
+The value programmed into the chip is determined by this driver,
+therefore there is no need to read back the value. Return the
+colorspace based on the format set/tried instead.

-Ethernet cables with faulty or missing pairs (specifically pairs C and
-D) allow auto-negotiation to 1000Mbs, but do not support the successful
-establishment of a link. Add a DT property, "microchip,downshift-after",
-to configure the number of auto-negotiation failures after which it
-falls back to 100Mbs. Valid values are 2, 3, 4, 5 and 0, where 0 means

+
+The handling of loading platform drivers requires checking IS_ERR
+for the pointer on unload.
+If the driver fails to load, NULL the pointer during probe as
+platform_device_unregister already checks for NULL.

-Subject: [PATCH 223/806] dwc-otg: FIQ: Fix "bad mode in data abort handler"
-
-Create a semi-static mapping for the USB registers early in the boot
-process, before additional kernel threads are started, so all threads
-will have the mappings from the start. This avoids the need for
-data aborts to lazily update them.

-Subject: [PATCH 226/806] media: tc358743: Return an appropriate colorspace
- from tc358743_set_fmt
-
-When calling tc358743_set_fmt, the code was calling tc358743_get_fmt
-to choose a valid format. However that sets the colorspace
-based on what was read back from the chip. When you set the format,
-then the driver would choose and program the colorspace based
-on the format code.
-
-The result was that if you called try or set format for UYVY
-when the current format was RGB3 then you would get told sRGB,
-and try RGB3 when current was UYVY and you would get told
-SMPTE170M.
-
-The value programmed into the chip is determined by this driver,
-therefore there is no need to read back the value. Return the
-colorspace based on the format set/tried instead.

+Subject: [PATCH] staging: bcm2835-camera: Ensure timestamps never go
+ backwards.
+
+There is an awkward situation with H264 header bytes. Currently
+they are returned with a PTS of 0 because they aren't associated
+with a timestamped frame to encode. These are handled by either
+returning the timestamp of the last buffer to have been received,
+or in the case of the first buffer the timestamp taken at
+start_streaming.
+This results in a race where the current frame may have started
+before we take the start time, which results in the first encoded
+frame having an earlier timestamp than the header bytes.
+
+Ensure that we never return a negative delta to the user by checking
+against the previous timestamp.

+Clang warns:

+
+This is because mains_freq_qmenu is currently only used in an ARRAY_SIZE
+macro, which is a compile time evaluation in this case. Avoid this by
+adding mains_freq_qmenu as the imenu member of this structure, which
+matches all other controls that uses the ARRAY_SIZE macro in v4l2_ctrls.
+This turns out to be a no-op because V4L2_CID_MPEG_VIDEO_BITRATE_MODE is
+defined as a MMAL_CONTROL_TYPE_STD_MENU, which does not pass the imenu
+definition along to v4l2_ctrl_new in bm2835_mmal_init_controls.

- a sensible timestamp
-
-H264 header come from VC with 0 timestamps, which means they get a
-strange timestamp when processed with VC/kernel start times,
-particularly if used with the inline header option.
-Remember the last frame timestamp and use that if set, or otherwise
-use the kernel start time.

+Controls of type MMAL_CONTROL_TYPE_STD_MENU call v4l2_ctrl_new_std_menu
+with a max value and a mask. The max value is one of the defined
+values for the control, however in the config array there are several

+Subject: [PATCH] staging: bcm2835-camera: Correct
+ V4L2_CID_COLORFX_CBCR behaviour
+
+With V4L2_CID_COLORFX_CBCR calling ctrl_set_colfx it was incorrectly
+assigning the colour values to the enable field of dev->colourfx
+instead of the u and v fields.
+
+Correct the assignments.
+
+Reported as a Coverity issue
+Detected by CoverityScan CID#1419711 ("Unused value")

+From e7723c6bcf31a440b8762e9e22497ff3fbbb7056 Mon Sep 17 00:00:00 2001
+From: Dave Stevenson <dave.stevenson@raspberrypi.org>
+Date: Mon, 24 Sep 2018 16:30:37 +0100
+Subject: [PATCH] staging: vc04_services: Split vchiq-mmal into a
+ module
+
+In preparation for adding a video codec V4L2 module which also
+wants to use vchiq-mmal functions, split it out into an
+independent module.
+The minimum number of changes have been made to achieve this
+(eg straight moves where possible) so existing checkpatch
+errors will still be present.
+

+The timeout period for VPU communications is a useful thing

+ passing parameters
+
+The callback from vchi_mmal to the client was growing lots of extra
+parameters. Consolidate them into a single struct instead of
+growing the list further.
+The struct is associated with the client buffer, therefore there
+are various changes to setup various containers for the struct,
+and pass the appropriate members.

+From: Dave Stevenson <dave.stevenson@raspberrypi.org>
+Date: Mon, 24 Sep 2018 18:15:38 +0100
+Subject: [PATCH] staging: mmal-vchiq: Add support for event callbacks.
+
+(Preparation for the codec driver).
+The codec uses the event mechanism to report things such as
+resolution changes. It is signalled by the cmd field of the buffer
+being non-zero.
+
+Add support for passing this information out to the client.

+Subject: [PATCH] staging: vc04_services: Add new vc-sm-cma driver
+
+This new driver allows contiguous memory blocks to be imported
+into the VideoCore VPU memory map, and manages the lifetime of
+those objects, only releasing the source dmabuf once the VPU has
+confirmed it has finished with it.

-Subject: [PATCH 253/806] staging: bcm2835-camera: Ensure timestamps never go
- backwards.
-
-There is an awkward situation with H264 header bytes. Currently
-they are returned with a PTS of 0 because they aren't associated
-with a timestamped frame to encode. These are handled by either
-returning the timestamp of the last buffer to have been received,
-or in the case of the first buffer the timestamp taken at
-start_streaming.
-This results in a race where the current frame may have started
-before we take the start time, which results in the first encoded
-frame having an earlier timestamp than the header bytes.
-
-Ensure that we never return a negative delta to the user by checking
-against the previous timestamp.

-Clang warns:
-
-drivers/staging/vc04_services/bcm2835-camera/controls.c:59:18: warning:
-variable 'mains_freq_qmenu' is not needed and will not be emitted
-[-Wunneeded-internal-declaration]

-1 warning generated.
-
-This is because mains_freq_qmenu is currently only used in an ARRAY_SIZE
-macro, which is a compile time evaluation in this case. Avoid this by
-adding mains_freq_qmenu as the imenu member of this structure, which
-matches all other controls that uses the ARRAY_SIZE macro in v4l2_ctrls.
-This turns out to be a no-op because V4L2_CID_MPEG_VIDEO_BITRATE_MODE is
-defined as a MMAL_CONTROL_TYPE_STD_MENU, which does not pass the imenu
-definition along to v4l2_ctrl_new in bm2835_mmal_init_controls.

++1) Convert to be a platform driver.
++
++Right now when the module probes, it tries to initialize VCHI and
++errors out if it wasn't ready yet. If bcm2835-v4l2 was built in, then
++VCHI generally isn't ready because it depends on both the firmware and
++mailbox drivers having already loaded.
++
++We should have VCHI create a platform device once it's initialized,
++and have this driver bind to it, so that we automatically load the
++v4l2 module after VCHI loads.
++
++2) Support SELECTION API to define crop region on the image for encode.
++
++Particularly for resolutions that aren't a multiple of the macroblock
++size, the codec will report a resolution that is a multiple of the macroblock
++size (it has to have the memory to decode into), and then a different crop
++region within that buffer.
++The most common example is 1080P, where the buffer will be 1920x1088 with a
++crop region of 1920x1080.
++
++3) Refactor so that the component creation is only on queue_setup, not open.
++
++Fixes v4l2-compliance failure on trying to open 100 instances of the
++device.

+RGB3/BGR3 end up being 3 bytes per pixel, which meant that

+That doesn't work, so switch to an arithmetic alignment for

+Subject: [PATCH] media: vb2: Allow reqbufs(0) with "in use" MMAP
+ buffers
+
+Videobuf2 presently does not allow VIDIOC_REQBUFS to destroy outstanding
+buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are
+considered "in use". This is different behavior than for other memory
+types and prevents us from deallocating buffers in following two cases:
+
+1) There are outstanding mmap()ed views on the buffer. However even if
+ we put the buffer in reqbufs(0), there will be remaining references,
+ due to vma .open/close() adjusting vb2 buffer refcount appropriately.
+ This means that the buffer will be in fact freed only when the last
+ mmap()ed view is unmapped.
+
+2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer
+ is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF
+ get and decremented on DMABUF release. This means that the buffer
+ will be alive until all importers release it.
+
+Considering both cases above, there does not seem to be any need to
+prevent reqbufs(0) operation, because buffer lifetime is already
+properly managed by both mmap() and DMABUF code paths. Let's remove it
+and allow userspace freeing the queue (and potentially allocating a new
+one) even though old buffers might be still in processing.

+
+commit 2f7d8dbb11287cbe9da6380ca14ed5d38c9ed91f upstream.
+
+While having SECURITYFS enabled for the tpm subsystem is beneficial in
+most cases, it is not strictly necessary to have it enabled at all.
+Especially on platforms without any boot firmware integration of the TPM
+(e.g. raspberry pi) it does not add any value for the tpm subsystem,
+as there is no eventlog present.
+
+By turning it from 'select' to 'imply' it still gets selected per
+default, but enables users who want to save some kb of ram by turning
+SECURITYFS off.

+Issues have been observed in LibreElec as this was unconditionally

+enable it.
+
+Includes a partial revert of 2147700eb7a1b9e55e0684f0749114ce35d61571

-Subject: [PATCH 264/806] staging: vc04_services: Split vchiq-mmal into a
- module
-
-In preparation for adding a video codec V4L2 module which also
-wants to use vchiq-mmal functions, split it out into an
-independent module.
-The minimum number of changes have been made to achieve this
-(eg straight moves where possible) so existing checkpatch
-errors will still be present.

+-Overlays are loaded using the "dtoverlay" directive. As an example, consider
+-the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the
+-pre-DT world this would be loaded from /etc/modules, with an explicit
+-"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled,
+-this becomes a line in config.txt:
+-
+- dtoverlay=lirc-rpi
+-
+-This causes the file /boot/overlays/lirc-rpi.dtbo to be loaded. By
+-default it will use GPIOs 17 (out) and 18 (in), but this can be modified using
+-DT parameters:
+-
+- dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13
+-
+-Parameters always have default values, although in some cases (e.g. "w1-gpio")
+-it is necessary to provided multiple overlays in order to get the desired
+-behaviour. See the list of overlays below for a description of the parameters
++Overlays are loaded using the "dtoverlay" config.txt setting. As an example,
++consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded
++by writing a magic string comprising a device identifier and an I2C address to
++a special file in /sys/class/i2c-adapter, having first loaded the driver for
++the I2C interface and the RTC device - something like this:
++
++ modprobe i2c-bcm2835
++ modprobe rtc-ds1307
++ echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device

++default it usees address 0x68, but this can be modified with an additional DT
++parameter:
++
++ dtoverlay=i2c-rtc,ds1307,addr=0x68

+
+When handling for V4L2_CID_MPEG_VIDEO_REPEAT_SEQ_HEADER was added
+the firmware would reject the setting if H264 hadn't already been
+selected. This was fixed in the firmware at that point, but to
+enable backwards compatibility the returned error was ignored.
+
+That was Dec 2013, so the chances of having a firmware that still

+Subject: [PATCH] gpio-ir: change default pull configuration to up
+
+IR receivers like the TSOP series from Vishay and compatible ones
+have active-low open collector outputs with an internal pull up of
+about 30k (according to the TSOP datasheets).
+
+Activating a pull-down resistor on the GPIO will make it work against
+the pull-up in the IR receiver and brings the idle input voltage down
+to about 1.9V (measured on a RPi3B+ with a TSOP4438). While that's
+usually enough to make the RPi see a high signal it's certainly not
+optimal and may even fail when using an IR receiver with a weaker pull-up.
+
+Switching the default GPIO pull to "up" results in an input voltage
+level of about 3.3V and ensures that an idle state (high signal) will
+be detected if no IR receiver is attached.

-Subject: [PATCH 268/806] staging: mmal-vchiq: Make a mmal_buf struct for
- passing parameters
-
-The callback from vchi_mmal to the client was growing lots of extra
-parameters. Consolidate them into a single struct instead of
-growing the list further.
-The struct is associated with the client buffer, therefore there
-are various changes to setup various containers for the struct,
-and pass the appropriate members.

-(Preparation for the codec driver).
-The codec uses the event mechanism to report things such as
-resolution changes. It is signalled by the cmd field of the buffer

+Subject: [PATCH] lan78xx: Debounce link events to minimize poll storm
+
+The bInterval is set to 4 (i.e. 8 microframes => 1ms) and the only bit
+that the driver pays attention to is "link was reset". If there's a
+flapping status bit in that endpoint data, (such as if PHY negotiation
+needs a few tries to get a stable link) then polling at a slower rate
+would act as a de-bounce.
+
+See: https://github.com/raspberrypi/linux/issues/2447

+Subject: [PATCH] ASoC: Add support for AudioSense-Pi add-on soundcard
+
+AudioSense-Pi is a RPi HAT based on a TI's TLV320AIC32x4 stereo codec
+
+This hardware provides multiple audio I/O capabilities to the RPi.
+The codec connects to the RPi's SoC through the I2S Bus.
+
+The following devices can be connected through a 3.5mm jack
+ 1. Line-In: Plain old audio in from mobile phones, PCs, etc.,
+ 2. Mic-In: Connect a microphone
+ 3. Line-Out: Connect the output to a speaker
+ 4. Headphones: Connect a Headphone w or w/o microphones
+
+Multiple Inputs:
+ It supports the following combinations
+ 1. Two stereo Line-Inputs and a microphone
+ 2. One stereo Line-Input and two microphones
+ 3. Two stereo Line-Inputs, a microphone and
+ one mono line-input (with h/w hack)
+ 4. One stereo Line-Input, two microphones and
+ one mono line-input (with h/w hack)
+
+Multiple Outputs:
+ Audio output can be routed to the headphones or
+ speakers (with additional hardware)

-Date: Tue, 25 Sep 2018 14:53:49 +0100
-Subject: [PATCH 276/806] staging: vc04_services: Add a V4L2 M2M codec driver
-
-This adds a V4L2 memory to memory device that wraps the MMAL
-video decode and video_encode components for H264 and MJPEG encode
-and decode, MPEG4, H263, and VP8 decode (and MPEG2 decode
-if the appropriate licence has been purchased).

-+1) Convert to be a platform driver.
-+
-+Right now when the module probes, it tries to initialize VCHI and
-+errors out if it wasn't ready yet. If bcm2835-v4l2 was built in, then
-+VCHI generally isn't ready because it depends on both the firmware and
-+mailbox drivers having already loaded.
-+
-+We should have VCHI create a platform device once it's initialized,
-+and have this driver bind to it, so that we automatically load the
-+v4l2 module after VCHI loads.
-+
-+2) Support SELECTION API to define crop region on the image for encode.
-+
-+Particularly for resolutions that aren't a multiple of the macroblock
-+size, the codec will report a resolution that is a multiple of the macroblock
-+size (it has to have the memory to decode into), and then a different crop
-+region within that buffer.
-+The most common example is 1080P, where the buffer will be 1920x1088 with a
-+crop region of 1920x1080.
-+
-+3) Refactor so that the component creation is only on queue_setup, not open.
-+
-+Fixes v4l2-compliance failure on trying to open 100 instances of the
-+device.

+ single-TT hubs
+
+See https://github.com/raspberrypi/linux/issues/2734
+
+The "Hub Port" field in the split transaction packet was always set
+to 1 for single-TT hubs. The majority of single-TT hub products
+apparently ignore this field and broadcast to all downstream enabled
+ports, which masked the issue. A subset of hub devices apparently
+need the port number to be exact or split transactions will fail.

+Subject: [PATCH] pwm: Send a uevent on the pwmchip device upon channel
+ sysfs (un)export
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 552c02e3e7cfe2744b59de285aaea70021ae95c9 upstream.
+
+This patch sends a uevent (KOBJ_CHANGE) on the pwmchipN device,
+everytime a pwmX channel has been exported/unexported via sysfs. This
+allows udev to implement rules on such events, like:
+
+SUBSYSTEM=="pwm*", PROGRAM="/bin/sh -c '\
+ chown -R root:gpio /sys/class/pwm && chmod -R 770 /sys/class/pwm;\
+ chown -R root:gpio
+/sys/devices/platform/soc/*.pwm/pwm/pwmchip* && chmod -R 770
+/sys/devices/platform/soc/*.pwm/pwm/pwmchip*\
+'"
+
+This is a replacement patch for commit 7e5d1fd75c3d ("pwm: Set class for
+exported channels in sysfs"), see [1].
+
+basic testing:
+$ udevadm monitor --environment &
+$ echo 0 > /sys/class/pwm/pwmchip0/export
+KERNEL[197.321736] change /devices/.../pwm/pwmchip0 (pwm)
+ACTION=change
+DEVPATH=/devices/.../pwm/pwmchip0
+EXPORT=pwm0
+SEQNUM=2045

-Subject: [PATCH 282/806] media: vb2: Allow reqbufs(0) with "in use" MMAP
- buffers
-
-Videobuf2 presently does not allow VIDIOC_REQBUFS to destroy outstanding
-buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are
-considered "in use". This is different behavior than for other memory
-types and prevents us from deallocating buffers in following two cases:
-
-1) There are outstanding mmap()ed views on the buffer. However even if
- we put the buffer in reqbufs(0), there will be remaining references,
- due to vma .open/close() adjusting vb2 buffer refcount appropriately.
- This means that the buffer will be in fact freed only when the last
- mmap()ed view is unmapped.
-
-2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer
- is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF
- get and decremented on DMABUF release. This means that the buffer
- will be alive until all importers release it.
-
-Considering both cases above, there does not seem to be any need to
-prevent reqbufs(0) operation, because buffer lifetime is already
-properly managed by both mmap() and DMABUF code paths. Let's remove it
-and allow userspace freeing the queue (and potentially allocating a new
-one) even though old buffers might be still in processing.

-
-commit 2f7d8dbb11287cbe9da6380ca14ed5d38c9ed91f upstream.
-
-While having SECURITYFS enabled for the tpm subsystem is beneficial in
-most cases, it is not strictly necessary to have it enabled at all.
-Especially on platforms without any boot firmware integration of the TPM
-(e.g. raspberry pi) it does not add any value for the tpm subsystem,
-as there is no eventlog present.
-
-By turning it from 'select' to 'imply' it still gets selected per
-default, but enables users who want to save some kb of ram by turning
-SECURITYFS off.

-Subject: [PATCH 286/806] Revert "staging: vchiq_arm: Register a platform
- device for the audio driver"
-
-This reverts commit ab59590ed562b89db51fe46cee5db96b9bc5abd8.
-
-Issues have been observed in LibreElec as this was unconditionally
-loading the audio driver instead of having the DT parameter to
-enable it.
-
-Includes a partial revert of 2147700eb7a1b9e55e0684f0749114ce35d61571
-which fixed up the error handling.

+
+Fixes a v4l2-compliance failure when passed a buffer that is
+too small.
+queue_setup wasn't handling the case where !(*nplanes), as
+used from CREATE_BUFS and requiring the driver to sanity
+check the provided buffer parameters. It was assuming that
+it was always being used in the REQBUFS case where it provides
+the buffer properties.

+Subject: [PATCH] char: vc_mem: Fix up compat ioctls for 64bit kernel
+
+compat_ioctl wasn't defined, so 32bit user/64bit kernel
+always failed.
+VC_MEM_IOC_MEM_PHYS_ADDR was defined with parameter size
+unsigned long, so the ioctl cmd changes between sizes.

-When handling for V4L2_CID_MPEG_VIDEO_REPEAT_SEQ_HEADER was added
-the firmware would reject the setting if H264 hadn't already been
-selected. This was fixed in the firmware at that point, but to
-enable backwards compatibility the returned error was ignored.
-
-That was Dec 2013, so the chances of having a firmware that still

-Subject: [PATCH 291/806] gpio-ir: change default pull configuration to up
-
-IR receivers like the TSOP series from Vishay and compatible ones
-have active-low open collector outputs with an internal pull up of
-about 30k (according to the TSOP datasheets).
-
-Activating a pull-down resistor on the GPIO will make it work against
-the pull-up in the IR receiver and brings the idle input voltage down
-to about 1.9V (measured on a RPi3B+ with a TSOP4438). While that's
-usually enough to make the RPi see a high signal it's certainly not
-optimal and may even fail when using an IR receiver with a weaker pull-up.
-
-Switching the default GPIO pull to "up" results in an input voltage
-level of about 3.3V and ensures that an idle state (high signal) will
-be detected if no IR receiver is attached.

+
+All calls to the gpio library are in contexts that can sleep,

+by controllers which require sleeping (eg I2C GPIO expanders).
+
+Switch to using gpiod_set_value_cansleep instead of gpiod_set_value

+
+Add the ability to interpret the high bits of the dreq specifier as
+flags to be included in the DMA_CS register. The motivation for this
+change is the ability to set the DISDEBUG flag for SD card transfers
+to avoid corruption when using the VPU debugger.

-Subject: [PATCH 304/806] dwc_otg: fix bug with port_addr assignment for
- single-TT hubs
-
-See https://github.com/raspberrypi/linux/issues/2734
-
-The "Hub Port" field in the split transaction packet was always set
-to 1 for single-TT hubs. The majority of single-TT hub products
-apparently ignore this field and broadcast to all downstream enabled
-ports, which masked the issue. A subset of hub devices apparently
-need the port number to be exact or split transactions will fail.

+Subject: [PATCH] ASoC: pcm512x: Implement the digital_mute interface
+
+[ Upstream commit 3500f1c589e92e0b6b1f8d31b4084fbde08d49cb ]
+
+Clicks and pops of various volumes can be produced while the device is
+opened, closed, put into and taken out of standby, or reconfigured.
+Fix this, by implementing the digital_mute interface, so that the
+output is muted during such operations.

+ pcm512x_digital_mute()
+
+[ Upstream commit 28b698b7342c7d5300cfe217cd77ff7d2a55e03d ]
+
+We accidentally call mutex_unlock(&pcm512x->mutex); twice in a row.
+
+I re-wrote the error handling to use "goto unlock;" instead of returning
+directly. Hopefully, it makes the code a little simpler.

-Subject: [PATCH 307/806] pwm: Send a uevent on the pwmchip device upon channel
- sysfs (un)export
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-commit 552c02e3e7cfe2744b59de285aaea70021ae95c9 upstream.
-
-This patch sends a uevent (KOBJ_CHANGE) on the pwmchipN device,
-everytime a pwmX channel has been exported/unexported via sysfs. This
-allows udev to implement rules on such events, like:
-
-SUBSYSTEM=="pwm*", PROGRAM="/bin/sh -c '\
- chown -R root:gpio /sys/class/pwm && chmod -R 770 /sys/class/pwm;\
- chown -R root:gpio
-/sys/devices/platform/soc/*.pwm/pwm/pwmchip* && chmod -R 770
-/sys/devices/platform/soc/*.pwm/pwm/pwmchip*\
-'"
-
-This is a replacement patch for commit 7e5d1fd75c3d ("pwm: Set class for
-exported channels in sysfs"), see [1].
-
-basic testing:
-$ udevadm monitor --environment &
-$ echo 0 > /sys/class/pwm/pwmchip0/export
-KERNEL[197.321736] change /devices/.../pwm/pwmchip0 (pwm)
-ACTION=change
-DEVPATH=/devices/.../pwm/pwmchip0
-EXPORT=pwm0

+Subject: [PATCH] usb: dwc_otg: Use dma allocation for mphi dummy_send
+ buffer
+
+The FIQ driver used a kzalloc'ed buffer for dummy_send,
+passing a kernel virtual address to the hardware block.
+The buffer is only ever used for a dummy read, so it
+should be harmless, but there is the chance that it will
+cause exceptions.
+
+Use a dma allocation so that we have a genuine bus address,
+and read from that.
+Free the allocation when done for good measure.

+Subject: [PATCH] staging: vc-sm-cma: Use a void* pointer as the handle
+ within the kernel
+
+The driver was using an unsigned int as the handle to the outside world,
+and doing a nasty cast to the struct dmabuf when handed it back.
+This breaks badly with a 64 bit kernel where the pointer doesn't fit
+in an unsigned int.
+
+Switch to using a void* within the kernel. Reality is that it is
+a struct dma_buf*, but advertising it as such to other drivers seems
+to encourage the use of it as such, and I'm not sure on the implications
+of that.

- kernel
-
-The MMAL client_component field is used with the event
-mechanism to allow the client to identify the component for
-which the event is generated.
-The field is only 32bits in size, therefore we can't use a
-pointer to the component in a 64 bit kernel.
-
-Component handles are already held in an array per VCHI
-instance, so use the array index as the client_component handle
-to avoid having to create a new IDR for this purpose.

-compat_ioctl wasn't defined, so 32bit user/64bit kernel

-VC_MEM_IOC_MEM_PHYS_ADDR was defined with parameter size

+Subject: [PATCH] staging: mmal-vchiq: Always return the param size
+ from param_get
+
+mmal-vchiq is a reimplementation of the userland library for MMAL.
+When getting a parameter, the client provides the storage and
+the size of the storage. The VPU then returns the size of the
+parameter that it wished to return, and as much as possible of
+that parameter is returned to the client.
+
+The implementation previously only returned the size provided
+by the VPU should it exceed the buffer size. So for parameters
+such as the supported encodings list the client had no idea
+how much of the provided storage had been populated.

-Subject: [PATCH 322/806] dtoverlays: Correct DT handling camera GPIOs
-
-The firmware has support for updating overrides with the correct
-GPIO settings for the camera GPIOs, but the wrong device tree
-setup ended up being merged.
-Correct the DT configuration so that the firmware does set it
-up correctly.

+Subject: [PATCH] staging: bcm2835_codec: Add support for the ISP as an
+ M2M device
+
+The MMAL ISP component can also use this same V4L2 wrapper to
+provide a M2M format conversion and resizer.
+Instantiate 3 V4L2 devices now, one for each of decode, encode,
+and isp.
+The ISP currently doesn't expose any controls via V4L2, but this
+can be extended in the future.

-Subject: [PATCH 323/806] media: ov5647: Use gpiod_set_value_cansleep
-
-All calls to the gpio library are in contexts that can sleep,
-therefore there is no issue with having those GPIOs controlled
-by controllers which require sleeping (eg I2C GPIO expanders).
-
-Switch to using gpiod_set_value_cansleep instead of gpiod_set_value
-to avoid triggering the warning in gpiolib should the GPIO
-controller need to sleep.

-
-The driver was powering on the source subdevice as part of STREAMON,
-and powering it off in STREAMOFF. This isn't so great if there is a
-significant amount of setup required for your device.
-
-Copy the approach taken in the Atmel ISC driver where s_power(1) is called
-on first file handle open, and s_power(0) is called on the last release.

+ VB2_MEMORY_DMABUF buffers
+
+If the queue is configured as VB2_MEMORY_DMABUF then vb2_core_expbuf
+fails as it ensures the queue is defined as VB2_MEMORY_MMAP.
+
+Correct the handling so that we unmap the buffer from vcsm and the
+VPU on cleanup, and then correctly get the dma buf of the new buffer.

+
+We don't use the same async update path between fkms and normal kms,

+ configuration.
+
+When handler of data_available interrupt is fired, queue_work ends up
+getting called and it can block on a spin lock which is not allowed in
+interrupt context. The fix was to run the handler from a thread context

+Subject: [PATCH] video: bcm2708_fb: Try allocating on the ARM and
+ passing to VPU
+
+Currently the VPU allocates the contiguous buffer for the
+framebuffer.
+Try an alternate path first where we use dma_alloc_coherent
+and pass the buffer to the VPU. Should the VPU firmware not
+support that path, then free the buffer and revert to the
+old behaviour of using the VPU allocation.

-Add the ability to interpret the high bits of the dreq specifier as
-flags to be included in the DMA_CS register. The motivation for this
-change is the ability to set the DISDEBUG flag for SD card transfers
-to avoid corruption when using the VPU debugger.

-
-[ Upstream commit 3500f1c589e92e0b6b1f8d31b4084fbde08d49cb ]
-
-Clicks and pops of various volumes can be produced while the device is
-opened, closed, put into and taken out of standby, or reconfigured.
-Fix this, by implementing the digital_mute interface, so that the
-output is muted during such operations.

- buffer
-
-The FIQ driver used a kzalloc'ed buffer for dummy_send,
-passing a kernel virtual address to the hardware block.
-The buffer is only ever used for a dummy read, so it
-should be harmless, but there is the chance that it will
-cause exceptions.
-
-Use a dma allocation so that we have a genuine bus address,
-and read from that.
-Free the allocation when done for good measure.

- within the kernel
-
-The driver was using an unsigned int as the handle to the outside world,
-and doing a nasty cast to the struct dmabuf when handed it back.
-This breaks badly with a 64 bit kernel where the pointer doesn't fit
-in an unsigned int.
-
-Switch to using a void* within the kernel. Reality is that it is
-a struct dma_buf*, but advertising it as such to other drivers seems
-to encourage the use of it as such, and I'm not sure on the implications
-of that.

+The dma_complete handling code calculates a virtual address for a page

+Subject: [PATCH] overlays: Fix multiple-instantiation of sc16is7xx*
+
+The registration of the fixed clocks uses the node name as the clock
+name, causing a clash if two clock nodes have the same name, regardless
+of the path to the node. Fix the issue by overwriting the clock node
+names using the value of the "addr" parameter, providing a crude
+disambiguation. (A bit of string pasting to form "sc16is752_clk_<addr>"
+would have been nice, but that is outside the abilities of the overlay
+parameter mechanism.)
+
+Also give the sc16is750-i2c overlay the xtal parameter for symmetry.

+Subject: [PATCH] bcm2835-mmc: Fix duplicate free_irq() on remove
+
+The BCM2835 MMC host driver requests its interrupt as a device-managed
+resource, so the interrupt is automatically freed after the driver is
+unbound.
+
+However on driver unbind, bcm2835_mmc_remove() frees the interrupt
+explicitly to avoid invocation of the interrupt handler after driver
+structures have been torn down.
+
+The interrupt is thus freed twice, leading to a WARN splat in
+__free_irq(). Fix by not requesting the interrupt as a device-managed
+resource.

+
+commit 16688453661b6d5159be558a1f8c1f54463a420f upstream.
+
+Add a type attribute so userspace is able to know how the data is stored as
+this can help taking the correct decision when selecting which device to
+use. This will also help program display the proper warnings when burning
+fuses for example.

- from param_get
-
-mmal-vchiq is a reimplementation of the userland library for MMAL.
-When getting a parameter, the client provides the storage and
-the size of the storage. The VPU then returns the size of the
-parameter that it wished to return, and as much as possible of
-that parameter is returned to the client.
-
-The implementation previously only returned the size provided
-by the VPU should it exceed the buffer size. So for parameters
-such as the supported encodings list the client had no idea
-how much of the provided storage had been populated.

++Generic device tree bindings for Real Time Clock devices
++========================================================
++
++This document describes generic bindings which can be used to describe Real Time
++Clock devices in a device tree.
++
++Required properties
++-------------------
++
++- compatible : name of RTC device following generic names recommended practice.
++
++For other required properties e.g. to describe register sets,
++clocks, etc. check the binding documentation of the specific driver.
++
++Optional properties
++-------------------
++
++- start-year : if provided, the default hardware range supported by the RTC is
++ shifted so the first usable year is the specified one.
++
++The following properties may not be supported by all drivers. However, if a
++driver wants to support one of the below features, it should adapt the bindings
++below.
++- trickle-resistor-ohms : Selected resistor for trickle charger. Should be given
++ if trickle charger should be enabled
++- trickle-diode-disable : Do not use internal trickle charger diode Should be
++ given if internal trickle charger diode should be
++ disabled
++- wakeup-source : Enables wake up of host system on alarm
++- quartz-load-femtofarads : The capacitive load of the quartz(x-tal),
++ expressed in femto Farad (fF).
++ The default value shall be listed (if optional),
++ and likewise all valid values.
++
++Trivial RTCs
++------------
++
++This is a list of trivial RTC devices that have simple device tree
++bindings, consisting only of a compatible field, an address and
++possibly an interrupt line.

-Subject: [PATCH 354/806] staging: mmal-vchiq: If the VPU returns an error,
- don't negate it
-
-There is an enum for the errors that the VPU can return.
-port_parameter_get was negating that value, but also using -EINVAL
-from the Linux error codes.
-Pass the VPU error code as positive values. Should the function
-need to pass a Linux failure, then return that as negative.

-Subject: [PATCH 355/806] staging: bcm2835_codec: Query supported formats from
- the component
-
-The driver was previously working with hard coded tables of
-which video formats were supported by each component.
-The components advertise this information via a MMAL parameter,
-so retrieve the information from there during probe, and store
-in the state structure for that device.

+Subject: [PATCH] ASoC: tlv320aic32x4: SND_SOC_DAPM_MICBIAS is
+ deprecated
+
+commit 04d979d7a7bac2f645cd827ea37e5ffa5b4e1f97 upstream.
+
+SND_SOC_DAPM_MICBIAS is deprecated, replace it with SND_SOC_DAPM_SUPPLY.
+
+MICBIAS voltage wasn't supplied to the microphone with the older
+SND_SOC_DAPM_MICBIAS widget, hence the microphone wouldn't work.
+
+This patch fixes the problem.

-Subject: [PATCH 356/806] staging: bcm2835_codec: Add support for the ISP as an
- M2M device
-
-The MMAL ISP component can also use this same V4L2 wrapper to
-provide a M2M format conversion and resizer.
-Instantiate 3 V4L2 devices now, one for each of decode, encode,
-and isp.
-The ISP currently doesn't expose any controls via V4L2, but this
-can be extended in the future.

+
+commit bf31cbfbe25001036e1e096b1c260bf871766ea5 upstream.
+
+Break the clock setting logic out from the main hw_params. It's
+rather large and unweildy and makes for a large function. This
+also better enables some of the following changes to the clock
+tree access in the driver.

-Subject: [PATCH 358/806] staging: bcm2835_codec: Fix handling of
- VB2_MEMORY_DMABUF buffers
-
-If the queue is configured as VB2_MEMORY_DMABUF then vb2_core_expbuf
-fails as it ensures the queue is defined as VB2_MEMORY_MMAP.
-
-Correct the handling so that we unmap the buffer from vcsm and the
-VPU on cleanup, and then correctly get the dma buf of the new buffer.

+
+commit 514b044cba667e4b7c383ec79b42b997e624b91d upstream.
+
+Model and manage the on-board PLL as a component in the Core
+Clock Framework. This should allow us to do some more complex
+clock management and power control. Also, some of the
+on-board chip clocks can be exposed to the outside, and this
+change will make those clocks easier to consume by other
+parts of the kernel.

+
+Model and manage codec clock input as a component in the Core
+Clock Framework. This should allow us to do some more complex
+clock management and power control. Also, some of the
+on-board chip clocks can be exposed to the outside, and this
+change will make those clocks easier to consume by other
+parts of the kernel.

- updates.
-
-We don't use the same async update path between fkms and normal kms,
-and the normal kms workaround ended up making us wait. This became a
-larger problem in rpi-4.14.y, as the USB HID update rate throttling
-got (accidentally?) dropped.

+Subject: [PATCH] ASoC: tlv320aic32x4: Model BDIV divider in CCF
+
+commit 9b484124ebd906c4d6bc826cc0d417e80cc1105c upstream.
+
+Model and manage BDIV divider as components in the Core
+Clock Framework. This should allow us to do some more complex
+clock management and power control. Also, some of the
+on-board chip clocks can be exposed to the outside, and this
+change will make those clocks easier to consume by other
+parts of the kernel.

-When handler of data_available interrupt is fired, queue_work ends up

-interrupt context. The fix was to run the handler from a thread context

+
+commit d25970b5fd51e9fcf0afbe190908ea4049454da4 upstream.
+
+Control the clock gating to the various clock components to use
+the CCF. This allows us to prepare_enalbe only 3 clocks and the
+relationships assigned to them will cause upstream clockss to
+enable automatically. Additionally we can do this in a single
+call to the CCF.

+Subject: [PATCH] ASoC: tlv320aic32x4: Dynamically Determine Clocking
+
+commit 96c3bb00239de4fb5f4ddca42c1f90d6d9b3c697 upstream.
+
+The existing code uses a static lookup table to determine the
+settings of the various clock devices on board the chip. This is
+limiting in a couple of ways. First, this doesn't allow for any
+master clock rates other than the three that have been
+precalculated. Additionally, new sample rates are difficult to
+add to the table. Witness that the chip is capable of 192000 Hz
+sampling, but it is not provided by this driver. Last, if the
+driver is clocked by something that isn't a crystal, the
+upstream clock may not be able to achieve exactly the rate
+requested in the driver. This will mean that clocking will be
+slightly off for the sampling clock or that it won't work at all.
+
+This patch determines the settings for all of the clocks at
+runtime considering the real conditions of the clocks in the
+system. The rules for the clocks are in TI's SLAA557 application
+guide on pages 37, 51 and 77.

- passing to VPU
-
-Currently the VPU allocates the contiguous buffer for the
-framebuffer.
-Try an alternate path first where we use dma_alloc_coherent
-and pass the buffer to the VPU. Should the VPU firmware not
-support that path, then free the buffer and revert to the
-old behaviour of using the VPU allocation.

-Subject: [PATCH 370/806] vcsm: Reduce scope of local functions
-
-The functions:
-
- vc_vchi_sm_send_msg
- vc_sm_ioctl_alloc
- vc_sm_ioctl_alloc_share
- vc_sm_ioctl_import_dmabuf
-
-Are declared without a prototype. They are not used outside of this
-module, thus - convert them to static functions.

- queue_setup failure
-
-queue_setup tries creating the relevant MMAL component and configures
-the input and output ports as we're expecting to start streaming.
-If the port configuration failed then it destroyed the component,
-but failed to clear the component handle, therefore release tried
-destroying the component again.
-Adds some logging should the port config fail as well.

+
+commit d3e6e374566e1154820a9a3dc82f7eef646fcf95 upstream.
+
+PowerTune controls the power level of the chip. On playback this
+indirectly controls things like the gain of the various output
+amplifiers. This can allow for the decrease of output levels
+from the codec. This adds controls for those power levels to
+the driver.

+Subject: [PATCH] dwc_otg: only do_split when we actually need to do a
+ split
+
+The previous test would fail if the root port was in fullspeed mode
+and there was a hub between the FS device and the root port. While
+the transfer worked, the schedule mangling performed for high-speed
+split transfers would break leading to an 8ms polling interval.

+Subject: [PATCH] Input: ili210x - fetch touchscreen geometry from DT
+
+commit f67cc3e927d8414ad3872e046764534ea1f5db0d upstream
+
+Fetching the geometry from the ILI251x registers seems unreliable and
+sometimes returns all zeroes. Add support for fetching the geometry and
+axis inversion from DT instead.

-
-The dma_complete handling code calculates a virtual address for a page
-then adds an offset, but if the offset is more than a page and HIGHMEM
-is in use then the summed address could be in an unmapped (or just
-incorrect) page.
-
-The upstream SDHOST driver allows for this possibility - copy the code
-that does so.

-Subject: [PATCH 380/806] overlays: Fix multiple-instantiation of sc16is7xx*
-
-The registration of the fixed clocks uses the node name as the clock
-name, causing a clash if two clock nodes have the same name, regardless
-of the path to the node. Fix the issue by overwriting the clock node
-names using the value of the "addr" parameter, providing a crude
-disambiguation. (A bit of string pasting to form "sc16is752_clk_<addr>"
-would have been nice, but that is outside the abilities of the overlay
-parameter mechanism.)
-
-Also give the sc16is750-i2c overlay the xtal parameter for symmetry.
-
-See: https://www.raspberrypi.org/forums/viewtopic.php?f=107&t=235650

-
-The BCM2835 MMC host driver requests a DMA channel on probe but neglects
-to release the channel in the probe error path and on driver unbind.
-
-I'm seeing this happen on every boot of the Compute Module 3: On first
-driver probe, DMA channel 2 is allocated and then leaked with a "could
-not get clk, deferring probe" message. On second driver probe, channel 4
-is allocated.
-
-Fix it.

-Subject: [PATCH 384/806] bcm2835-mmc: Fix duplicate free_irq() on remove
-
-The BCM2835 MMC host driver requests its interrupt as a device-managed
-resource, so the interrupt is automatically freed after the driver is
-unbound.
-
-However on driver unbind, bcm2835_mmc_remove() frees the interrupt
-explicitly to avoid invocation of the interrupt handler after driver
-structures have been torn down.
-
-The interrupt is thus freed twice, leading to a WARN splat in
-__free_irq(). Fix by not requesting the interrupt as a device-managed
-resource.

+Subject: [PATCH] sound: Fixes for audioinjector-octo under 4.19
+
+1. Move the DT alias declaration to the I2C shim in the cases
+where the shim is enabled. This works around a problem caused by a
+4.19 commit [1] that generates DT/OF uevents for I2C drivers.
+
+2. Fix the diagnostics in an error path of the soundcard driver to
+correctly identify the reason for the failure to load.
+
+3. Move the declaration of the clock node in the overlay outside
+the I2C node to avoid warnings.
+
+4. Sort the overlay nodes so that dependencies are only to earlier
+fragments, in an attempt to get runtime dtoverlay application to
+work (it still doesn't...)

-The BCM2835 MMC host driver sets the device's driver data pointer to
-NULL on ->remove() even though the driver core subsequently does the

+Subject: [PATCH] staging: bcm2835-audio: Clean up mutex locks
+
+commit ce4bb1aa271a97047b80ac917a5d91b54925913b upstream.
+
+snd-bcm2835 driver takes the lock with mutex_lock_interruptible() in
+all places, which don't make sense. Replace them with the simple
+mutex_lock().
+
+Also taking a mutex lock right after creating it for each PCM object
+is nonsense, too. It cannot be racy at that point. We can get rid of
+it.
+
+Last but not least, initializing chip->audio_mutex at each place is
+error-prone. Initialize properly at creating the chip object in
+snd_bcm2835_create() instead.

-Subject: [PATCH 391/806] staging: bcm2835-codec: Refactor default resolution
- code
-
-The default resolution code was different for each role
-as compressed formats need to pass bytesperline as 0 and
-set up customised buffer sizes.
-This is common setup, therefore amend get_sizeimage and
-get_bytesperline to do the correct thing whether compressed
-or uncompressed.

-commit 16688453661b6d5159be558a1f8c1f54463a420f upstream.
-
-Add a type attribute so userspace is able to know how the data is stored as
-this can help taking the correct decision when selecting which device to
-use. This will also help program display the proper warnings when burning
-fuses for example.

+Subject: [PATCH] staging: bcm2835-audio: Remove redundant spdif stream
+ ctls
+
+commit ab91e26229eaca2832df51e13c1285aea3be33ab upstream.
+
+The "IEC958 Playback Stream" control does basically the very same
+thing as "IEC958 Playback Default" redundantly. The former should
+have been stream-specific and restored after closing the stream, but
+we don't do in that way.
+
+Since it's nothing but confusion, remove this fake.

-
-upstream commit e6e7376cfd7b3f9b63de3a22792f64d9bfb2ab53.
-
-Add a driver for the MicroCrystal RV-3028. It is a SMT Real-Time Clock
-Module that incorporates an integrated CMOS circuit together with an XTAL.
-It has an i2c interface.
-
-The driver handles date/time, alarms, trickle charging, timestamping,
-frequency offset correction, EEPROM and NVRAM.

-+Generic device tree bindings for Real Time Clock devices
-+========================================================
-+
-+This document describes generic bindings which can be used to describe Real Time
-+Clock devices in a device tree.
-+
-+Required properties
-+-------------------
-+
-+- compatible : name of RTC device following generic names recommended practice.
-+
-+For other required properties e.g. to describe register sets,
-+clocks, etc. check the binding documentation of the specific driver.
-+
-+Optional properties
-+-------------------
-+
-+- start-year : if provided, the default hardware range supported by the RTC is
-+ shifted so the first usable year is the specified one.
-+
-+The following properties may not be supported by all drivers. However, if a
-+driver wants to support one of the below features, it should adapt the bindings
-+below.
-+- trickle-resistor-ohms : Selected resistor for trickle charger. Should be given
-+ if trickle charger should be enabled
-+- trickle-diode-disable : Do not use internal trickle charger diode Should be
-+ given if internal trickle charger diode should be
-+ disabled
-+- wakeup-source : Enables wake up of host system on alarm
-+- quartz-load-femtofarads : The capacitive load of the quartz(x-tal),
-+ expressed in femto Farad (fF).
-+ The default value shall be listed (if optional),
-+ and likewise all valid values.
-+
-+Trivial RTCs
-+------------
-+
-+This is a list of trivial RTC devices that have simple device tree
-+bindings, consisting only of a compatible field, an address and
-+possibly an interrupt line.

+Subject: [PATCH] staging: bcm2835-audio: Remove redundant substream
+ mask checks
+
+commit 14b1f4cba853a11c7b381ad919622f38eb194bd7 upstream.
+
+The avail_substreams bit mask is checked for the possible racy
+accesses, but this cannot happen in practice; i.e. the assignment and
+the check are superfluous.
+
+Let's rip them off.

+Subject: [PATCH] staging: bcm2835-audio: Fix mute controls, volume
+ handling cleanup
+
+commit 495e5a0d83d3902c741771f267a702ae19da8ab6 upstream.
+
+In the current code, the mute control is dealt in a special manner,
+modifying the current volume and saving the old volume, etc. This is
+inconsistent (e.g. change the volume while muted, then unmute), and
+way too complex.
+
+Also, the whole volume handling code has conversion between ALSA
+volume and raw volume values, which can lead to another
+inconsistency and complexity.
+
+This patch simplifies these points:
+- The ALSA volume value is saved in chip->volume
+- volume->mute saves the mute state
+- The mute state is evaluated only when the actual volume is passed to
+ the hardware, bcm2835_audio_set_ctls()

-SND_SOC_DAPM_MICBIAS is deprecated, replace it with SND_SOC_DAPM_SUPPLY.
-
-MICBIAS voltage wasn't supplied to the microphone with the older

+bcm2835_audio_setup(), bcm2835_audio_flush_buffers() and

-
-commit bf31cbfbe25001036e1e096b1c260bf871766ea5 upstream.
-
-Break the clock setting logic out from the main hw_params. It's
-rather large and unweildy and makes for a large function. This
-also better enables some of the following changes to the clock

+
+commit ad13924de6b07cb52714ea1809c57b2e72a24504 upstream.
+
+All the alsa_stream->open flag checks in the current code are
+redundant, and they cannot be racy. For the code simplification,
+let's remove the flag and its check.

+ check
+
+commit 02f2376321d75e78117f39ff81f215254ee6b4ef upstream.
+
+The running flag of alsa_stream is basically useless. The running
+state is strictly controlled in ALSA PCM core side, hence the check in
+PCM trigger and close callbacks are superfluous.
+
+Also, the prefill ack at trigger start became superfluous nowadays
+with the ALSA PCM core update.
+
+Let's rip them off.

-
-Model and manage the on-board PLL as a component in the Core
-Clock Framework. This should allow us to do some more complex
-clock management and power control. Also, some of the
-on-board chip clocks can be exposed to the outside, and this
-change will make those clocks easier to consume by other

+Subject: [PATCH] staging: bcm2835-audio: Fix incorrect draining
+ handling
+
+commit 7d2a91f5f1bcf08ca257bcf1ed9721fcd341f834 upstream.
+
+The handling of SNDRV_PCM_TRIGGER_STOP at the trigger callback is
+incorrect: when the STOP is issued, the driver is supposed to drop the
+stream immediately. Meanwhile bcm2835 driver checks the DRAINING
+state and tries to issue some different command.
+
+This patch straightens things a bit, dropping the incorrect state
+checks. The draining behavior would be still not perfect at this
+point, but will be improved in a later patch.

-Subject: [PATCH 400/806] ASoC: tlv320aic32x4: Model CODEC_CLKIN in CCF
-
-commit fd2df3aeafa4b4cc468d58e147e0822967034b71 upstream.
-
-Model and manage codec clock input as a component in the Core
-Clock Framework. This should allow us to do some more complex
-clock management and power control. Also, some of the
-on-board chip clocks can be exposed to the outside, and this
-change will make those clocks easier to consume by other
-parts of the kernel.

-
-commit a51b50062091619915c5155085bbe13a7aca6903 upstream.
-
-Model and manage DAC/ADC dividers as components in the Core
-Clock Framework. This should allow us to do some more complex
-clock management and power control. Also, some of the
-on-board chip clocks can be exposed to the outside, and this
-change will make those clocks easier to consume by other
-parts of the kernel.

+ instead
+
+commit b8f7fdd50890b848e085c0519469aed4ff4d9b54 upstream.
+
+Some fields in alsa_stream are the values we keep already in PCM
+runtime object, hence they are redundant. Use the standard PCM
+runtime values instead of the private copies.

-Subject: [PATCH 402/806] ASoC: tlv320aic32x4: Model BDIV divider in CCF
-
-commit 9b484124ebd906c4d6bc826cc0d417e80cc1105c upstream.
-
-Model and manage BDIV divider as components in the Core
-Clock Framework. This should allow us to do some more complex
-clock management and power control. Also, some of the
-on-board chip clocks can be exposed to the outside, and this
-change will make those clocks easier to consume by other
-parts of the kernel.

-
-Control the clock gating to the various clock components to use
-the CCF. This allows us to prepare_enalbe only 3 clocks and the
-relationships assigned to them will cause upstream clockss to
-enable automatically. Additionally we can do this in a single
-call to the CCF.

-Subject: [PATCH 405/806] ASoC: tlv320aic32x4: Dynamically Determine Clocking
-
-commit 96c3bb00239de4fb5f4ddca42c1f90d6d9b3c697 upstream.
-
-The existing code uses a static lookup table to determine the
-settings of the various clock devices on board the chip. This is
-limiting in a couple of ways. First, this doesn't allow for any
-master clock rates other than the three that have been
-precalculated. Additionally, new sample rates are difficult to
-add to the table. Witness that the chip is capable of 192000 Hz
-sampling, but it is not provided by this driver. Last, if the
-driver is clocked by something that isn't a crystal, the
-upstream clock may not be able to achieve exactly the rate
-requested in the driver. This will mean that clocking will be
-slightly off for the sampling clock or that it won't work at all.
-
-This patch determines the settings for all of the clocks at
-runtime considering the real conditions of the clocks in the
-system. The rules for the clocks are in TI's SLAA557 application
-guide on pages 37, 51 and 77.

+Subject: [PATCH] staging: bcm2835-audio: Drop debug messages in
+ bcm2835-pcm.c
+
+commit 055e1c330d04df87d4730a5db837161c11ddaafc upstream.
+
+These debug messages worsen the code readability a lot while they give
+little debuggability (which we already have via tracing, in anyway).
+
+Let's clean them up. This allows us to reduce the
+snd_bcm2835_pcm_lib_ioctl() function to be a direct call of the
+snd_pcm_lib_ioctl callback (like most other drivers do), too.

+Subject: [PATCH] staging: bcm2835-audio: Code refactoring of vchiq
+ accessor codes
+
+commit 769a8e9bf5cf39813f52962fdafdf7e4d52ad585 upstream.
+
+This is a cleanup and code refactoring in bcm2835-vchiq.c.
+
+The major code changes are to provide local helpers for easier use of
+lock / unlock, and message passing with/without response wait. This
+allows us to reduce lots of open codes.
+
+Also, the max packet is set at opening the stream, not at each time
+when the write gets called.

+Subject: [PATCH] staging: bcm2835-audio: Operate non-atomic PCM ops
+
+commit 5c7883e5f27e829f3f3a2ba174d4a724bfd5f026 upstream.
+
+This is the most significant part in the patch series.
+
+The bcm2835-audio driver used to queue the commands to vc04 core via
+workqueue, but basically the whole accesses to vc04 core are done in
+the sleepable context, including the callback calls. In such a case,
+rewriting the code using non-atomic PCM ops will simplify the logic a
+lot.
+
+This patch does it: all workqueue are gone and each former-work
+implementation is now directly called from PCM ops like trigger and
+write transfer.
+
+Along with it, the DMA position updater, bcm2835_playback_fifo(), was
+also rewritten to use a simpler logic. Now it handles the XRUN and
+draining properly by calling snd_pcm_stop() conditionally.
+
+The current position is kept in atomic_t value so that it can be read
+concurrently from the pointer callback.
+
+Also, the bcm2835_audio_instance object is allocated at the beginning
+of bcm2835_audio_open(). This makes the resource management clearer.

+
+commit 898001a0c845cefe5d47d133485712412853f0a8 upstream.
+
+Instead of allocating a separate snd_device object, let snd_card_new()
+allocate the private resource. This simplifies the code.

+ helpers
+
+commit b7584b64168208ebc14160770c0966b8b12fc16b upstream.
+
+For making the whole code more consistent, replace the home-made debug
+print macros with the standard dev_err() & co.

-
-commit d3e6e374566e1154820a9a3dc82f7eef646fcf95 upstream.
-
-PowerTune controls the power level of the chip. On playback this
-indirectly controls things like the gain of the various output
-amplifiers. This can allow for the decrease of output levels
-from the codec. This adds controls for those power levels to
-the driver.

+Subject: [PATCH] staging: bcm2835-audio: Use coherent device buffers
+
+commit ad29c6e6cbf6f2af7362b043adad51a3be3d39c7 upstream.
+
+The memory access to the pages allocated with
+SNDRV_DMA_TYPE_CONTINUOUS are basically non-coherent, and it becomes a
+problem when a process accesses via mmap.
+
+For the more consistent access, use the device coherent memory, just
+by replacing the call pattern in the allocator helpers.
+
+The only point we need to be careful for is the device object passed
+there; since bcm2835-audio driver creates fake devices and each card
+is created on top of that, we need to pass its parent device as the
+real device object.

-
-The previous test would fail if the root port was in fullspeed mode
-and there was a hub between the FS device and the root port. While
-the transfer worked, the schedule mangling performed for high-speed
-split transfers would break leading to an 8ms polling interval.

+
+The recent ALSA PCM core supports the SNDRV_PCM_INFO_SYNC_APPLPTR flag
+indicating that the driver needs the ack call at each appl_ptr
+update. This is requirement for the indirect PCM implementations like

+Subject: [PATCH] staging: bcm2835-audio: Simplify PCM creation helpers
+
+commit 74470ffeb9aed5548654cfca881bf1d7469fe9c4 upstream.
+
+All three functions to create PCM objects are fairly resemble, and can
+be unified to a single common helper.

+ management
+
+commit 872ae2d63d516a2a3b9c833d8685afcfa7814542 upstream.
+
+Instead of creating a dummy child device to manage the card object,
+just use devm stuff directly for releasing with snd_card_free().
+This results in a lot of code reduction.
+
+Since the dummy child devices are gone, the device object to be passed
+to the memory allocator needs to be adjusted as well.

+The device communicates with the audio core using FOURCC codes. The

-Subject: [PATCH 421/806] dwc_otg: fix locking around dequeueing and killing
- URBs
-
-kill_urbs_in_qh_list() is practically only ever called with the fiq lock
-already held, so don't spinlock twice in the case where we need to cancel
-an isochronous transfer.
-
-Also fix up a case where the global interrupt register could be read with
-the fiq lock not held.
-
-Fixes the deadlock seen in https://github.com/raspberrypi/linux/issues/2907

+
+The memory is being allocated with devres_alloc(), wich ultimately uses

-Subject: [PATCH 426/806] sound: Fixes for audioinjector-octo under 4.19
-
-1. Move the DT alias declaration to the I2C shim in the cases
-where the shim is enabled. This works around a problem caused by a
-4.19 commit [1] that generates DT/OF uevents for I2C drivers.
-
-2. Fix the diagnostics in an error path of the soundcard driver to
-correctly identify the reason for the failure to load.
-
-3. Move the declaration of the clock node in the overlay outside
-the I2C node to avoid warnings.
-
-4. Sort the overlay nodes so that dependencies are only to earlier
-fragments, in an attempt to get runtime dtoverlay application to
-work (it still doesn't...)

+
+The following tasks were completed or not the right solution:

+
+2/3- Fixed by Takashi Iwai here: https://lkml.org/lkml/2018/9/4/587

+Also, adds a new task as per mailing list conversation.

+
+commit a105a3a72824e0ac685a0711a67e4dbe29de62d0 upstream.
+
+When the BCM2835 audio output is used, userspace sees a jitter up to 10ms
+in the audio position, aka "delay" -- the number of frames that must
+be output before a new frame would be played.
+Make this a bit nicer for userspace by interpolating the position
+using the CPU clock.
+The overhead is small -- an extra ktime_get() every time a GPU message
+is sent -- and another call and a few calculations whenever the delay
+is sought from userland.
+At 48,000 frames per second, i.e. approximately 20 microseconds per
+frame, it would take a clock inaccuracy of
+20 microseconds in 10 milliseconds -- 2,000 parts per million --
+to result in an inaccurate estimate, whereas
+crystal- or resonator-based clocks typically have an
+inaccuracy of 10s to 100s of parts per million.

+
+commit 1e55d56344b0777d6cee9b9e4a813d53728ee798 upstream.
+
+There is not much value behind this boilerplate, so use

+
+commit 438fc48260a0afc4cee733e5bc20234ff2bbef56 upstream.
+
+Just like the bcm2835-video make this a platform driver which is probed
+by vchiq. In order to change the number of channels use a module
+parameter instead, but use the maximum as default.

+dwc_otg allocates DMA-coherent buffers in atomic context for misaligned

+Subject: [PATCH] smsc95xx: dynamically fix up TX buffer alignment with
+ padding bytes
+
+dwc_otg requires a 32-bit aligned buffer start address, otherwise
+expensive bounce buffers are used. The LAN951x hardware can skip up to
+3 bytes between the TX header and the start of frame data, which can
+be used to force alignment of the URB passed to dwc_otg.

-Subject: [PATCH 434/806] staging: bcm2835-audio: Clean up mutex locks
-
-commit ce4bb1aa271a97047b80ac917a5d91b54925913b upstream.
-
-snd-bcm2835 driver takes the lock with mutex_lock_interruptible() in
-all places, which don't make sense. Replace them with the simple
-mutex_lock().
-
-Also taking a mutex lock right after creating it for each PCM object
-is nonsense, too. It cannot be racy at that point. We can get rid of
-it.
-
-Last but not least, initializing chip->audio_mutex at each place is
-error-prone. Initialize properly at creating the chip object in
-snd_bcm2835_create() instead.

-
-The "IEC958 Playback Stream" control does basically the very same
-thing as "IEC958 Playback Default" redundantly. The former should
-have been stream-specific and restored after closing the stream, but
-we don't do in that way.

+ truncation
+
+The calculation converting from V4L2 bytesperline to MMAL
+width had an operator ordering issue that lead to Bayer raw 10
+(and 12 and 14) setting an incorrect stride for the buffer.
+Correct this operation ordering issue.

-The avail_substreams bit mask is checked for the possible racy

-Subject: [PATCH 438/806] staging: bcm2835-audio: Fix mute controls, volume
- handling cleanup
-
-commit 495e5a0d83d3902c741771f267a702ae19da8ab6 upstream.
-
-In the current code, the mute control is dealt in a special manner,
-modifying the current volume and saving the old volume, etc. This is
-inconsistent (e.g. change the volume while muted, then unmute), and
-way too complex.
-
-Also, the whole volume handling code has conversion between ALSA
-volume and raw volume values, which can lead to another
-inconsistency and complexity.
-
-This patch simplifies these points:
-- The ALSA volume value is saved in chip->volume
-- volume->mute saves the mute state
-- The mute state is evaluated only when the actual volume is passed to
- the hardware, bcm2835_audio_set_ctls()

- calls
-
-commit 124950ebe9fa8547c59e8d4acc8d6c59e6278ed6 upstream.
-
-bcm2835_audio_setup(), bcm2835_audio_flush_buffers() and
-bcm2835_audio_flush_playback_buffers() functions do implement
-nothing.
-
-Also, bcm2835_audio_set_ctls() is already called inside
-bcm2835_audio_set_params(), so the later call is superfluous.
-
-This patch removes these superfluous implementations.

-
-commit 02f2376321d75e78117f39ff81f215254ee6b4ef upstream.
-
-The running flag of alsa_stream is basically useless. The running
-state is strictly controlled in ALSA PCM core side, hence the check in
-PCM trigger and close callbacks are superfluous.
-
-Also, the prefill ack at trigger start became superfluous nowadays
-with the ALSA PCM core update.
-
-Let's rip them off.

- handling
-
-commit 7d2a91f5f1bcf08ca257bcf1ed9721fcd341f834 upstream.
-
-The handling of SNDRV_PCM_TRIGGER_STOP at the trigger callback is
-incorrect: when the STOP is issued, the driver is supposed to drop the
-stream immediately. Meanwhile bcm2835 driver checks the DRAINING
-state and tries to issue some different command.
-
-This patch straightens things a bit, dropping the incorrect state
-checks. The draining behavior would be still not perfect at this
-point, but will be improved in a later patch.

+Subject: [PATCH] Revert "video: bcm2708_fb: Try allocating on the ARM
+ and passing to VPU"
+
+This reverts commit ca36c709fce57e8023d2b8b354376bf161601a49.
+
+The driver tries a cma_alloc to avoid using gpu_mem, but should
+that fail the core code is logging an error with no easy way to
+test whether it will succeed or fail first.
+
+Revert until we either totally give up on gpu_mem and increase
+CMA always, or find a way to try an allocation.

- instead
-
-commit b8f7fdd50890b848e085c0519469aed4ff4d9b54 upstream.
-
-Some fields in alsa_stream are the values we keep already in PCM
-runtime object, hence they are redundant. Use the standard PCM
-runtime values instead of the private copies.

+Subject: [PATCH] w1: ds2408: reset on output_write retry with readback
+
+commit 49695ac46861180baf2b2b92c62da8619b6bf28f upstream.
+
+When we have success in 'Channel Access Write' but reading back latch
+states fails, a write is retried without doing a proper slave reset.
+This leads to protocol errors as the slave treats the next 'Channel
+Access Write' as the continuation of previous command.
+
+This commit is fixing this by making sure if the retry loop re-runs, a
+reset is performed, whatever the failure (CONFIRM_BYTE or the read
+back).
+
+The loop was quite due for a cleanup and this change mandated it. By
+isolating the CONFIG_W1_SLAVE_DS2408_READBACK case into it's own
+function, we vastly reduce the visual and branching(runtime and
+compile-time) noise.

- bcm2835-pcm.c
-
-commit 055e1c330d04df87d4730a5db837161c11ddaafc upstream.
-
-These debug messages worsen the code readability a lot while they give
-little debuggability (which we already have via tracing, in anyway).
-
-Let's clean them up. This allows us to reduce the
-snd_bcm2835_pcm_lib_ioctl() function to be a direct call of the
-snd_pcm_lib_ioctl callback (like most other drivers do), too.

-commit f0eb15d055380ff127e5f12c8fad2b36bdb3c006 upstream.
-
-The chip->audio_mutex is used basically for protecting the opened
-stream assignment, and the prepare callback is irrelevant with it.

+Subject: [PATCH] Bluetooth: Check key sizes only when Secure Simple
+ Pairing is enabled
+
+The encryption is only mandatory to be enforced when both sides are using
+Secure Simple Pairing and this means the key size check makes only sense
+in that case.
+
+On legacy Bluetooth 2.0 and earlier devices like mice the encryption was
+optional and thus causing an issue if the key size check is not bound to
+using Secure Simple Pairing.

-
-commit 326a6edcb2ada56375bd7d3fc24c83f58e8da7f3 upstream.
-
-The bcm2835_audio_instance object contains the array of
-VCHI_SERVICE_HANDLE_T, while the code assumes and uses only the first
-element explicitly. Let's reduce to a single vchi handle for
-simplifying the code.

-Subject: [PATCH 452/806] staging: bcm2835-audio: Code refactoring of vchiq
- accessor codes
-
-commit 769a8e9bf5cf39813f52962fdafdf7e4d52ad585 upstream.
-
-This is a cleanup and code refactoring in bcm2835-vchiq.c.
-
-The major code changes are to provide local helpers for easier use of
-lock / unlock, and message passing with/without response wait. This
-allows us to reduce lots of open codes.
-
-Also, the max packet is set at opening the stream, not at each time
-when the write gets called.

-Subject: [PATCH 453/806] staging: bcm2835-audio: Operate non-atomic PCM ops
-
-commit 5c7883e5f27e829f3f3a2ba174d4a724bfd5f026 upstream.
-
-This is the most significant part in the patch series.
-
-The bcm2835-audio driver used to queue the commands to vc04 core via
-workqueue, but basically the whole accesses to vc04 core are done in
-the sleepable context, including the callback calls. In such a case,
-rewriting the code using non-atomic PCM ops will simplify the logic a
-lot.
-
-This patch does it: all workqueue are gone and each former-work
-implementation is now directly called from PCM ops like trigger and
-write transfer.
-
-Along with it, the DMA position updater, bcm2835_playback_fifo(), was
-also rewritten to use a simpler logic. Now it handles the XRUN and
-draining properly by calling snd_pcm_stop() conditionally.
-
-The current position is kept in atomic_t value so that it can be read
-concurrently from the pointer callback.
-
-Also, the bcm2835_audio_instance object is allocated at the beginning
-of bcm2835_audio_open(). This makes the resource management clearer.

-Instead of allocating a separate snd_device object, let snd_card_new()

+Subject: [PATCH] overlays: Standardise on compatible="brcm,bcm2835"
+
+Curb the proliferation of compatible string combinations by
+standardising on "brcm,bcm2835" to denote BCM2835 and its descendants.
+
+As nothing in the firmware or kernel is checking overlay compatible
+strings, this should be a purely cosmetic change.

-Date: Tue, 4 Sep 2018 17:58:51 +0200
-Subject: [PATCH 455/806] staging: bcm2835-audio: Use standard error print
- helpers
-
-commit b7584b64168208ebc14160770c0966b8b12fc16b upstream.
-
-For making the whole code more consistent, replace the home-made debug
-print macros with the standard dev_err() & co.

+Subject: [PATCH] BCM270X_DT: Add non-removable clone of mmc node
+
+non-removable is a boolean property, and as such can't be unset by an
+overlay if it is set in a base DTB. Until now the workaround for this
+problem has been for overlays to clone non-removable nodes without
+the offending property, but this involves a lot of unnecessary
+replication. Instead, add a clone of the mmc node with non-removable
+already set to the base DTB, selecting the required version using
+the status properties.

-
-commit ad29c6e6cbf6f2af7362b043adad51a3be3d39c7 upstream.
-
-The memory access to the pages allocated with
-SNDRV_DMA_TYPE_CONTINUOUS are basically non-coherent, and it becomes a
-problem when a process accesses via mmap.
-
-For the more consistent access, use the device coherent memory, just
-by replacing the call pattern in the allocator helpers.
-
-The only point we need to be careful for is the device object passed
-there; since bcm2835-audio driver creates fake devices and each card
-is created on top of that, we need to pass its parent device as the
-real device object.

-
-The recent ALSA PCM core supports the SNDRV_PCM_INFO_SYNC_APPLPTR flag
-indicating that the driver needs the ack call at each appl_ptr
-update. This is requirement for the indirect PCM implementations like
-bcm2835-audio driver, too.

+Subject: [PATCH] BCM270X_DT: Rename Pi Zero W DT files
+
+The downtream Pi Zero W dts file uses the digit 0, whereas upstream
+chose to spell it out - "zero-w". The firmware has, for a long time,
+looked for bcm2708-rpi-zero-w.dtb first before falling back to the
+numerical version. Therefore it is better to follow upstream and
+make the switch to "bcm2708-rpi-zero-w".
+
+At the same time, remove some overrides that duplicate values
+inherited from the shared .dtsi files.

- management
-
-commit 872ae2d63d516a2a3b9c833d8685afcfa7814542 upstream.
-
-Instead of creating a dummy child device to manage the card object,
-just use devm stuff directly for releasing with snd_card_free().
-This results in a lot of code reduction.
-
-Since the dummy child devices are gone, the device object to be passed
-to the memory allocator needs to be adjusted as well.

-The device communicates with the audio core using FOURCC codes. The

+Subject: [PATCH] i2c: bcm2835: Model Divider in CCF
+
+Commit bebff81fb8b9216eb4fba22cf910553621ae3477 upstream.
+
+Model the I2C bus clock divider as a part of the Core Clock Framework.
+Primarily this removes the clk_get_rate() call from each transfer.
+This call causes problems for slave drivers that themselves have
+internal clock components that are controlled by an I2C interface.
+When the slave's internal clock component is prepared, the prepare
+lock is obtained, and it makes calls to the I2C subsystem to
+command the hardware to activate the clock. In order to perform
+the I2C transfer, this driver sets the divider, which requires
+it to get the parent clock rate, which it does with clk_get_rate().
+Unfortunately, this function will try to take the clock prepare
+lock, which is already held by the slave's internal clock calls
+creating a deadlock.
+
+Modeling the divider in the CCF natively removes this dependency
+and the divider value is only set upon changing the bus clock
+frequency or changes in the parent clock that cascade down to this
+divisor. This obviates the need to set the divider with every
+transfer and avoids the deadlock described above. It also should
+provide better clock debugging and save a few cycles on each
+transfer due to not having to recalcuate the divider value.

-Subject: [PATCH 470/806] staging: bcm2835-audio: interpolate audio delay
-
-commit a105a3a72824e0ac685a0711a67e4dbe29de62d0 upstream.
-
-When the BCM2835 audio output is used, userspace sees a jitter up to 10ms
-in the audio position, aka "delay" -- the number of frames that must
-be output before a new frame would be played.
-Make this a bit nicer for userspace by interpolating the position
-using the CPU clock.
-The overhead is small -- an extra ktime_get() every time a GPU message
-is sent -- and another call and a few calculations whenever the delay
-is sought from userland.
-At 48,000 frames per second, i.e. approximately 20 microseconds per
-frame, it would take a clock inaccuracy of
-20 microseconds in 10 milliseconds -- 2,000 parts per million --
-to result in an inaccurate estimate, whereas
-crystal- or resonator-based clocks typically have an
-inaccuracy of 10s to 100s of parts per million.

-
-Just like the bcm2835-video make this a platform driver which is probed
-by vchiq. In order to change the number of channels use a module
-parameter instead, but use the maximum as default.

+ whole PM block. (v4)
+
+It was covering part of the PM block's range, up to the WDT regs. To
+support the rest of the PM block's functionality, we need the full
+register range plus the AXI Async Bridge regs for PM sequencing.
+
+This doesn't convert any of the consumers over to the new binding yet,
+since we will need to be careful in coordinating our usage of firmware
+services that might power domains on and off versus the bcm2835-pm
+driver's access of those same domains.

- padding bytes
-
-dwc_otg requires a 32-bit aligned buffer start address, otherwise
-expensive bounce buffers are used. The LAN951x hardware can skip up to
-3 bytes between the TX header and the start of frame data, which can
-be used to force alignment of the URB passed to dwc_otg.

+
+The change which introduced CONFIG_BCM2835_FAST_MEMCPY unconditionally
+changed the behaviour of arm_copy_from_user. The page pinning code
+is not safe on ARMv7 if LPAE & high memory is enabled and causes
+crashes which look like PTE corruption.
+
+Make __copy_from_user_memcpy conditional on CONFIG_2835_FAST_MEMCPY=y
+which is really an ARMv6 / Pi1 optimization and not necessary on newer
+ARM processors.

+Subject: [PATCH] PCI: brcmstb: Add Broadcom STB PCIe host controller
+ driver
+
+This commit adds the basic Broadcom STB PCIe controller. Missing is
+the ability to process MSI and also handle dma-ranges for inbound
+memory accesses. These two functionalities are added in subsequent
+commits.
+
+The PCIe block contains an MDIO interface. This is a local interface
+only accessible by the PCIe controller. It cannot be used or shared
+by any other HW. As such, the small amount of code for this
+controller is included in this driver as there is little upside to put
+it elsewhere.

+Subject: [PATCH] PCI: brcmstb: Add dma-range mapping for inbound
+ traffic
+
+The Broadcom STB PCIe host controller is intimately related to the
+memory subsystem. This close relationship adds complexity to how cpu
+system memory is mapped to PCIe memory. Ideally, this mapping is an
+identity mapping, or an identity mapping off by a constant. Not so in
+this case.
+
+Consider the Broadcom reference board BCM97445LCC_4X8 which has 6 GB
+of system memory. Here is how the PCIe controller maps the
+system memory to PCIe memory:
+
+ memc0-a@[ 0....3fffffff] <=> pci@[ 0....3fffffff]
+ memc0-b@[100000000...13fffffff] <=> pci@[ 40000000....7fffffff]
+ memc1-a@[ 40000000....7fffffff] <=> pci@[ 80000000....bfffffff]
+ memc1-b@[300000000...33fffffff] <=> pci@[ c0000000....ffffffff]
+ memc2-a@[ 80000000....bfffffff] <=> pci@[100000000...13fffffff]
+ memc2-b@[c00000000...c3fffffff] <=> pci@[140000000...17fffffff]
+
+Although there are some "gaps" that can be added between the
+individual mappings by software, the permutation of memory regions for
+the most part is fixed by HW. The solution of having something close
+to an identity mapping is not possible.
+
+The idea behind this HW design is that the same PCIe module can
+act as an RC or EP, and if it acts as an EP it concatenates all
+of system memory into a BAR so anything can be accessed. Unfortunately,
+when the PCIe block is in the role of an RC it also presents this
+"BAR" to downstream PCIe devices, rather than offering an identity map
+between its system memory and PCIe space.
+
+Suppose that an endpoint driver allocs some DMA memory. Suppose this
+memory is located at 0x6000_0000, which is in the middle of memc1-a.
+The driver wants a dma_addr_t value that it can pass on to the EP to
+use. Without doing any custom mapping, the EP will use this value for
+DMA: the driver will get a dma_addr_t equal to 0x6000_0000. But this
+won't work; the device needs a dma_addr_t that reflects the PCIe space
+address, namely 0xa000_0000.
+
+So, essentially the solution to this problem must modify the
+dma_addr_t returned by the DMA routines routines. There are two
+ways (I know of) of doing this:
+
+(a) overriding/redefining the dma_to_phys() and phys_to_dma() calls
+that are used by the dma_ops routines. This is the approach of
+
+ arch/mips/cavium-octeon/dma-octeon.c
+
+In ARM and ARM64 these two routines are defiend in asm/dma-mapping.h
+as static inline functions.
+
+(b) Subscribe to a notifier that notifies when a device is added to a
+bus. When this happens, set_dma_ops() can be called for the device.
+This method is mentioned in:
+
+ http://lxr.free-electrons.com/source/drivers/of/platform.c?v=3.16#L152
+
+where it says as a comment
+
+ "In case if platform code need to use own special DMA
+ configuration, it can use Platform bus notifier and
+ handle BUS_NOTIFY_ADD_DEVICE event to fix up DMA
+ configuration."
+
+Solution (b) is what this commit does. It uses its own set of
+dma_ops which are wrappers around the arch_dma_ops. The
+wrappers translate the dma addresses before/after invoking
+the arch_dma_ops, as appropriate.

-
-The ISP has no need for heights to be a multiple of macroblock
-sizes, therefore doesn't require the align on the height.
-Remove it for the ISP role. (It is required for the codecs).

+Subject: [PATCH] PCI: brcmstb: Add MSI capability
+
+This commit adds MSI to the Broadcom STB PCIe host controller. It does
+not add MSIX since that functionality is not in the HW. The MSI
+controller is physically located within the PCIe block, however, there
+is no reason why the MSI controller could not be moved elsewhere in
+the future.
+
+Since the internal Brcmstb MSI controller is intertwined with the PCIe
+controller, it is not its own platform device but rather part of the
+PCIe platform device.

++Brcmstb PCIe Host Controller Device Tree Bindings
++
++Required Properties:
++- compatible
++ "brcm,bcm7425-pcie" -- for 7425 family MIPS-based SOCs.
++ "brcm,bcm7435-pcie" -- for 7435 family MIPS-based SOCs.
++ "brcm,bcm7445-pcie" -- for 7445 and later ARM based SOCs (not including
++ the 7278).
++ "brcm,bcm7278-pcie" -- for 7278 family ARM-based SOCs.
++
++- reg -- the register start address and length for the PCIe reg block.
++- interrupts -- two interrupts are specified; the first interrupt is for
++ the PCI host controller and the second is for MSI if the built-in
++ MSI controller is to be used.
++- interrupt-names -- names of the interrupts (above): "pcie" and "msi".
++- #address-cells -- set to <3>.
++- #size-cells -- set to <2>.
++- #interrupt-cells: set to <1>.
++- interrupt-map-mask and interrupt-map, standard PCI properties to define the
++ mapping of the PCIe interface to interrupt numbers.
++- ranges: ranges for the PCI memory and I/O regions.
++- linux,pci-domain -- should be unique per host controller.
++
++Optional Properties:
++- clocks -- phandle of pcie clock.
++- clock-names -- set to "sw_pcie" if clocks is used.
++- dma-ranges -- Specifies the inbound memory mapping regions when
++ an "identity map" is not possible.
++- msi-controller -- this property is typically specified to have the
++ PCIe controller use its internal MSI controller.
++- msi-parent -- set to use an external MSI interrupt controller.
++- brcm,enable-ssc -- (boolean) indicates usage of spread-spectrum clocking.
++- max-link-speed -- (integer) indicates desired generation of link:
++ 1 => 2.5 Gbps (gen1), 2 => 5.0 Gbps (gen2), 3 => 8.0 Gbps (gen3).

-The driver tries a cma_alloc to avoid using gpu_mem, but should

-Revert until we either totally give up on gpu_mem and increase

-Subject: [PATCH 492/806] w1: ds2408: reset on output_write retry with readback
-
-commit 49695ac46861180baf2b2b92c62da8619b6bf28f upstream.
-
-When we have success in 'Channel Access Write' but reading back latch
-states fails, a write is retried without doing a proper slave reset.
-This leads to protocol errors as the slave treats the next 'Channel
-Access Write' as the continuation of previous command.
-
-This commit is fixing this by making sure if the retry loop re-runs, a
-reset is performed, whatever the failure (CONFIRM_BYTE or the read
-back).
-
-The loop was quite due for a cleanup and this change mandated it. By
-isolating the CONFIG_W1_SLAVE_DS2408_READBACK case into it's own
-function, we vastly reduce the visual and branching(runtime and
-compile-time) noise.

+Subject: [PATCH] bcmgenet: Better coalescing parameter defaults
+
+Set defaults for TX and RX packet coalescing to be equivalent to:
+
+ # ethtool -C eth0 tx-frames 10
+ # ethtool -C eth0 rx-usecs 50
+
+This may be something we want to set via DT parameters in the
+future.

+Subject: [PATCH] net: genet: enable link energy detect powerdown for
+ external PHYs
+
+There are several warts surrounding bcmgenet_mii_probe() as this
+function is called from ndo_open, but it's calling registration-type
+functions. The probe should be called at probe time and refactored
+such that the PHY device data can be extracted to limit the scope
+of this flag to Broadcom PHYs.
+
+For now, pass this flag in as it puts our attached PHY into a low-power
+state when disconnected.

-Subject: [PATCH 497/806] Bluetooth: Check key sizes only when Secure Simple
- Pairing is enabled
-
-The encryption is only mandatory to be enforced when both sides are using
-Secure Simple Pairing and this means the key size check makes only sense
-in that case.
-
-On legacy Bluetooth 2.0 and earlier devices like mice the encryption was
-optional and thus causing an issue if the key size check is not bound to
-using Secure Simple Pairing.

+Subject: [PATCH] usb: xhci: Disable the XHCI 5 second timeout
+
+If the VL805 EEPROM has not been programmed then boot will hang for five
+seconds. The timeout seems to be arbitrary and is an unecessary
+delay on the first boot. Remove the timeout.
+
+This is common code and probably can't be upstreamed unless the timeout
+can be configurable somehow or perhaps the XHCI driver can be skipped
+on the first boot.

-
-Curb the proliferation of compatible string combinations by

-
-As nothing in the firmware or kernel is checking overlay compatible
-strings, this should be a purely cosmetic change.

+Subject: [PATCH] usb: xhci: hack xhci_urb_enqueue to support
+ hid.mousepoll behaviour
+
+xHCI creates endpoint contexts directly from the device's endpoint
+data, so submitting URBs with urb->interval different from the hardware
+interval has no effect.
+
+Add an explicit reconfiguration of the endpoint context when requested,
+which will happen only when the interval is different from the cached
+value. In practice, the reconfiguration only happens on the first URB
+submitted for the endpoint.

+Subject: [PATCH] pinctrl-bcm2835: Add support for BCM2838
+
+GPIO configuration on BCM2838 is largely the same as BCM2835 except for
+the pull up/down configuration. The old mechanism has been replaced
+by new registers which don't require the fixed delay.
+
+Detect BCN2838 at run-time and use the new mechanism. Backwards
+compatibility for the device-tree configuration has been retained.

-Subject: [PATCH 503/806] BCM270X_DT: Add non-removable clone of mmc node
-
-non-removable is a boolean property, and as such can't be unset by an
-overlay if it is set in a base DTB. Until now the workaround for this
-problem has been for overlays to clone non-removable nodes without
-the offending property, but this involves a lot of unnecessary
-replication. Instead, add a clone of the mmc node with non-removable
-already set to the base DTB, selecting the required version using
-the status properties.

+
+The PM block that the wdt driver was binding to actually has multiple

-Subject: [PATCH 507/806] BCM270X_DT: Rename Pi Zero W DT files
-
-The downtream Pi Zero W dts file uses the digit 0, whereas upstream
-chose to spell it out - "zero-w". The firmware has, for a long time,
-looked for bcm2708-rpi-zero-w.dtb first before falling back to the
-numerical version. Therefore it is better to follow upstream and
-make the switch to "bcm2708-rpi-zero-w".
-
-At the same time, remove some overrides that duplicate values
-inherited from the shared .dtsi files.

+Date: Wed, 12 Dec 2018 15:51:48 -0800
+Subject: [PATCH] soc: bcm: bcm2835-pm: Add support for power domains
+ under a new binding.
+
+This provides a free software alternative to raspberrypi-power.c's
+firmware calls to manage power domains. It also exposes a reset line,
+where previously the vc4 driver had to try to force power off the
+domain in order to trigger a reset.

+ initialization.
+
+The clock driver may probe after ours and so we need to pass the
+-EPROBE_DEFER out. Fix the other error path while we're here.
+
+v2: Use dom->name instead of dom->gov as the flag for initialized
+ domains, since we aren't setting up a governor. Make sure to
+ clear ->clk when no clk is present in the DT.

+Subject: [PATCH] soc: bcm: bcm2835-pm: Add support for 2711.
+
+Without the actual power management part any more, there's a lot less
+to set up for V3D. We just need to clear the RSTN field for the power
+domain, and expose the reset controller for toggling it again.
+
+This is definitely incomplete -- the old ISP and H264 is in the old
+bridge, but since we have no consumers of it I've just done the
+minimum to get V3D working.

- to MMAL usec
-
-V4L2 uses nsecs, whilst MMAL uses usecs, but the code wasn't converting
-between them. This upsets video encode rate control.

+Subject: [PATCH] drm/v3d: Add a little debugfs entry for measuring the
+ core clock.
+
+This adds just enough performance counter support to measure the
+clock. We don't have linux kernel drivers for the clock driving the
+HW, and this was useful for determining that the V3D HW is running on
+a slow clock, not that the driver was slow.

+From: Eric Anholt <eric@anholt.net>
+Date: Wed, 28 Nov 2018 15:09:25 -0800
+Subject: [PATCH] drm/v3d: Add support for submitting jobs to the TFU.
+
+The TFU can copy from raster, UIF, and SAND input images to UIF output
+images, with optional mipmap generation. This will certainly be
+useful for media EGL image input, but is also useful immediately for
+mipmap generation without bogging the V3D core down.
+
+For now we only run the queue 1 job deep, and don't have any hang
+recovery (though I don't think we should need it, with TFU). Queuing
+multiple jobs in the HW will require synchronizing the YUV coefficient
+regs updates since they don't get FIFOed with the job.
+
+v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain
+ why TFU is AUTH, clarify the syncing docs, drop the unused TFU
+ interrupt regs (you're expected to use the hub's), don't take
+ &bo->base for NULL bos.
+v3: Fix a little whitespace alignment (noticed by checkpatch), rebase
+ on drm_sched_job_cleanup() changes.

-Subject: [PATCH 517/806] i2c: bcm2835: Model Divider in CCF
-
-Commit bebff81fb8b9216eb4fba22cf910553621ae3477 upstream.
-
-Model the I2C bus clock divider as a part of the Core Clock Framework.
-Primarily this removes the clk_get_rate() call from each transfer.
-This call causes problems for slave drivers that themselves have
-internal clock components that are controlled by an I2C interface.
-When the slave's internal clock component is prepared, the prepare
-lock is obtained, and it makes calls to the I2C subsystem to
-command the hardware to activate the clock. In order to perform
-the I2C transfer, this driver sets the divider, which requires
-it to get the parent clock rate, which it does with clk_get_rate().
-Unfortunately, this function will try to take the clock prepare
-lock, which is already held by the slave's internal clock calls
-creating a deadlock.
-
-Modeling the divider in the CCF natively removes this dependency
-and the divider value is only set upon changing the bus clock
-frequency or changes in the parent clock that cascade down to this
-divisor. This obviates the need to set the divider with every
-transfer and avoids the deadlock described above. It also should
-provide better clock debugging and save a few cycles on each
-transfer due to not having to recalcuate the divider value.

+Subject: [PATCH] drm/v3d: Add more tracepoints for V3D GPU rendering.
+
+The core scheduler tells us when the job is pushed to the scheduler's
+queue, and I had the job_run functions saying when they actually queue
+the job to the hardware. By adding tracepoints for the very top of
+the ioctls and the IRQs signaling job completion, "perf record -a -e
+v3d:.\* -e gpu_scheduler:.\* <job>; perf script" gets you a pretty
+decent timeline.

-
-It was covering part of the PM block's range, up to the WDT regs. To
-support the rest of the PM block's functionality, we need the full
-register range plus the AXI Async Bridge regs for PM sequencing.
-
-This doesn't convert any of the consumers over to the new binding yet,
-since we will need to be careful in coordinating our usage of firmware
-services that might power domains on and off versus the bcm2835-pm
-driver's access of those same domains.

+
+According to Dave, once you've started an L2T flush, all L2T accesses
+will be blocked until the flush completes. This fixes a consistent
+3-4ms stall between the ioctl and running the job, and 3DMMES Taiji
+goes from 27fps to 110fps.
+
+v2: Leave a note about why we don't need to wait for completion.

-Subject: [PATCH 526/806] Fix copy_from_user if BCM2835_FAST_MEMCPY=n
-
-The change which introduced CONFIG_BCM2835_FAST_MEMCPY unconditionally
-changed the behaviour of arm_copy_from_user. The page pinning code
-is not safe on ARMv7 if LPAE & high memory is enabled and causes
-crashes which look like PTE corruption.
-
-Make __copy_from_user_memcpy conditional on CONFIG_2835_FAST_MEMCPY=y
-which is really an ARMv6 / Pi1 optimization and not necessary on newer
-ARM processors.

-Subject: [PATCH 527/806] PCI: brcmstb: Add Broadcom STB PCIe host controller
- driver
-
-This commit adds the basic Broadcom STB PCIe controller. Missing is
-the ability to process MSI and also handle dma-ranges for inbound
-memory accesses. These two functionalities are added in subsequent
-commits.
-
-The PCIe block contains an MDIO interface. This is a local interface
-only accessible by the PCIe controller. It cannot be used or shared
-by any other HW. As such, the small amount of code for this
-controller is included in this driver as there is little upside to put
-it elsewhere.

-Subject: [PATCH 528/806] PCI: brcmstb: Add dma-range mapping for inbound
- traffic
-
-The Broadcom STB PCIe host controller is intimately related to the
-memory subsystem. This close relationship adds complexity to how cpu
-system memory is mapped to PCIe memory. Ideally, this mapping is an
-identity mapping, or an identity mapping off by a constant. Not so in
-this case.
-
-Consider the Broadcom reference board BCM97445LCC_4X8 which has 6 GB
-of system memory. Here is how the PCIe controller maps the
-system memory to PCIe memory:
-
- memc0-a@[ 0....3fffffff] <=> pci@[ 0....3fffffff]
- memc0-b@[100000000...13fffffff] <=> pci@[ 40000000....7fffffff]
- memc1-a@[ 40000000....7fffffff] <=> pci@[ 80000000....bfffffff]
- memc1-b@[300000000...33fffffff] <=> pci@[ c0000000....ffffffff]
- memc2-a@[ 80000000....bfffffff] <=> pci@[100000000...13fffffff]
- memc2-b@[c00000000...c3fffffff] <=> pci@[140000000...17fffffff]
-
-Although there are some "gaps" that can be added between the
-individual mappings by software, the permutation of memory regions for
-the most part is fixed by HW. The solution of having something close
-to an identity mapping is not possible.
-
-The idea behind this HW design is that the same PCIe module can
-act as an RC or EP, and if it acts as an EP it concatenates all
-of system memory into a BAR so anything can be accessed. Unfortunately,
-when the PCIe block is in the role of an RC it also presents this
-"BAR" to downstream PCIe devices, rather than offering an identity map
-between its system memory and PCIe space.
-
-Suppose that an endpoint driver allocs some DMA memory. Suppose this
-memory is located at 0x6000_0000, which is in the middle of memc1-a.
-The driver wants a dma_addr_t value that it can pass on to the EP to
-use. Without doing any custom mapping, the EP will use this value for
-DMA: the driver will get a dma_addr_t equal to 0x6000_0000. But this
-won't work; the device needs a dma_addr_t that reflects the PCIe space
-address, namely 0xa000_0000.
-
-So, essentially the solution to this problem must modify the
-dma_addr_t returned by the DMA routines routines. There are two
-ways (I know of) of doing this:
-
-(a) overriding/redefining the dma_to_phys() and phys_to_dma() calls
-that are used by the dma_ops routines. This is the approach of
-
- arch/mips/cavium-octeon/dma-octeon.c
-
-In ARM and ARM64 these two routines are defiend in asm/dma-mapping.h
-as static inline functions.
-
-(b) Subscribe to a notifier that notifies when a device is added to a
-bus. When this happens, set_dma_ops() can be called for the device.
-This method is mentioned in:
-
- http://lxr.free-electrons.com/source/drivers/of/platform.c?v=3.16#L152
-
-where it says as a comment
-
- "In case if platform code need to use own special DMA
- configuration, it can use Platform bus notifier and
- handle BUS_NOTIFY_ADD_DEVICE event to fix up DMA
- configuration."
-
-Solution (b) is what this commit does. It uses its own set of
-dma_ops which are wrappers around the arch_dma_ops. The
-wrappers translate the dma addresses before/after invoking
-the arch_dma_ops, as appropriate.

+Subject: [PATCH] drm/vc4: Disable V3D interactions if the v3d
+ component didn't probe.
+
+One might want to use the VC4 display stack without using Mesa.
+Similar to the debugfs fixes for not having all of the possible
+display bits enabled, make sure you can't oops in vc4 if v3d isn't
+enabled.

-Subject: [PATCH 529/806] PCI: brcmstb: Add MSI capability
-
-This commit adds MSI to the Broadcom STB PCIe host controller. It does
-not add MSIX since that functionality is not in the HW. The MSI
-controller is physically located within the PCIe block, however, there
-is no reason why the MSI controller could not be moved elsewhere in
-the future.
-
-Since the internal Brcmstb MSI controller is intertwined with the PCIe
-controller, it is not its own platform device but rather part of the
-PCIe platform device.

+Subject: [PATCH] drm/v3d: Add support for V3D v4.2.
+
+No compatible string for it yet, just the version-dependent changes.
+They've now tied the hub and the core interrupt lines into a single
+interrupt line coming out of the block. It also turns out I made a
+mistake in modeling the V3D v3.3 and v4.1 bridge as a part of V3D
+itself -- the bridge is going away in favor of an external reset
+controller in a larger HW module.
+
+v2: Use consistent checks for whether we're on 4.2, and fix a leak in
+ an error path.
+v3: Use more general means of determining if the current 4.2 changes
+ are in place, as apparently other platforms may switch back (noted
+ by Dave). Update the binding doc.

-+Brcmstb PCIe Host Controller Device Tree Bindings
-+
-+Required Properties:
-+- compatible
-+ "brcm,bcm7425-pcie" -- for 7425 family MIPS-based SOCs.
-+ "brcm,bcm7435-pcie" -- for 7435 family MIPS-based SOCs.
-+ "brcm,bcm7445-pcie" -- for 7445 and later ARM based SOCs (not including
-+ the 7278).
-+ "brcm,bcm7278-pcie" -- for 7278 family ARM-based SOCs.
-+
-+- reg -- the register start address and length for the PCIe reg block.
-+- interrupts -- two interrupts are specified; the first interrupt is for
-+ the PCI host controller and the second is for MSI if the built-in
-+ MSI controller is to be used.
-+- interrupt-names -- names of the interrupts (above): "pcie" and "msi".
-+- #address-cells -- set to <3>.
-+- #size-cells -- set to <2>.
-+- #interrupt-cells: set to <1>.
-+- interrupt-map-mask and interrupt-map, standard PCI properties to define the
-+ mapping of the PCIe interface to interrupt numbers.
-+- ranges: ranges for the PCI memory and I/O regions.
-+- linux,pci-domain -- should be unique per host controller.
-+
-+Optional Properties:
-+- clocks -- phandle of pcie clock.
-+- clock-names -- set to "sw_pcie" if clocks is used.
-+- dma-ranges -- Specifies the inbound memory mapping regions when
-+ an "identity map" is not possible.
-+- msi-controller -- this property is typically specified to have the
-+ PCIe controller use its internal MSI controller.
-+- msi-parent -- set to use an external MSI interrupt controller.
-+- brcm,enable-ssc -- (boolean) indicates usage of spread-spectrum clocking.
-+- max-link-speed -- (integer) indicates desired generation of link:
-+ 1 => 2.5 Gbps (gen1), 2 => 5.0 Gbps (gen2), 3 => 8.0 Gbps (gen3).
-+

+Subject: [PATCH] drm/v3d: HACK: gut runtime pm for now.
+
+Something is still unstable -- on starting a new glxgears from an idle
+X11, I get an MMU violation in high addresses. The CTS also failed
+quite quickly. With this, CTS progresses for an hour before OOMing
+(allocating some big buffers when my board only has 600MB available to
+Linux)

-Subject: [PATCH 537/806] thermal: brcmstb_thermal: Add BCM2838 support
-
-The BCM2838 has an AVS TMON hardware block. This adds the necessary
-support to the brcmstb_thermal driver ( no trip handling ).

+Subject: [PATCH] drm/v3d: Refactor job management.
+
+The CL submission had two jobs embedded in an exec struct. When I
+added TFU support, I had to replicate some of the exec stuff and some
+of the job stuff. As I went to add CSD, it became clear that actually
+what was in exec should just be in the two CL jobs, and it would let
+us share a lot more code between the 4 queues.

+Subject: [PATCH] drm/v3d: Add missing implicit synchronization.
+
+It is the expectation of existing userspace (X11 + Mesa, in
+particular) that jobs submitted to the kernel against a shared BO will
+get implicitly synchronized by their submission order. If we want to
+allow clever userspace to disable implicit synchronization, we should
+do that under its own submit flag (as amdgpu and lima do).
+
+Note that we currently only implicitly sync for the rendering pass,
+not binning -- if you texture-from-pixmap in the binning vertex shader
+(vertex coordinate generation), you'll miss out on synchronization.
+
+Fixes flickering when multiple clients are running in parallel,
+particularly GL apps and compositors.

+Subject: [PATCH] drm: vc4: Add an overlay plane to vc4-firmware-kms
+
+This uses a new API that is exposed via the mailbox service
+to stick an element straight on the screen using DispmanX.
+
+The primary and cursor planes have also been switched to using
+the new plane API, and it supports layering based on the DRM
+zpos parameter.

-Subject: [PATCH 545/806] dwc_otg: Choose appropriate IRQ handover strategy
-
-2711 has no MPHI peripheral, but the ARM Control block can fake
-interrupts. Use the size of the DTB "mphi" reg block to determine
-which is required.

-Subject: [PATCH 546/806] usb: xhci: Disable the XHCI 5 second timeout
-
-If the VL805 EEPROM has not been programmed then boot will hang for five
-seconds. The timeout seems to be arbitrary and is an unecessary
-delay on the first boot. Remove the timeout.
-
-This is common code and probably can't be upstreamed unless the timeout
-can be configurable somehow or perhaps the XHCI driver can be skipped
-on the first boot.

-interval has no effect.
-
-Add an explicit reconfiguration of the endpoint context when requested,

-Subject: [PATCH 549/806] pinctrl-bcm2835: Add support for BCM2838
-
-GPIO configuration on BCM2838 is largely the same as BCM2835 except for
-the pull up/down configuration. The old mechanism has been replaced
-by new registers which don't require the fixed delay.
-
-Detect BCN2838 at run-time and use the new mechanism. Backwards
-compatibility for the device-tree configuration has been retained.

-
-The PM block that the wdt driver was binding to actually has multiple
-features we want to expose (power domains, reset, watchdog). Move the
-DT attachment to a MFD driver and make WDT probe against MFD.

-Subject: [PATCH 554/806] soc: bcm: bcm2835-pm: Add support for power domains
- under a new binding.
-
-This provides a free software alternative to raspberrypi-power.c's
-firmware calls to manage power domains. It also exposes a reset line,
-where previously the vc4 driver had to try to force power off the
-domain in order to trigger a reset.

-Subject: [PATCH 557/806] soc: bcm: bcm2835-pm: Add support for 2711.
-
-Without the actual power management part any more, there's a lot less
-to set up for V3D. We just need to clear the RSTN field for the power
-domain, and expose the reset controller for toggling it again.
-
-This is definitely incomplete -- the old ISP and H264 is in the old
-bridge, but since we have no consumers of it I've just done the
-minimum to get V3D working.

-
-This adds just enough performance counter support to measure the
-clock. We don't have linux kernel drivers for the clock driving the
-HW, and this was useful for determining that the V3D HW is running on
-a slow clock, not that the driver was slow.

+Subject: [PATCH] drm/v3d: Add support for compute shader dispatch.
+
+The compute shader dispatch interface is pretty simple -- just pass in
+the regs that userspace has passed us, with no CLs to run. However,
+with no CL to run it means that we need to do manual cache flushing of
+the L2 after the HW execution completes (for SSBO, atomic, and
+image_load_store writes that are the output of compute shaders).
+
+This doesn't yet expose the L2 cache's ability to have a region of the
+address space not write back to memory (which could be used for
+shared_var storage).
+
+So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing
+the ES31 tests), and on the kernel side on 7278 (failing atomic
+compswap tests in a way that doesn't reproduce on simpenrose).
+
+v2: Fix excessive allocation for the clean_job (reported by Dan
+ Carpenter). Keep refs on jobs until clean_job is finished, to
+ avoid spurious MMU errors if the output BOs are freed by userspace
+ before L2 cleaning is finished.

-Subject: [PATCH 563/806] drm/v3d: Add support for submitting jobs to the TFU.
-
-The TFU can copy from raster, UIF, and SAND input images to UIF output
-images, with optional mipmap generation. This will certainly be
-useful for media EGL image input, but is also useful immediately for
-mipmap generation without bogging the V3D core down.
-
-For now we only run the queue 1 job deep, and don't have any hang
-recovery (though I don't think we should need it, with TFU). Queuing
-multiple jobs in the HW will require synchronizing the YUV coefficient
-regs updates since they don't get FIFOed with the job.
-
-v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain
- why TFU is AUTH, clarify the syncing docs, drop the unused TFU
- interrupt regs (you're expected to use the hub's), don't take
- &bo->base for NULL bos.
-v3: Fix a little whitespace alignment (noticed by checkpatch), rebase
- on drm_sched_job_cleanup() changes.

+ support.
+
+The overscan support was required for the old mailbox API
+in order to match up the cursor and frame buffer planes.
+With the newer API directly talking to dispmanx there is no
+difference, therefore FKMS does not need to make any
+adjustments.

-Subject: [PATCH 566/806] drm/v3d: Add more tracepoints for V3D GPU rendering.
-
-The core scheduler tells us when the job is pushed to the scheduler's
-queue, and I had the job_run functions saying when they actually queue
-the job to the hardware. By adding tracepoints for the very top of
-the ioctls and the IRQs signaling job completion, "perf record -a -e
-v3d:.\* -e gpu_scheduler:.\* <job>; perf script" gets you a pretty
-decent timeline.

-Subject: [PATCH 569/806] drm/v3d: Drop the wait for L2T flush to complete.
-
-According to Dave, once you've started an L2T flush, all L2T accesses
-will be blocked until the flush completes. This fixes a consistent
-3-4ms stall between the ioctl and running the job, and 3DMMES Taiji
-goes from 27fps to 110fps.
-
-v2: Leave a note about why we don't need to wait for completion.

+Subject: [PATCH] drm/vc4: Max resolution of 7680 is conditional on
+ being Pi4
+
+The max resolution had been increased from 2048 to 7680 for all
+platforms. This code is common with Pi0-3 which have a max render
+target for GL of 2048, therefore the increased resolution has to
+be conditional on the platform.
+Switch based on whether the bcm2835-v3d node is found, as that is
+not present on Pi4. (There is a potential configuration on Pi0-3
+with no v3d, but this is very unlikely).

-Subject: [PATCH 576/806] drm/v3d: Add support for V3D v4.2.
-
-No compatible string for it yet, just the version-dependent changes.
-They've now tied the hub and the core interrupt lines into a single
-interrupt line coming out of the block. It also turns out I made a
-mistake in modeling the V3D v3.3 and v4.1 bridge as a part of V3D
-itself -- the bridge is going away in favor of an external reset
-controller in a larger HW module.
-
-v2: Use consistent checks for whether we're on 4.2, and fix a leak in
- an error path.
-v3: Use more general means of determining if the current 4.2 changes
- are in place, as apparently other platforms may switch back (noted
- by Dave). Update the binding doc.

+Subject: [PATCH] staging: vc-sm-cma: Add in allocation for VPU
+ requests.
+
+Module has to change from tristate to bool as all CMA functions
+are boolean.

+ * and taking some code for CMA/dmabuf handling from the Android Ion
+ * driver (Google/Linaro).
+ *
+- * This is cut down version to only support import of dma_bufs from
+- * other kernel drivers. A more complete implementation of the old
+- * vmcs_sm functionality can follow later.
+ *
++ * This driver has 3 main uses:
++ * 1) Allocating buffers for the kernel or userspace that can be shared with the
++ * VPU.
++ * 2) Importing dmabufs from elsewhere for sharing with the VPU.
++ * 3) Allocating buffers for use by the VPU.
++ *
++ * In the first and second cases the native handle is a dmabuf. Releasing the
++ * resource inherently comes from releasing the dmabuf, and this will trigger
++ * unmapping on the VPU. The underlying allocation and our buffer structure are
++ * retained until the VPU has confirmed that it has finished with it.
++ *
++ * For the VPU allocations the VPU is responsible for triggering the release,
++ * and therefore the released message decrements the dma_buf refcount (with the
++ * VPU mapping having already been marked as released).

-Subject: [PATCH 577/806] drm/v3d: Don't try to set OVRTMUOUT on V3D 4.x.
-
-The old field is gone and the register now has a different field,
-QRMAXCNT for how many TMU requests get serviced before thread switch.
-We were accidentally reducing it from its default of 0x3 (4 requests)
-to 0x0 (1).
-
-v2: Skip setting the reg at all on 4.x, instead of trying to update
- only the old field.

+Subject: [PATCH] staging: vc-sm-cma: Add in userspace allocation API
+
+Replacing the functionality from the older vc-sm driver,
+add in a userspace API that allows allocation of buffers,
+and importing of dma-bufs.
+The driver hands out dma-buf fds, therefore much of the
+handling around lifespan and odd mmaps from the old driver
+goes away.

+Subject: [PATCH] staging: vcsm-cma: Fixup the alloc code handling of
+ kernel_id
+
+The allocation code had been copied in from an old branch prior
+to having added the IDR for 64bit support. It was therefore pushing
+a pointer into the kernel_id field instead of an IDR handle, the
+lookup therefore failed, and we never released the buffer.

-Subject: [PATCH 584/806] drm/v3d: Rename the fence signaled from IRQs to
- "irq_fence".
-
-We have another thing called the "done fence" that tracks when the
-scheduler considers the job done, and having the shared name was
-confusing.

-Date: Thu, 27 Dec 2018 12:11:52 -0800
-Subject: [PATCH 585/806] drm/v3d: Refactor job management.
-
-The CL submission had two jobs embedded in an exec struct. When I
-added TFU support, I had to replicate some of the exec stuff and some
-of the job stuff. As I went to add CSD, it became clear that actually
-what was in exec should just be in the two CL jobs, and it would let
-us share a lot more code between the 4 queues.

-particular) that jobs submitted to the kernel against a shared BO will
-get implicitly synchronized by their submission order. If we want to
-allow clever userspace to disable implicit synchronization, we should
-do that under its own submit flag (as amdgpu and lima do).
-
-Note that we currently only implicitly sync for the rendering pass,
-not binning -- if you texture-from-pixmap in the binning vertex shader
-(vertex coordinate generation), you'll miss out on synchronization.
-
-Fixes flickering when multiple clients are running in parallel,
-particularly GL apps and compositors.

-Subject: [PATCH 588/806] drm/vc4: Make sure that vblank waits work without v3d
- loaded.
-
-This flag exists to protect legacy drivers, but when vc4's v3d doesn't
-probe, it doesn't get set up by vc4_v3d.c's call of drm_irq_install.
-This resulted in applications running as fast as possible, and laggy
-performance from compton as it had to wait for the latest rendering by
-the application for its presentation.

+Subject: [PATCH] overlays: Add the spi-gpio40-45 overlay
+
+The 2711 B0 boot EEPROM is programmed via SPI0 on GPIO
+pins 40-43 CS0. Add a device tree overlay to optionally
+change the SPI0 pinmux from the external GPIO pins to
+the boot EEPROM pins.

-
-This should technically not expose VC4_T_TILED on pi4. However, if we
-don't expose anything, then userspace will assume that display can
-handle whatever modifiers 3d can do (UIF on 2711). By exposing a
-list, that will get intersected with what 3D can do so that we get T
-tiling for display on 2710 and linear on 2711.

-
-The core doesn't expect a false return from the scanoutpos function in
-normal usage, so we were doing the precise vblank timestamping path
-and thus "immediate" vblank disables (even though firmwarekms can't
-actually disable vblanks interrupts, sigh), and the kernel would get
-confused when getting timestamp info when also turning vblanks back
-on.

-Subject: [PATCH 592/806] drm: vc4: Add an overlay plane to vc4-firmware-kms
-
-This uses a new API that is exposed via the mailbox service
-to stick an element straight on the screen using DispmanX.
-
-The primary and cursor planes have also been switched to using
-the new plane API, and it supports layering based on the DRM
-zpos parameter.

+Subject: [PATCH] bcm2835-dma: Add proper 40-bit DMA support
+
+The 40-bit additions are not fully tested, but it should be
+capable of supporting both 40-bit memcpy on BCM2711 and regular
+Lite channels on BCM2835.

+Subject: [PATCH] usb: add plumbing for updating interrupt endpoint
+ interval state
+
+xHCI caches device and endpoint data after the interface is configured,
+so an explicit command needs to be issued for any device driver wanting
+to alter the polling interval of an endpoint.
+
+Add usb_fixup_endpoint() to allow drivers to do this. The fixup must be
+called after calculating endpoint bandwidth requirements but before any
+URBs are submitted.
+
+If polling intervals are shortened, any bandwidth reservations are no
+longer valid but in practice polling intervals are only ever relaxed.
+
+Limit the scope to interrupt transfers for now.

+Subject: [PATCH] drm: vc4: Add status of which display is updated
+ through vblank
+
+Previously multiple displays were slaved off the same SMI
+interrupt, triggered by HVS channel 1 (HDMI0).
+This doesn't work if you only have a DPI or DSI screen (HVS channel
+0), and gives slightly erroneous results with dual HDMI as the
+events for HDMI1 are incorrect.
+
+Use SMIDSW0 and SMIDSW1 registers to denote which display has
+triggered the vblank.
+Handling should be backwards compatible with older firmware.

-Subject: [PATCH 609/806] drm/v3d: Add support for compute shader dispatch.
-
-The compute shader dispatch interface is pretty simple -- just pass in
-the regs that userspace has passed us, with no CLs to run. However,
-with no CL to run it means that we need to do manual cache flushing of
-the L2 after the HW execution completes (for SSBO, atomic, and
-image_load_store writes that are the output of compute shaders).
-
-This doesn't yet expose the L2 cache's ability to have a region of the
-address space not write back to memory (which could be used for
-shared_var storage).
-
-So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing
-the ES31 tests), and on the kernel side on 7278 (failing atomic
-compswap tests in a way that doesn't reproduce on simpenrose).
-
-v2: Fix excessive allocation for the clean_job (reported by Dan
- Carpenter). Keep refs on jobs until clean_job is finished, to
- avoid spurious MMU errors if the output BOs are freed by userspace
- before L2 cleaning is finished.

+Date: Tue, 4 Jun 2019 16:22:22 +0100
+Subject: [PATCH] arm: dts: Improve the bcm27xx inclusion hierarchy
+
+1) The top-level .dts files now include parallel chains of bcm27xx.dtsi
+ and bcm27xx-rpi.dtsi files, with no cross-inclusion between the two
+ chains.
+
+2) Move definitions and deletions to the point of maximum commonality
+ to reduce redundancy.

+ read, select it again
+
+commit 3856032a0628e6b94badb9131a706dda185e071d upstream.
+
+The protocol is not allowing to obtain a byte of 0xff for PIO_ACCESS_READ
+call. It is very likely that the slave was not addressed properly and
+it is just not respoding (leaving the bus in logic high state) during
+the read of sampled PIO value.
+We cannot just call w1_reset_resume_command() because the problem will
+persist, instead try selecting (addressing) the slave again.

-Subject: [PATCH 621/806] drm/vc4: Max resolution of 7680 is conditional on
- being Pi4
-
-The max resolution had been increased from 2048 to 7680 for all
-platforms. This code is common with Pi0-3 which have a max render
-target for GL of 2048, therefore the increased resolution has to
-be conditional on the platform.
-Switch based on whether the bcm2835-v3d node is found, as that is
-not present on Pi4. (There is a potential configuration on Pi0-3
-with no v3d, but this is very unlikely).

- * and taking some code for CMA/dmabuf handling from the Android Ion
- * driver (Google/Linaro).
- *
-- * This is cut down version to only support import of dma_bufs from
-- * other kernel drivers. A more complete implementation of the old
-- * vmcs_sm functionality can follow later.
- *
-+ * This driver has 3 main uses:
-+ * 1) Allocating buffers for the kernel or userspace that can be shared with the
-+ * VPU.
-+ * 2) Importing dmabufs from elsewhere for sharing with the VPU.
-+ * 3) Allocating buffers for use by the VPU.
-+ *
-+ * In the first and second cases the native handle is a dmabuf. Releasing the
-+ * resource inherently comes from releasing the dmabuf, and this will trigger
-+ * unmapping on the VPU. The underlying allocation and our buffer structure are
-+ * retained until the VPU has confirmed that it has finished with it.
-+ *
-+ * For the VPU allocations the VPU is responsible for triggering the release,
-+ * and therefore the released message decrements the dma_buf refcount (with the
-+ * VPU mapping having already been marked as released).

+Subject: [PATCH] overlays: Correct gpio-fan gpio flags for 4.19
+
+The gpio-fan overlay was submitted for the 4.14 kernel where the second
+value in the Device Tree gpios declaration was ignored (thanks to an
+old-style driver), allowing the fan-control output to be active-high
+even though the declaration appears to request it be active-low.
+The gpio-fan driver in 4.19 uses GPIO descriptors and honours the
+active-low flag that the overlay (accidentally?) supplies.
+
+Change/correct the flags field to mark the GPIO as active-high.

-
-Replacing the functionality from the older vc-sm driver,
-add in a userspace API that allows allocation of buffers,
-and importing of dma-bufs.
-The driver hands out dma-buf fds, therefore much of the
-handling around lifespan and odd mmaps from the old driver

+Subject: [PATCH] staging: vcsm-cma: Remove cache manipulation ioctl
+ from ARM64
+
+The cache flushing ioctls are used by the Pi3 HEVC hw-assisted
+decoder as it needs finer grained flushing control than dma_ops
+allow.
+These cache calls are not present for ARM64, therefore disable
+them. We are not actively supporting 64bit kernels at present,
+and the use case of the HEVC decoder is fairly limited.

+Due to a misunderstanding of the DMA mapping APIs, I made

-Subject: [PATCH 629/806] staging: vcsm-cma: Fixup the alloc code handling of
- kernel_id
-
-The allocation code had been copied in from an old branch prior
-to having added the IDR for 64bit support. It was therefore pushing
-a pointer into the kernel_id field instead of an IDR handle, the
-lookup therefore failed, and we never released the buffer.

+Subject: [PATCH] media: vb2: set reqbufs/create_bufs capabilities
+
+Upstream commit e5079cf11373e4cc98be8b1072aece429eb2d4d2.
+
+Set the capabilities field of v4l2_requestbuffers and v4l2_create_buffers.
+
+The various mapping modes were easy, but for signaling the request capability
+a new 'supports_requests' bitfield was added to videobuf2-core.h (and set in
+vim2m and vivid). Drivers have to set this bitfield for any queue where
+requests are supported.

+Subject: [PATCH] media: vb2: Allow reqbufs(0) with "in use" MMAP
+ buffers
+
+Upstream commit d644cca50f366cd109845ae92e37c09ed79adf81
+
+Videobuf2 presently does not allow VIDIOC_REQBUFS to destroy outstanding
+buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are
+considered "in use". This is different behavior than for other memory
+types and prevents us from deallocating buffers in following two cases:
+
+1) There are outstanding mmap()ed views on the buffer. However even if
+ we put the buffer in reqbufs(0), there will be remaining references,
+ due to vma .open/close() adjusting vb2 buffer refcount appropriately.
+ This means that the buffer will be in fact freed only when the last
+ mmap()ed view is unmapped.
+
+2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer
+ is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF
+ get and decremented on DMABUF release. This means that the buffer
+ will be alive until all importers release it.
+
+Considering both cases above, there does not seem to be any need to
+prevent reqbufs(0) operation, because buffer lifetime is already
+properly managed by both mmap() and DMABUF code paths. Let's remove it
+and allow userspace freeing the queue (and potentially allocating a new
+one) even though old buffers might be still in processing.
+
+To let userspace know that the kernel now supports orphaning buffers
+that are still in use, add a new V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS
+to be set by reqbufs and create_bufs.
+

+ updated documentation, and added back debug message]

+Subject: [PATCH] overlays: Add real parameters to the rpi-poe overlay
+
+As a result of being loaded by the POE HAT EEPROM, the rpi-poe overlay
+doesn't expose parameters in the usual way; instead it adds them to
+the base Device Tree, and the user is expected to use "dtparam=..."
+to access them.
+
+To make the documentation correct and to protect users who load the
+overlay explicitly, expecting to be able to use the parameters, add
+real parameters to the overlay as well.

+Subject: [PATCH] overlays: Rename pi3- overlays to be less
+ model-specific (#3052)
+
+Rename the various pi3- overlays to be more generic, listing
+the devices they apply to in the README. The original names are
+retained for backwards compatibility as files that just include
+the new versions - the README marks them as being deprecated.

+Commit 4a5cfa39465cad25dd736d7ceba8a5d32eea4ecc upstream.
+
+If any of the clock code in the probe fails and returns, the IRQ
+will not be freed. Moving the IRQ request to last allows it to
+be freed on any errors further up in the probe function. devm_
+calls can apparently not be used because there are some potential
+race conditions that will arise.

+Commit 9de93b04df16b055824e3f1f13fedb90fbcf2e4f upstream.
+
+Probe function fails to recognize that upstream clock actually
+doesn't yet exist because clock driver has not been initialized.
+Actually try to go get the clock and test for its existence
+before trying to set up a downstream clock based upon it.
+
+This fixes a bug that causes the i2c driver not to work with
+monolithic kernels.

+Subject: [PATCH] overlays: i2c-gpio: Fix the "bus" parameter
+
+The "bus" parameter has two functions - providing unique names for
+multiple instances of the overlay, and allowing the number of the bus
+(i.e. "i2c-<bus>") to be specified. The second function hasn't worked
+as intended because the overlay doesn't include a "reg" property and
+the firmware intentionally won't create a "reg" property if one doesn't
+already exist.
+
+Allow the bus numbering scheme to work as intended by providing a "reg"
+with a default value that means "the next available one".

+Subject: [PATCH] tty: amba-pl011: Make TX optimisation conditional
+
+pl011_tx_chars takes a "from_irq" parameter to reduce the number of
+register accesses. When from_irq is true the function assumes that the
+FIFO is half empty and writes up to half a FIFO's worth of bytes
+without polling the FIFO status register, the reasoning being that
+the function is being called as a result of the TX interrupt being
+raised. This logic would work were it not for the fact that
+pl011_rx_chars, called from pl011_int before pl011_tx_chars, releases
+the spinlock before calling tty_flip_buffer_push.
+
+A user thread writing to the UART claims the spinlock and ultimately
+calls pl011_tx_chars with from_irq set to false. This reverts to the
+older logic that polls the FIFO status register before sending every
+byte. If this happen on an SMP system during the section of the IRQ
+handler where the spinlock has been released, then by the time the TX
+interrupt handler is called, the FIFO may already be full, and any
+further writes are likely to be lost.
+
+The fix involves adding a per-port flag that is true iff running from
+within the interrupt handler and the spinlock has not yet been released.
+This flag is then used as the value for the from_irq parameter of
+pl011_tx_chars, causing polling to be used in the unsafe case.

+Subject: [PATCH] xhci: add quirk for host controllers that don't
+ update endpoint DCS
+
+Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints
+at least, if the xHC halts on a particular TRB due to an error then
+the DCS field in the Out Endpoint Context maintained by the hardware
+is not updated with the current cycle state.
+
+Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit
+from the TRB that the xHC stopped on.

+
+The BCM2835 I2C blocks have a register to set the clock-stretch
+timeout - how long the device is allowed to hold SCL low - in bus
+cycles. The current driver doesn't write to the register, therefore
+the default value of 64 cycles is being used for all devices.
+
+Set the timeout to the value recommended for SMBus - 35ms.

-Subject: [PATCH 643/806] bcm2835-dma: Add proper 40-bit DMA support
-
-The 40-bit additions are not fully tested, but it should be
-capable of supporting both 40-bit memcpy on BCM2711 and regular
-Lite channels on BCM2835.

+Subject: [PATCH] overlays: dpi18 and dpi24 vc4 compatibility
+
+The dpi overlays use the fb device tree node as a place to hang the
+necessary pinctrl changes. With one of the VC4 overlays loaded, the
+fb node is disabled so the changes have no effect.
+
+Modify the overlays to also use the vc4 node, to cover both use
+cases.

+Subject: [PATCH] overlays: Add i2c0 and i2c1 for regularity
+
+The new i2c overlays for pi4 (i2c3, i2c4, i2c5, i2c6) have a
+standardised interface that allows pin groups to be chosen
+atomically rather than as individual pins. Add i2c0 and i2c1
+overlays to fit the naming scheme and parameter usage, deprecating
+i2c0-bcm2708 and i2c1-bcm2708.

+Commit 6c4f52dca36f5e3e2354c30591d38e92f4657ed9 upstream.
+
+TV margins properties can only be added as part of the SDTV TV
+connector properties creation, but we might need those props for HDMI
+TVs too, so let's move the margins props creation in a separate
+function and expose it to drivers.
+
+We also add an helper to attach margins props to a connector.

+Subject: [PATCH] drm/vc4: Take margin setup into account when updating
+ planes
+
+Commit 666e73587f90f42d90385c1bea1009a650bf73f4 upstream.
+
+Applyin margins is just a matter of scaling all planes appropriately
+and adjusting the CRTC X/Y offset to account for the
+left/right/top/bottom borders.
+
+Create a vc4_plane_margins_adj() function doing that and call it from
+vc4_plane_setup_clipping_and_scaling() so that we are ready to attach
+margins properties to the HDMI connector.

-Subject: [PATCH 653/806] usb: add plumbing for updating interrupt endpoint
- interval state
-
-xHCI caches device and endpoint data after the interface is configured,
-so an explicit command needs to be issued for any device driver wanting
-to alter the polling interval of an endpoint.
-
-Add usb_fixup_endpoint() to allow drivers to do this. The fixup must be
-called after calculating endpoint bandwidth requirements but before any
-URBs are submitted.
-
-If polling intervals are shortened, any bandwidth reservations are no
-longer valid but in practice polling intervals are only ever relaxed.
-
-Limit the scope to interrupt transfers for now.

+
+Commit db999538fdb0679629d90652f8a1437df1e85a7d upstream.
+
+Now that the plane code takes the margins setup into account, we can
+safely attach margin props to the HDMI connector.
+
+We also take care of filling AVI infoframes correctly to expose the
+top/botton/left/right bar.
+
+Note that those margin props match pretty well the
+overscan_{left,right,top,bottom} properties defined in config.txt and
+parsed by the VC4 firmware.

-
-Previously multiple displays were slaved off the same SMI

-This doesn't work if you only have a DPI or DSI screen (HVS channel
-0), and gives slightly erroneous results with dual HDMI as the
-events for HDMI1 are incorrect.
-
-Use SMIDSW0 and SMIDSW1 registers to denote which display has
-triggered the vblank.

++ (The default behaviour is that the Digital

++ gain. For most users, this will be desired
++ as it will prevent clipping. By appending
++ the 24dB_digital_gain parameter, the Digital
++ volume control will allow up to 24dB of
++ gain. If this parameter is enabled, it is the
++ responsibility of the user to ensure that
++ the Digital volume control is set to a value

-Subject: [PATCH 663/806] arm: dts: Improve the bcm27xx inclusion hierarchy
-
-1) The top-level .dts files now include parallel chains of bcm27xx.dtsi
- and bcm27xx-rpi.dtsi files, with no cross-inclusion between the two
- chains.
-
-2) Move definitions and deletions to the point of maximum commonality
- to reduce redundancy.

-Kernels since 4.19 have required the correct manufacture name in the

-Dallas/Maxim DS1307 should have been "dallas,ds1307" and not
-"maxim,ds1307".

+
+These wireless mouse/keyboard combo remote control devices specify
+multiple "wheel" events in their report descriptors. The wheel events
+are incorrectly defined and apparently map to accelerometer data, leading
+to spurious mouse scroll events being generated at an extreme rate when

+
+As a workaround, use HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE to mask

+
+Some HDMI monitors do not abide by the full or limited
+(16-235) range RGB flags in the AVI infoframe. This can
+result in images looking washed out (if given limited and
+interpreting as full), or detail disappearing at the extremes
+(given full and interpreting as limited).

+property ("Broadcast RGB") to force one mode or the other.

-The ds2805 has a structure named: w1_family_2d, which surely

+Rewrite the command line parser in order to get away from the state machine

+
+Hopefully, this will allow to extend it more easily to support named modes

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 3aeeb13d899627fe2b86bdbdcd0927cf7192234f upstream.
+Minor conflict resolution as upstream has moved functions
+from drm_fb_helper.c to a new drm_client_modeset.c
+
+The drm subsystem also uses the video= kernel parameter, and in the
+documentation refers to the fbdev documentation for that parameter.
+
+However, that documentation also says that instead of giving the mode using
+its resolution we can also give a name. However, DRM doesn't handle that
+case at the moment. Even though in most case it shouldn't make any
+difference, it might be useful for analog modes, where different standards
+might have the same resolution, but still have a few different parameters
+that are not encoded in the modes (NTSC vs NTSC-J vs PAL-M for example).

-commit c50d09a86172073f55ebac0b92ad5a75907d64e7 upstream.
-
-The state_read() was calling PIO_ACCESS_READ once and bail out if it
-failed for this first time.
-This commit is improving this to trying more times before it give up,
-similarly as the write call is currently doing.

+Subject: [PATCH] drm/modes: Allow to specify rotation and reflection
+ on the commandline
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Commit 1bf4e09227c345e246062285eba4b8fe660e512e upstream.
+Minor conflict resolution as upstream has moved functions
+from drm_fb_helper.c to a new drm_client_modeset.c
+
+Rotations and reflections setup are needed in some scenarios to initialise
+properly the initial framebuffer. Some drivers already had a bunch of
+quirks to deal with this, such as either a private kernel command line
+parameter (omapdss) or on the device tree (various panels).
+
+In order to accomodate this, let's create a video mode parameter to deal
+with the rotation and reflexion.

-
-commit 3856032a0628e6b94badb9131a706dda185e071d upstream.
-
-The protocol is not allowing to obtain a byte of 0xff for PIO_ACCESS_READ
-call. It is very likely that the slave was not addressed properly and
-it is just not respoding (leaving the bus in logic high state) during
-the read of sampled PIO value.
-We cannot just call w1_reset_resume_command() because the problem will
-persist, instead try selecting (addressing) the slave again.

+The TV margins has been defined as a structure inside the

+Properly configuring the overscan properties might be needed for the

+Let's allow for more properties on the kernel command line to setup each

+
+Commit 731514b446fe6748d5a55a3dff202efb45c7d8df upstream.
+Reworked as functions have been moved from drm_atomic_helper.[c|h]
+to drm_atomic_state_helper.[c|h].
+
+During the connector reset, if that connector has a TV property, it needs
+to be reset to the value provided on the command line.
+
+Provide a helper to do that.

+
+Taken from the dri-devel mailing list (11/7/2019) to fixup the cmdline
+parsing, but requires changes as things have moved between 4.19 and 5.2.
+
+From: Dmitry Osipenko <digetx@gmail.com>
+
+The rotation mode from cmdline shouldn't be taken into account if it
+wasn't specified in the cmdline. This fixes ignored default display
+orientation when display mode is given using cmdline without the
+rotation being specified.

-
-Downstream Raspberry Pi dts files add "coherent_pool=1M" to the kernel
-command line to aid the dwc_otg driver, but this excluded Pi 4 which
-uses a new XCHI interface instead. UAS also benefits from a larger
-coherent_pool value, so replicate the addition in bcm2711-rpi-4-b.dts.

+Subject: [PATCH] staging: bcm2835-codec: switch to multi-planar API
+
+There are two APIs for mem2mem devices, the older single-planar API and
+the newer multi-planar one. Without making things overly complex, the
+driver can only support one or the other. However the userspace libv4l2
+library has a plugin that allows multi-planar API devices to service
+single-planar consumers.
+
+Chromium supports the multi-planar API exclusively, though this is
+currently limited to ChromiumOS. It would be possible to add support
+for generic Linux.
+
+Switching to the multi-planar API would allow usage of both APIs from
+userspace.

+Subject: [PATCH] staging: bcm2835-codec: implement
+ V4L2_CID_MIN_BUFFERS_FOR_CAPTURE
+
+The stateful decoder specification shows an optional step for retrieving
+the miminum number of capture buffers required for the decoder to
+proceed. While not a required parameter, having it makes some
+applications happy.
+
+bcm2835-codec is a little different from other decoder implementations
+in that there is an intermediate format conversion between the hardware
+and V4L2 buffers. The number of capture buffers required is therefore
+independent of the stream and DPB etc.
+
+There are plans to remove the conversion, but it requires a fair amount
+of rework within the firmware. Until that is done, simply return a value
+of 1.

+Instead of filling in the struct v4l2_capability device_caps

+
+That way the V4L2 core knows what the capabilities of the

+

-Subject: [PATCH 682/806] overlays: Correct gpio-fan gpio flags for 4.19
-
-The gpio-fan overlay was submitted for the 4.14 kernel where the second
-value in the Device Tree gpios declaration was ignored (thanks to an
-old-style driver), allowing the fan-control output to be active-high
-even though the declaration appears to request it be active-low.
-The gpio-fan driver in 4.19 uses GPIO descriptors and honours the
-active-low flag that the overlay (accidentally?) supplies.
-
-Change/correct the flags field to mark the GPIO as active-high.

-Subject: [PATCH 683/806] staging: vcsm-cma: Remove cache manipulation ioctl
- from ARM64
-
-The cache flushing ioctls are used by the Pi3 HEVC hw-assisted
-decoder as it needs finer grained flushing control than dma_ops
-allow.
-These cache calls are not present for ARM64, therefore disable
-them. We are not actively supporting 64bit kernels at present,
-and the use case of the HEVC decoder is fairly limited.

-
-Due to a misunderstanding of the DMA mapping APIs, I made
-the wrong decision on how to implement this.
-
-Rework to use dma_alloc_coherent instead of the CMA
-API. This also allows it to be built as a module easily.

+Subject: [PATCH] net: bcmgenet: Workaround #2 for Pi4 Ethernet fail
+
+Some combinations of Pi 4Bs and Ethernet switches don't reliably get a
+DCHP-assigned IP address, leaving the unit with a self=assigned 169.254
+address. In the failure case, the Pi is left able to receive packets
+but not send them, suggesting that the MAC<->PHY link is getting into
+a bad state.
+
+It has been found empirically that skipping a reset step by the genet
+driver prevents the failures. No downsides have been discovered yet,
+and unlike the forced renegotiation it doesn't increase the time to
+get an IP address, so the workaround is enabled by default; add
+

+
+drm_atomic_helper_check_plane_state() takes care of checking the
+scaling capabilities and calculating the clipped X/Y offsets for us.
+
+Rely on this function instead of open-coding the logic.
+
+Incidentally, it seems to fix a problem we had with negative X/Y

-Upstream commit e5079cf11373e4cc98be8b1072aece429eb2d4d2.
-
-Set the capabilities field of v4l2_requestbuffers and v4l2_create_buffers.
-
-The various mapping modes were easy, but for signaling the request capability
-a new 'supports_requests' bitfield was added to videobuf2-core.h (and set in
-vim2m and vivid). Drivers have to set this bitfield for any queue where
-requests are supported.

-Subject: [PATCH 692/806] media: vb2: Allow reqbufs(0) with "in use" MMAP
- buffers
-
-Upstream commit d644cca50f366cd109845ae92e37c09ed79adf81
-
-Videobuf2 presently does not allow VIDIOC_REQBUFS to destroy outstanding
-buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are
-considered "in use". This is different behavior than for other memory
-types and prevents us from deallocating buffers in following two cases:
-
-1) There are outstanding mmap()ed views on the buffer. However even if
- we put the buffer in reqbufs(0), there will be remaining references,
- due to vma .open/close() adjusting vb2 buffer refcount appropriately.
- This means that the buffer will be in fact freed only when the last
- mmap()ed view is unmapped.
-
-2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer
- is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF
- get and decremented on DMABUF release. This means that the buffer
- will be alive until all importers release it.
-
-Considering both cases above, there does not seem to be any need to
-prevent reqbufs(0) operation, because buffer lifetime is already
-properly managed by both mmap() and DMABUF code paths. Let's remove it
-and allow userspace freeing the queue (and potentially allocating a new
-one) even though old buffers might be still in processing.
-
-To let userspace know that the kernel now supports orphaning buffers
-that are still in use, add a new V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS
-to be set by reqbufs and create_bufs.
-
-[p.zabel@pengutronix.de: added V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS,
- updated documentation, and added back debug message]

-Subject: [PATCH 694/806] overlays: Rename pi3- overlays to be less
- model-specific (#3052)
-
-Rename the various pi3- overlays to be more generic, listing
-the devices they apply to in the README. The original names are
-retained for backwards compatibility as files that just include
-the new versions - the README marks them as being deprecated.
-
-See: https://github.com/raspberrypi/firmware/issues/1174

- probe
-
-Commit 4a5cfa39465cad25dd736d7ceba8a5d32eea4ecc upstream.
-
-If any of the clock code in the probe fails and returns, the IRQ
-will not be freed. Moving the IRQ request to last allows it to
-be freed on any errors further up in the probe function. devm_
-calls can apparently not be used because there are some potential
-race conditions that will arise.

-
-Commit 9de93b04df16b055824e3f1f13fedb90fbcf2e4f upstream.
-
-Probe function fails to recognize that upstream clock actually
-doesn't yet exist because clock driver has not been initialized.
-Actually try to go get the clock and test for its existence
-before trying to set up a downstream clock based upon it.
-
-This fixes a bug that causes the i2c driver not to work with
-monolithic kernels.

+Subject: [PATCH] xhci: Use more event ring segment table entries
+
+Users have reported log spam created by "Event Ring Full" xHC event
+TRBs. These are caused by interrupt latency in conjunction with a very
+busy set of devices on the bus. The errors are benign, but throughput
+will suffer as the xHC will pause processing of transfers until the
+event ring is drained by the kernel. Expand the number of event TRB slots
+available by increasing the number of event ring segments in the ERST.
+
+Controllers have a hardware-defined limit as to the number of ERST
+entries they can process, so make the actual number in use
+min(ERST_MAX_SEGS, hw_max).

+Subject: [PATCH] dwc_otg: use align_buf for small IN control transfers
+ (#3150)
+
+The hardware will do a 4-byte write to memory on any IN packet received
+that is between 1 and 3 bytes long. This tramples memory in the uvcvideo
+driver, as it uses a sequence of 1- and 2-byte control transfers to
+query the min/max/range/step of each individual camera control and
+gives us buffers that are offsets into a struct.
+
+Catch small control transfers in the data phase and use the align_buf
+to bounce the correct number of bytes into the URB's buffer.
+
+In general, short packets on non-control endpoints should be OK as URBs
+should have enough buffer space for a wMaxPacket size transfer.
+

-
-The "bus" parameter has two functions - providing unique names for
-multiple instances of the overlay, and allowing the number of the bus
-(i.e. "i2c-<bus>") to be specified. The second function hasn't worked
-as intended because the overlay doesn't include a "reg" property and
-the firmware intentionally won't create a "reg" property if one doesn't
-already exist.
-
-Allow the bus numbering scheme to work as intended by providing a "reg"
-with a default value that means "the next available one".

-Subject: [PATCH 698/806] tty: amba-pl011: Make TX optimisation conditional
-
-pl011_tx_chars takes a "from_irq" parameter to reduce the number of
-register accesses. When from_irq is true the function assumes that the
-FIFO is half empty and writes up to half a FIFO's worth of bytes
-without polling the FIFO status register, the reasoning being that
-the function is being called as a result of the TX interrupt being
-raised. This logic would work were it not for the fact that
-pl011_rx_chars, called from pl011_int before pl011_tx_chars, releases
-the spinlock before calling tty_flip_buffer_push.
-
-A user thread writing to the UART claims the spinlock and ultimately
-calls pl011_tx_chars with from_irq set to false. This reverts to the
-older logic that polls the FIFO status register before sending every
-byte. If this happen on an SMP system during the section of the IRQ
-handler where the spinlock has been released, then by the time the TX
-interrupt handler is called, the FIFO may already be full, and any
-further writes are likely to be lost.
-
-The fix involves adding a per-port flag that is true iff running from
-within the interrupt handler and the spinlock has not yet been released.
-This flag is then used as the value for the from_irq parameter of
-pl011_tx_chars, causing polling to be used in the unsafe case.
-
-Fixes: 1e84d22322ce ("serial/amba-pl011: Refactor and simplify TX FIFO handling")

- update endpoint DCS
-
-Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints
-at least, if the xHC halts on a particular TRB due to an error then
-the DCS field in the Out Endpoint Context maintained by the hardware
-is not updated with the current cycle state.
-
-Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit
-from the TRB that the xHC stopped on.

-
-The BCM2835 I2C blocks have a register to set the clock-stretch
-timeout - how long the device is allowed to hold SCL low - in bus
-cycles. The current driver doesn't write to the register, therefore
-the default value of 64 cycles is being used for all devices.
-
-Set the timeout to the value recommended for SMBus - 35ms.

-
-The dpi overlays use the fb device tree node as a place to hang the
-necessary pinctrl changes. With one of the VC4 overlays loaded, the
-fb node is disabled so the changes have no effect.
-
-Modify the overlays to also use the vc4 node, to cover both use
-cases.

-
-The new i2c overlays for pi4 (i2c3, i2c4, i2c5, i2c6) have a
-standardised interface that allows pin groups to be chosen
-atomically rather than as individual pins. Add i2c0 and i2c1
-overlays to fit the naming scheme and parameter usage, deprecating
-i2c0-bcm2708 and i2c1-bcm2708.

++* Sony 1/4.0-Inch 8Mpixel CMOS Digital Image Sensor
++
++The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor with
++an active array size of 3280H x 2464V. It is programmable through I2C
++interface. The I2C address is fixed to 0x10 as per sensor data sheet.
++Image data is sent through MIPI CSI-2, which is configured as either 2 or 4
++data lanes.
++
++Required Properties:
++- compatible: value should be "sony,imx219" for imx219 sensor
++- reg: I2C bus address of the device
++- clocks: reference to the xclk input clock.
++- clock-names: should be "xclk".
++- DOVDD-supply: Digital I/O voltage supply, 1.8 volts
++- AVDD-supply: Analog voltage supply, 2.8 volts
++- DVDD-supply: Digital core voltage supply, 1.2 volts
++
++Optional Properties:
++- xclr-gpios: reference to the GPIO connected to the xclr pin, if any. Must be
++ released after all supplies are applied.
++ This is an active high signal to the imx219.
++
++The imx219 device node should contain one 'port' child node with
++an 'endpoint' subnode. For further reading on port node refer to
++Documentation/devicetree/bindings/media/video-interfaces.txt.
++
++Endpoint node required properties for CSI-2 connection are:
++- remote-endpoint: a phandle to the bus receiver's endpoint node.
++- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
++- data-lanes: should be set to <1 2>, or <1 2 3 4> (two or four lane CSI-2
++ supported)
++
++Example:
++ sensor@10 {
++ compatible = "sony,imx219";
++ reg = <0x10>;
++ #address-cells = <1>;
++ #size-cells = <0>;
++ clocks = <&imx219_clk>;
++ clock-names = "xclk";
++ xclr-gpios = <&gpio_sensor 0 0>;
++ DOVDD-supply = <&vgen4_reg>; /* 1.8v */
++ AVDD-supply = <&vgen3_reg>; /* 2.8v */
++ DVDD-supply = <&vgen2_reg>; /* 1.2v */
++
++ imx219_clk: camera-clk {
++ compatible = "fixed-clock";
++ #clock-cells = <0>;
++ clock-frequency = <24000000>;
++ };
++
++ port {
++ sensor_out: endpoint {
++ remote-endpoint = <&csiss_in>;
++ clock-lanes = <0>;
++ data-lanes = <1 2>;
++ };
++ };
++ };

+
+Adds a driver for the 8MPix Sony IMX219 CSI2 sensor.
+Whilst the sensor supports 2 or 4 CSI2 data lanes, this driver
+currently only supports 2 lanes.
+8MPix @ 15fps, 1080P @ 30fps (cropped FOV), and 1640x1232 (2x2 binned)
+@ 30fps are currently supported.

+Subject: [PATCH] staging: bcm2835-codec: Add role to device name
+
+Three entities are created, Decode, Encode and ISP but all of the video
+nodes use the same video name string "bcm2835-codec" which makes it
+difficult to identify each role.
+
+Append the role-name to the video name to facilitate identifying a
+specific instance from userspace.
+
+The Card-Type is also extended with the role name to support identifying
+the device context from within QUERY_CAP operations.

-
-Commit 6c4f52dca36f5e3e2354c30591d38e92f4657ed9 upstream.
-
-TV margins properties can only be added as part of the SDTV TV
-connector properties creation, but we might need those props for HDMI
-TVs too, so let's move the margins props creation in a separate
-function and expose it to drivers.
-
-We also add an helper to attach margins props to a connector.

-Subject: [PATCH 716/806] drm/vc4: Take margin setup into account when updating
- planes
-
-Commit 666e73587f90f42d90385c1bea1009a650bf73f4 upstream.
-
-Applyin margins is just a matter of scaling all planes appropriately
-and adjusting the CRTC X/Y offset to account for the
-left/right/top/bottom borders.
-
-Create a vc4_plane_margins_adj() function doing that and call it from
-vc4_plane_setup_clipping_and_scaling() so that we are ready to attach
-margins properties to the HDMI connector.

-
-Commit db999538fdb0679629d90652f8a1437df1e85a7d upstream.
-
-Now that the plane code takes the margins setup into account, we can
-safely attach margin props to the HDMI connector.
-
-We also take care of filling AVI infoframes correctly to expose the
-top/botton/left/right bar.
-
-Note that those margin props match pretty well the
-overscan_{left,right,top,bottom} properties defined in config.txt and
-parsed by the VC4 firmware.

+Subject: [PATCH] regulator/gpio: Allow nonexclusive GPIO access
+
+commit b0ce7b29bfcd090ddba476f45a75ec0a797b048a upstream.
+
+[ This is a partial cherry-pick, omitting the regulator
+change which isn't required ]
+
+This allows nonexclusive (simultaneous) access to a single
+GPIO line for the fixed regulator enable line. This happens
+when several regulators use the same GPIO for enabling and
+disabling a regulator, and all need a handle on their GPIO
+descriptor.
+
+This solution with a special flag is not entirely elegant
+and should ideally be replaced by something more careful as
+this makes it possible for several consumers to
+enable/disable the same GPIO line to the left and right
+without any consistency. The current use inside the regulator
+core should however be fine as it takes special care to
+handle this.
+
+For the state of the GPIO backend, this is still the
+lesser evil compared to going back to global GPIO
+numbers.

- and MX3
-
-These wireless mouse/keyboard combo remote control devices specify
-multiple "wheel" events in their report descriptors. The wheel events
-are incorrectly defined and apparently map to accelerometer data, leading
-to spurious mouse scroll events being generated at an extreme rate when
-the device is moved.
-
-As a workaround, use HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE to mask
-feeding the extra wheel events to the input subsystem.

-Subject: [PATCH 731/806] drm/vc4: Add "Broadcast RGB" connector property
-
-Some HDMI monitors do not abide by the full or limited
-(16-235) range RGB flags in the AVI infoframe. This can
-result in images looking washed out (if given limited and
-interpreting as full), or detail disappearing at the extremes
-(given full and interpreting as limited).
-
-Copy the Intel i915 driver's approach of adding an override
-property ("Broadcast RGB") to force one mode or the other.

-Subject: [PATCH 733/806] drm/modes: Rewrite the command line parser
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-commit e08ab74bd4c7a5fe311bc05f32dbb4f1e7fa3428 upstream.
-
-Rewrite the command line parser in order to get away from the state machine
-parsing the video mode lines.
-
-Hopefully, this will allow to extend it more easily to support named modes
-and / or properties set directly on the command line.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-commit 3aeeb13d899627fe2b86bdbdcd0927cf7192234f upstream.
-Minor conflict resolution as upstream has moved functions
-from drm_fb_helper.c to a new drm_client_modeset.c
-
-The drm subsystem also uses the video= kernel parameter, and in the
-documentation refers to the fbdev documentation for that parameter.
-
-However, that documentation also says that instead of giving the mode using
-its resolution we can also give a name. However, DRM doesn't handle that
-case at the moment. Even though in most case it shouldn't make any
-difference, it might be useful for analog modes, where different standards
-might have the same resolution, but still have a few different parameters
-that are not encoded in the modes (NTSC vs NTSC-J vs PAL-M for example).

-Commit 1bf4e09227c345e246062285eba4b8fe660e512e upstream.
-Minor conflict resolution as upstream has moved functions
-from drm_fb_helper.c to a new drm_client_modeset.c
-
-Rotations and reflections setup are needed in some scenarios to initialise
-properly the initial framebuffer. Some drivers already had a bunch of
-quirks to deal with this, such as either a private kernel command line
-parameter (omapdss) or on the device tree (various panels).
-
-In order to accomodate this, let's create a video mode parameter to deal
-with the rotation and reflexion.

-Subject: [PATCH 743/806] staging: bcm2835-codec: switch to multi-planar API
-
-There are two APIs for mem2mem devices, the older single-planar API and
-the newer multi-planar one. Without making things overly complex, the
-driver can only support one or the other. However the userspace libv4l2
-library has a plugin that allows multi-planar API devices to service
-single-planar consumers.
-
-Chromium supports the multi-planar API exclusively, though this is
-currently limited to ChromiumOS. It would be possible to add support
-for generic Linux.
-
-Switching to the multi-planar API would allow usage of both APIs from
-userspace.

-Subject: [PATCH 744/806] staging: bcm2835-codec: implement
- V4L2_CID_MIN_BUFFERS_FOR_CAPTURE
-
-The stateful decoder specification shows an optional step for retrieving
-the miminum number of capture buffers required for the decoder to
-proceed. While not a required parameter, having it makes some
-applications happy.
-
-bcm2835-codec is a little different from other decoder implementations
-in that there is an intermediate format conversion between the hardware
-and V4L2 buffers. The number of capture buffers required is therefore
-independent of the stream and DPB etc.
-
-There are plans to remove the conversion, but it requires a fair amount
-of rework within the firmware. Until that is done, simply return a value
-of 1.

- video_device
-
-Instead of filling in the struct v4l2_capability device_caps
-field, fill in the struct video_device device_caps field.
-
-That way the V4L2 core knows what the capabilities of the
-video device are.
-
-This is similar to a cleanup series by Hans Verkuil [1].

-
-The overlays for enabling the new BCM2711 I2C interfaces were lacking
-the means to configure the baud/clock rate.
-
-Also explictly set the default pins, rather than relying on the values
-in the base DTB.

-
-The details over when and how a driver is to service the
-vblank events are sketchy, and the fkms driver was triggering
-a kernel warning every time the crtc was enabled or disabled.
-
-Copy the event handling as used by the vc4-kms driver slightly
-more closely, and we avoid the warnings.

-Subject: [PATCH 755/806] net: bcmgenet: Workaround #2 for Pi4 Ethernet fail
-
-Some combinations of Pi 4Bs and Ethernet switches don't reliably get a
-DCHP-assigned IP address, leaving the unit with a self=assigned 169.254
-address. In the failure case, the Pi is left able to receive packets
-but not send them, suggesting that the MAC<->PHY link is getting into
-a bad state.
-
-It has been found empirically that skipping a reset step by the genet
-driver prevents the failures. No downsides have been discovered yet,
-and unlike the forced renegotiation it doesn't increase the time to
-get an IP address, so the workaround is enabled by default; add
-
- genet.skip_umac_reset=n
-
-to the command line to disable it.

- simplify the logic
-
-drm_atomic_helper_check_plane_state() takes care of checking the
-scaling capabilities and calculating the clipped X/Y offsets for us.
-
-Rely on this function instead of open-coding the logic.
-
-Incidentally, it seems to fix a problem we had with negative X/Y
-positioning of YUV planes.

-Subject: [PATCH 765/806] xhci: Use more event ring segment table entries
-
-Users have reported log spam created by "Event Ring Full" xHC event
-TRBs. These are caused by interrupt latency in conjunction with a very
-busy set of devices on the bus. The errors are benign, but throughput
-will suffer as the xHC will pause processing of transfers until the
-event ring is drained by the kernel. Expand the number of event TRB slots
-available by increasing the number of event ring segments in the ERST.
-
-Controllers have a hardware-defined limit as to the number of ERST
-entries they can process, so make the actual number in use
-min(ERST_MAX_SEGS, hw_max).

-Subject: [PATCH 766/806] dwc_otg: use align_buf for small IN control transfers
- (#3150)
-
-The hardware will do a 4-byte write to memory on any IN packet received
-that is between 1 and 3 bytes long. This tramples memory in the uvcvideo
-driver, as it uses a sequence of 1- and 2-byte control transfers to
-query the min/max/range/step of each individual camera control and
-gives us buffers that are offsets into a struct.
-
-Catch small control transfers in the data phase and use the align_buf
-to bounce the correct number of bytes into the URB's buffer.
-
-In general, short packets on non-control endpoints should be OK as URBs
-should have enough buffer space for a wMaxPacket size transfer.
-
-See: https://github.com/raspberrypi/linux/issues/3148

-+* Sony 1/4.0-Inch 8Mpixel CMOS Digital Image Sensor
-+
-+The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor with
-+an active array size of 3280H x 2464V. It is programmable through I2C
-+interface. The I2C address is fixed to 0x10 as per sensor data sheet.
-+Image data is sent through MIPI CSI-2, which is configured as either 2 or 4
-+data lanes.
-+
-+Required Properties:
-+- compatible: value should be "sony,imx219" for imx219 sensor
-+- reg: I2C bus address of the device
-+- clocks: reference to the xclk input clock.
-+- clock-names: should be "xclk".
-+- DOVDD-supply: Digital I/O voltage supply, 1.8 volts
-+- AVDD-supply: Analog voltage supply, 2.8 volts
-+- DVDD-supply: Digital core voltage supply, 1.2 volts
-+
-+Optional Properties:
-+- xclr-gpios: reference to the GPIO connected to the xclr pin, if any. Must be
-+ released after all supplies are applied.
-+ This is an active high signal to the imx219.
-+
-+The imx219 device node should contain one 'port' child node with
-+an 'endpoint' subnode. For further reading on port node refer to
-+Documentation/devicetree/bindings/media/video-interfaces.txt.
-+
-+Endpoint node required properties for CSI-2 connection are:
-+- remote-endpoint: a phandle to the bus receiver's endpoint node.
-+- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
-+- data-lanes: should be set to <1 2>, or <1 2 3 4> (two or four lane CSI-2
-+ supported)
-+
-+Example:
-+ sensor@10 {
-+ compatible = "sony,imx219";
-+ reg = <0x10>;
-+ #address-cells = <1>;
-+ #size-cells = <0>;
-+ clocks = <&imx219_clk>;
-+ clock-names = "xclk";
-+ xclr-gpios = <&gpio_sensor 0 0>;
-+ DOVDD-supply = <&vgen4_reg>; /* 1.8v */
-+ AVDD-supply = <&vgen3_reg>; /* 2.8v */
-+ DVDD-supply = <&vgen2_reg>; /* 1.2v */
-+
-+ imx219_clk: camera-clk {
-+ compatible = "fixed-clock";
-+ #clock-cells = <0>;
-+ clock-frequency = <24000000>;
-+ };
-+
-+ port {
-+ sensor_out: endpoint {
-+ remote-endpoint = <&csiss_in>;
-+ clock-lanes = <0>;
-+ data-lanes = <1 2>;
-+ };
-+ };
-+ };

-
-Adds a driver for the 8MPix Sony IMX219 CSI2 sensor.
-Whilst the sensor supports 2 or 4 CSI2 data lanes, this driver
-currently only supports 2 lanes.
-8MPix @ 15fps, 1080P @ 30fps (cropped FOV), and 1640x1232 (2x2 binned)
-@ 30fps are currently supported.

-Subject: [PATCH 802/806] regulator/gpio: Allow nonexclusive GPIO access
-
-commit b0ce7b29bfcd090ddba476f45a75ec0a797b048a upstream.
-
-[ This is a partial cherry-pick, omitting the regulator
-change which isn't required ]
-
-This allows nonexclusive (simultaneous) access to a single
-GPIO line for the fixed regulator enable line. This happens
-when several regulators use the same GPIO for enabling and
-disabling a regulator, and all need a handle on their GPIO
-descriptor.
-
-This solution with a special flag is not entirely elegant
-and should ideally be replaced by something more careful as
-this makes it possible for several consumers to
-enable/disable the same GPIO line to the left and right
-without any consistency. The current use inside the regulator
-core should however be fine as it takes special care to
-handle this.
-
-For the state of the GPIO backend, this is still the
-lesser evil compared to going back to global GPIO
-numbers.
-

-Subject: [PATCH 803/806] gpio: Enable nonexclusive gpiods from DT nodes
-
-commit ec757001c818c175e6b610e8ef80c2a25d1ed1a5 upstream.
-
-This makes gpiod_get_from_of_node() respect the
-GPIOD_FLAGS_BIT_NONEXCLUSIVE flag which is especially
-nice when getting regulator GPIOs right out of device
-tree nodes.
-
-Suggested-by: Marek Szyprowski <m.szyprowski@samsung.com>
-Fixes: b0ce7b29bfcd ("regulator/gpio: Allow nonexclusive GPIO access")

-Subject: [PATCH 804/806] Fix poll rate on touchscreen (#3238)
-
-Was running at 25Hz, rather than he expected 60. Only been doing it
-for the last 5 years....
-
-Replace msleep_interruptible with usleep_range as the msleep call
-is not accurate for times < 20ms.
