-From: Marcel Holtmann <marcel@holtmann.org>
-Date: Wed, 22 May 2019 09:05:40 +0200
-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.
-
-Fixes: d5bb334a8e17 ("Bluetooth: Align minimum encryption key size for LE and BR/EDR connections")
-Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

-From ae10c15867d9a5b85eefaf11333bd30473af4b2b Mon Sep 17 00:00:00 2001
-From: Phil Elwell <phil@raspberrypi.com>

-Subject: [PATCH] overlays: gpio-keys: Avoid open-drain warnings
-
-The i2c-gpio driver expects to use a GPIO in open-drain mode. Failure
-to configure it in that way causes alarming warnings in the kernel log.
-The BCM283x and BCM2711 GPIO blocks don't support open-drain mode,
-but i2c-gpio works anyway. Silence the warning by declaring that
-open-drain mode has been enabled by other means.
-
-See: https://github.com/raspberrypi/firmware/issues/1381

+
+The bytes per line numbers calculated by get_bytesperline was not

+(mostly by the calculate_pitch function there), resulting in failures

+
+Currently we call cec_phys_addr_invalidate on a hotplug deassert.
+That may be due to a TV power cycling, or an AVR being switched
+on (and switching edid). This makes CEC unusable.
+
+Set it back up again on the hotplug assert.

+Subject: [PATCH] snd_bcm2835: disable HDMI audio when vc4 is used
+ (#3640)
+
+Things don't work too well when both the vc4 driver and the firmware
+driver are trying to control the same audio output:
+
+[  763.569406] bcm2835_audio bcm2835_audio: vchi message timeout, msg=5
+
+Hence, when the vc4 HDMI driver is used, let it control audio. This is done
+by introducing a new device tree property to the audio node, and
+extending the vc4-kms-v3d overlays to set it appropriately.

+Subject: [PATCH] overlays: i2c-gpio: Avoid open-drain warnings
+
+The i2c-gpio driver expects to use a GPIO in open-drain mode. Failure
+to configure it in that way causes alarming warnings in the kernel log.
+The BCM283x and BCM2711 GPIO blocks don't support open-drain mode, but
+gpiolib can emulate it in software if configured correctly.
+
+Silence the warning by declaring the GPIOs as requiring open-drain
+mode, trusting gpiolib to manage the emulation. The previous
+incarnation of this patch took the other approach of telling the
+i2c-gpio driver that the GPIOs were configured for open-drain, but
+this had the effect of disabling the emulation. In some cases this
+appears to work, but examining the waveforms as analogue voltages
+shows contention, the success or failure depending on drive strengths.
+

+
+commit 92b8d2724464bc1d2e735a84c0da5741dce33485 upstream.
+
+Adding code comments to split code in dedicated parts. After the global
+declarations (defines, macros and function declarations), code is organized
+as follow :
+ - Device and family dependent structures and functions
+ - Interfaces functions
+ - Helpers functions
+ - Hardware functions
+ - Sysfs interface functions

+Subject: [PATCH] w1_therm: fix reset_select_slave during discovery
+
+commit c8ad65f6fbfdcb9b620674ef456020eef2bfeb36 upstream.
+
+Fix reset_select_slave issue during devices discovery by the master on
+bus. The w1_reset_select_slave() from w1_io.c, which was previously used,
+assume that if the slave count is 1 there is only one slave attached on
+the bus. This is not always true. For example when discovering devices,
+when the first device is discover by the bus master, its slave count is
+1, but some other slaves may be on the bus.
+
+In that case instead of adressing command to the attached slave the
+master throw a SKIP ROM command so that all slaves attached on the bus
+will answer simultenaously causing data collision.
+
+A dedicated reset_select_slave() function is implemented here,
+it always perform an adressing to each slave using the MATCH ROM
+command.

+Subject: [PATCH] w1_therm: adding ext_power sysfs entry
+
+commit b7bb6ca17a90f47c2fe2848531b5bbaf27a65ba7 upstream.
+
+Adding ext_power sysfs entry (RO). Return the power status of the device:
+ - 0: device parasite powered
+ - 1: device externally powered
+ - xx: xx is kernel error
+
+The power status of each device is check when the device is
+discover by the bus master, in 'w1_therm_add_slave(struct w1_slave *)'.
+The status is stored in the device structure w1_therm_family_data so
+that the driver always knows the power state of each device, which could
+be used later to determine the required strong pull up to apply on the
+line.
+
+The power status is re evaluate each time the sysfs ext_power read by
+a user.
+
+The hardware function 'read_powermode(struct w1_slave *sl)' act just as
+per device specifications, sending W1_READ_PSUPPLY command on the bus,
+and issue a read time slot, reading only one bit.
+
+A helper function 'bool bus_mutex_lock(struct mutex *lock)' is introduced.
+It try to aquire the bus mutex several times (W1_THERM_MAX_TRY), waiting
+W1_THERM_RETRY_DELAY between two attempt.
+
+Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

+Subject: [PATCH] w1_therm: adding resolution sysfs entry
+
+commit 308bdb94de0c1abe7eac5193f58638b8aeaddf4b upstream.
+
+Adding resolution sysfs entry (RW) to get or set the device resolution
+Write values are managed as follow:
+	* '9..12': resolution to set in bit
+	* Anything else: do nothing
+Read values are :
+	* '9..12': device resolution in bit
+	* '-xx': xx is kernel error when reading the resolution
+
+Only supported devices will show the sysfs entry. A new family has been
+created for DS18S20 devices as they do not implement resolution feature.
+
+The resolution of each device is check when the device is
+discover by the bus master, in 'w1_therm_add_slave(struct w1_slave *)'.
+The status is stored in the device structure w1_therm_family_data so
+that the driver always knows the resolution of each device, which could
+be used later to determine the required conversion duration (resolution
+dependent).
+
+The resolution is re evaluate each time a user read or write the sysfs
+entry.
+
+To avoid looping through the w1_therm_families at run time, the pointer
+'specific_functions' is set up to the correct 'w1_therm_family_converter'
+when the slave is added (which mean when it is discovered by the master).
+This initialization is done by a helper function
+'device_family(struct w1_slave *sl)', and a dedicated macro
+'SLAVE_SPECIFIC_FUNC(sl)' allow the access to the specific function of the
+slave device.
+
+'read_scratchpad' and 'write_scratchpad' are the hardware functions to
+access the device RAM, as per protocol specification.
+
+It cancel the former 'precision' functions, which was only set and never
+read (so not stored in the device struct).
+
+Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

+Subject: [PATCH] w1_therm: adding eeprom sysfs entry
+
+commit 45d457a4cf24455eefd076a01a3d86414fc2ff1e upstream.
+
+The driver implement 2 hardware functions to access device RAM:
+ * copy_scratchpad
+ * recall_scratchpad
+They act according to device specifications.
+
+As EEPROM operations are not device dependent (all w1_therm can perform
+EEPROM read/write operation following the same protocol), it is removed
+from device families structures.
+
+Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

+Subject: [PATCH] w1_therm: optimizing temperature read timings
+
+commit 67b392f7b8edfa6f427fecd98722acab34c1c99f upstream.
+
+Optimizing temperature reading by reducing waiting conversion time
+according to device resolution settings, as per device specification.
+This is device dependent as not all the devices supports resolution
+setting, so it has been added in device family structures.
+
+The process to read the temperature on the device has been adapted in a
+new function 'convert_t()', which replace the former 'read_therm()', is
+introduce to deal with this timing. Strong pull up is also applied during
+the required time, according to device power status needs and
+'strong_pullup' module parameter.
+
+'temperature_from_RAM()' function is introduced to get the correct
+temperature computation (device dependent) from device RAM data.
+
+An new sysfs entry has been added to ouptut only temperature. The old
+entry w1_slave has been kept for compatibility, without changing its
+output format.
+
+Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

+Subject: [PATCH] w1_therm: adding alarm sysfs entry
+
+commit e2c94d6f572079511945e64537eb1218643f2e68 upstream.
+
+Adding device alarms settings by a dedicated sysfs entry alarms (RW):
+read or write TH and TL in the device RAM. Checking devices in alarm
+state could be performed using the master search command.
+
+As alarms temperature level are store in a 8 bit register on the device
+and are signed values, a safe cast shall be performed using the min and
+max temperature that device are able to measure. This is done by
+int_to_short inline function.
+
+A 'write_data' field is added in the device structure, to bind the
+correct writing function, as some devices may have 2 or 3 bytes RAM.
+
+Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

++Description:
++		(RW) read or write TH and TL (Temperature High an Low) alarms.
++		Values shall be space separated and in the device range
++		(typical -55 degC to 125 degC), if not values will be trimmed
++		to device min/max capabilities. Values are integer as they are
++		stored in a 8bit register in the device. Lowest value is
++		automatically put to TL. Once set, alarms could be search at
++		master level, refer to Documentation/w1/w1_generic.rst for
++		detailed information
++Users:		any user space application which wants to communicate with
++		w1_term device

+Subject: [PATCH] w1_therm: adding bulk read support to trigger
+ multiple conversion on bus
+
+commit 57c76221d5af648c8355a55c09b050c5d8d38189 upstream.
+
+Adding bulk read support:
+Sending a 'trigger' command in the dedicated sysfs entry of bus master
+device send a conversion command for all the slaves on the bus. The sysfs
+entry is added as soon as at least one device supporting this feature
+is detected on the bus.
+
+The behavior of the sysfs reading temperature on the device is as follow:
+ * If no bulk read pending, trigger a conversion on the device, wait for
+ the conversion to be done, read the temperature in device RAM
+ * If a bulk read has been trigger, access directly the device RAM
+This behavior is the same on the 2 sysfs entries ('temperature' and
+'w1_slave').
+
+Reading the therm_bulk_read sysfs give the status of bulk operations:
+ * '-1': conversion in progress on at least 1 sensor
+ * '1': conversion complete but at least one sensor has not been read yet
+ * '0': no bulk operation. Reading temperature on ecah device will trigger
+a conversion
+
+As not all devices support bulk read feature, it has been added in device
+family structure.
+
+The attribute is set at master level as soon as a supporting device is
+discover. It is removed when the last supported device leave the bus.
+The count of supported device is kept with the static counter
+bulk_read_device_counter.
+
+A strong pull up is apply on the line if at least one device required it.
+The duration of the pull up is the max time required by a device on the
+line, which depends on the resolution settings of each device. The strong
+pull up could be adjust with the a module parameter.
+
+Updating documentation in Documentation/ABI/testing/sysfs-driver-w1_therm
+and Documentation/w1/slaves/w1_therm.rst accordingly.

+Subject: [PATCH] w1_therm: Free the correct variable
+
+commit e420637b81f78d0fbacf539bdb1b341eba602aea upstream.
+
+The problem is that we change "p_args" to point to the middle of the
+string so when we free it at the end of the function it's not freeing
+the same pointer that we originally allocated.

+
+commit f37d13d52c0560bd2bac40b22466af538e61a5ce upstream.
+
+The variable ret is being initialized with a value that is never read
+and it is being updated later with a new value. The initialization
+is redundant and can be removed.

+
+commit 22e21e51ce755399fd42055a3f668ee4af370881 upstream.
+
+While preparing the driver for upstream this detail was missed.
+
+If not asserted during the initialization process, devices connected on
+the bus will not be made aware of the internal reset happening. This,
+potentially resulting in unexpected behavior.

+Subject: [PATCH] clk: bcm: rpi: Add an enum for the firmware clocks
+
+While the firmware allows us to discover the available clocks, we need to
+discriminate those clocks to only register the ones meaningful to Linux.
+The firmware also doesn't provide a clock name, so having a list of the ID
+will help us to give clocks a proper name later on.

+Subject: [PATCH] clk: bcm: rpi: Use CCF boundaries instead of
+ rolling our own
+
+The raspberrypi firmware clock driver has a min_rate / max_rate clamping by
+storing the info it needs in a private structure.
+
+However, the CCF already provides such a facility, so we can switch to it
+to remove the boilerplate.

+The CPU clock has had so far a bunch of quirks to expose the clock tree
+properly, but since we reverted to exposing them through the MMIO driver,

+Subject: [PATCH] SQUASH: dts: Fix firmware clocks support
+
+Commit [1] touched a lot of files and still missed some platforms.
+In particular, Pi 2 was left with no clock scaling. Simplify the
+firmware clocks DTS support and extend it to all platforms that
+use the raspberrypi-cpufreq driver.

+Subject: [PATCH] PCI: brcmstb: Add DT property to control L1SS
+
+The BRCM PCIe block has controls to enable control of the CLKREQ#
+signal by the L1SS, and to gate the refclk with the CLKREQ# input.
+These controls are mutually exclusive - the upstream code sets the
+latter, but some use cases require the former.
+
+Add a Device Tree property - brcm,enable-l1ss - to switch to the
+L1SS configuration.

+Subject: [PATCH] media: irs1125: Atomic access to imager
+ reconfiguration
+
+Instead of changing the exposure and framerate settings for all sequences,
+they can be changed for every sequence individually now. Therefore the
+IRS1125_CID_SAFE_RECONFIG ctrl has been removed and replaced by
+IRS1125_CID_SAFE_RECONFIG_S<seq_num>_EXPO and *_FRAME ctrls.
+
+The consistency check in the sequence ctrl IRS1125_CID_SEQ_CONFIG
+is removed.

+Subject: [PATCH] media: irs1125: Keep HW in sync after imager reset
+
+When closing the video device, the irs1125 is put in power down state.
+To keep V4L2 ctrls and the HW in sync, v4l2_ctrl_handler_setup is
+called after power up.
+
+The compound ctrl IRS1125_CID_MOD_PLL however has a default value
+of all zeros, which puts the imager into a non responding state.
+Thus, this ctrl is not written by the driver into HW after power up.
+The userspace has to take care to write senseful data.

+Subject: [PATCH] staging: bcm2835-audio: Add missing MODULE_ALIAS
+
+Commit 8353fe6f1e0f ("Revert "staging: bcm2835-audio: Drop DT
+dependency"") reverts the upstream change and makes bcm2835-audio use
+device tree again, however, it also removes the MODULE_ALIAS for the
+platform device. This MODULE_ALIAS is needed, because VCHIQ registers
+bcm2835-audio as a child platform device since commit 25c7597af20d
+("staging: vchiq_arm: Register a platform device for audio"), and this
+mechanism is adopted also in the downstream kernel.
+
+This commit puts back that MODULE_ALIAS to make bcm2835-audio
+autoprobing work again. The rest of VCHIQ children have their
+MODULE_ALIASes in place.

+Upstream https://patchwork.linuxtv.org/patch/64669/
+
+Introduce two new pad operations to allow retrieving and configuring the
+media bus parameters on a subdevice pad.
+
+The newly introduced operations aims to replace the s/g_mbus_config video
+operations, which have been on their way for deprecation since a long

+Move the existing users of the g_mbus_config video operation to use the

+
+All the ported drivers report a static media bus configuration and do no

+Bridge drivers needs to call the new pad operation and will receive an
+-ENOICTLCMD when calling the old g_mbus_config video operation

+Subject: [PATCH]_mbus_config
+ ops
+
+Upstream https://patchwork.linuxtv.org/patch/64674/
+
+Use the new get_mbus_config and set_mbus_config pad operations in place
+of the video operations currently in use.
+
+Compared to other drivers where the same conversion has been performed,
+ov6650 proved to be a bit more tricky, as the existing g_mbus_config
+implementation did not report the currently applied configuration but
+the set of all possible configuration options.
+
+Adapt the driver to support the semantic of the two newly introduced
+operations:
+- get_mbus_config reports the current media bus configuration
+- set_mbus_config applies only changes explicitly requested and updates
+  the provided cfg parameter to report what has actually been applied to
+  the hardware.
+
+Compile-tested only.

+Subject: [PATCH] media: pxa_camera: Use the new set_mbus_config op
+
+Upstream https://patchwork.linuxtv.org/patch/64671/
+
+Move the PXA camera driver to use the new set_mbus_config pad operation.
+For this platform the change is not only cosmetic, as the pxa driver is
+currently the only driver in mainline to make use of the g_mbus_config
+and s_mbus_config video operations.
+
+The existing driver semantic is the following:
+- Collect all supported mbus config flags from the remote end
+- Match them with the supported PXA mbus configuration flags
+- If the remote subdevice allows multiple options for for VSYNC, HSYNC
+  and PCLK polarity, use platform data requested settings
+
+The semantic of the new get_mbus_config and set_mbus_config differs from
+the corresponding video ops, particularly in the fact get_mbus_config
+reports the current mbus configuration and not the set of supported
+configuration options, with set_mbus_config always reporting the actual
+mbus configuration applied to the remote subdevice.
+
+Adapt the driver to perform the following
+- Set the remote subdevice mbus configuration according to the PXA
+  platform data preferences.
+- If the applied configuration differs from the requested one (i.e. the
+  remote subdevice does not allow changing one setting) make sure that
+  - The remote end does not claim for DATA_ACTIVE_LOW, which seems not
+    supported by the platform
+  - The bus mastering roles match
+
+While at there remove a few checks performed on the media bus
+configuration at get_format() time as they do not belong there.
+
+Compile-tested only.

+MIME-Version: 1.0

+
+Upstream https://patchwork.linuxtv.org/patch/64673/
+
+When outputting SD-Core output through the TXA MIPI CSI-2 interface,
+the number of enabled data lanes should be reduced in order to guarantee
+that the two video formats produced by the SD-Core (480i and 576i)
+generate a MIPI CSI-2 link clock frequency compatible with the MIPI D-PHY
+specifications.
+
+Limit the number of enabled data lanes to 2, which is guaranteed to
+support 480i and 576i formats.
+
+Cache the number of enabled data lanes to be able to report it through
+the new get_mbus_config operation.

+the number of active data lanes accordingly.
+
+In order to be able to call the remote subdevice operation cache the
+index of the remote pad connected to the single CSI-2 input port.

+- * BCM2835 Unicam Capture Driver
+- *
+- * Copyright (C) 2017-2020 - Raspberry Pi (Trading) Ltd.
+- *
+- * Dave Stevenson <dave.stevenson@raspberrypi.com>
+- *
+- * Based on TI am437x driver by
+- *   Benoit Parrot <bparrot@ti.com>
+- *   Lad, Prabhakar <prabhakar.csengg@gmail.com>
+- *
+- * and TI CAL camera interface driver by
+- *    Benoit Parrot <bparrot@ti.com>
+- *
+- *
+- * 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 can 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. The driver will add both
+- * formats where the relevant formats are defined, and will automatically
+- * configure the repacking as required.
+- * Support for 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: bcm2835-unicam: Driver for CCP2/CSI2 camera
+ interface
+
+Add a driver for the Unicam camera receiver block on BCM283x processors.
+Compared to the bcm2835-camera driver present in staging, this driver
+handles the Unicam block only (CSI-2 receiver), and doesn't depend on
+the VC4 firmware running on the VPU.
+
+The commit is made up of a series of changes cherry-picked from the
+rpi-5.4.y branch of https://github.com/raspberrypi/linux/ with
+additional enhancements, forward-ported to the mainline kernel.

++ *
++ * Copyright (C) 2017-2020 - Raspberry Pi (Trading) Ltd.
++ *
++ * Dave Stevenson <dave.stevenson@raspberrypi.com>
++ *
++ * Based on TI am437x driver by
++ *   Benoit Parrot <bparrot@ti.com>
++ *   Lad, Prabhakar <prabhakar.csengg@gmail.com>
++ *
++ * and TI CAL camera interface driver by
++ *    Benoit Parrot <bparrot@ti.com>
++ *
++ *
++ * 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 can 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. The driver will add both
++ * formats where the relevant formats are defined, and will automatically
++ * configure the repacking as required.
++ * Support for 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: bcm2835-unicam: Always service interrupts
+
+From when bringing up the driver, there was a check in the isr
+to ignore interrupts (claiming them handled) should the driver
+not be streaming.
+
+The VPU now will not register a camera driver if it finds a
+CSI2 node enabled in device tree, therefore this flawed check is
+redundant.

+
+Since the unicam driver was modified to write to a dummy buffer when no
+user-supplied buffer is available, it can now write to and return a
+buffer even when there's only a single one. Enable this by changing the
+min_buffers_needed in the vb2_queue; it will be useful for enabling
+still captures without allocating more memory than absolutely necessary.

+Subject: [PATCH] dt/dtoverlays: Fix up base DT and overlays for
+ updated Unicam driver
+
+The upstreamed Unicam driver uses a dt property to denote how many
+lanes are supported by the receiver peripheral, independent of
+the number of lanes that the sensor wants to use. It also doesn't
+check the remote endpoint config for the number of lanes as that
+isn't the accepted way of doing things.
+
+Update the base DT for the brcm,num-data-lanes property, and the
+overlays to define the desired number of lanes at both ends of
+the link.

++* Sony IMX290 1/2.8-Inch CMOS Image Sensor
++
++The Sony IMX290 is a 1/2.8-Inch CMOS Solid-state image sensor with
++Square Pixel for Color Cameras. It is programmable through I2C and 4-wire
++interfaces. The sensor output is available via CMOS logic parallel SDR output,
++Low voltage LVDS DDR output and CSI-2 serial data output. The CSI-2 bus is the
++default. No bindings have been defined for the other busses.
++
++Required Properties:
++- compatible: Should be "sony,imx290"
++- reg: I2C bus address of the device
++- clocks: Reference to the xclk clock.
++- clock-names: Should be "xclk".
++- clock-frequency: Frequency of the xclk clock in Hz.
++- vdddo-supply: Sensor digital IO regulator.
++- vdda-supply: Sensor analog regulator.
++- vddd-supply: Sensor digital core regulator.
++
++Optional Properties:
++- reset-gpios: Sensor reset GPIO
++
++The imx290 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.
++
++Required Properties on endpoint:
++- data-lanes: check ../video-interfaces.txt
++- link-frequencies: check ../video-interfaces.txt
++- remote-endpoint: check ../video-interfaces.txt
++
++Example:
++	&i2c1 {
++		...
++		imx290: camera-sensor@1a {
++			compatible = "sony,imx290";
++			reg = <0x1a>;
++
++			reset-gpios = <&msmgpio 35 GPIO_ACTIVE_LOW>;
++			pinctrl-names = "default";
++			pinctrl-0 = <&camera_rear_default>;
++
++			clocks = <&gcc GCC_CAMSS_MCLK0_CLK>;
++			clock-names = "xclk";
++			clock-frequency = <37125000>;
++
++			vdddo-supply = <&camera_vdddo_1v8>;
++			vdda-supply = <&camera_vdda_2v8>;
++			vddd-supply = <&camera_vddd_1v5>;
++
++			port {
++				imx290_ep: endpoint {
++					data-lanes = <1 2 3 4>;
++					link-frequencies = /bits/ 64 <445500000>;
++					remote-endpoint = <&csiphy0_ep>;

+Subject: [PATCH] media: i2c: imx290: set the format before
+ VIDIOC_SUBDEV_G_FMT is called
+
+Commit d46cfdc86c30d5ec768924f0b1e2683c8d20b671 upstream.
+
+With the current driver 'media-ctl -p' issued right after the imx290 driver
+is loaded prints:
+pad0: Source
+             [fmt:unknown/0x0]
+
+The format value of zero is due to the current_format field of the imx290
+struct not being initialized yet.
+
+As imx290_entity_init_cfg() calls imx290_set_fmt(), the current_mode field
+is also initialized, so the line which set current_mode to a default value
+in driver's probe() function is no longer needed.

+ SET_RUNTIME_PM_OPS()
+
+Commit 8d2d1bedb1b9af3e0c039a4444858da7b6da71f8 upstream.
+
+The macro is defined as SET_RUNTIME_PM_OPS(suspend_fn, resume_fn, idle_fn),
+so imx290_power_off must be the 1st arg, and imx290_power_on the 2nd.

+Subject: [PATCH] media: i2c: imx290: fix reset GPIO pin handling
+
+Commit 3909a92d7df622b41b9ceeeea694e641cad7667b upstream.
+
+According to https://www.kernel.org/doc/Documentation/gpio/consumer.txt,
+
+- all of the gpiod_set_value_xxx() functions operate with the *logical*
+value. So in imx290_power_on() the reset signal should be cleared
+(de-asserted) with gpiod_set_value_cansleep(imx290->rst_gpio, 0), and in
+imx290_power_off() the value of 1 must be used to apply/assert the reset
+to the sensor. In the device tree the reset pin is described as
+GPIO_ACTIVE_LOW, and gpiod_set_value_xxx() functions take this into
+account,
+
+- when devm_gpiod_get_optional() is called with GPIOD_ASIS, the GPIO is
+not initialized, and the direction must be set later; using a GPIO
+without setting its direction first is illegal and will result in undefined
+behavior. Fix this by using GPIOD_OUT_HIGH instead of GPIOD_ASIS (this
+asserts the reset signal to the sensor initially).

+
+Commit 97589ad61c730e0f486635c6c19fa25ab8e8f29d upstream.
+
+The IMX290 sensor can output frames with 2/4 CSI2 data lanes. This commit
+adds support for 2 lane mode in addition to the 4 lane and also
+configuring the data lane settings in the driver based on system
+configuration.

+Subject: [PATCH] media: i2c: imx290: Add configurable link frequency
+ and pixel rate
+
+Commit 98e0500eadb772e1be32d8e369fcc3b7bcac93ed upstream.
+
+IMX290 operates with multiple link frequency and pixel rate combinations.
+The initial driver used a single setting for both but since we now have
+the lane count support in place, let's add configurable link frequency
+and pixel rate.

+
+Commit c566ac01ceaa02450acc155201772c0623530e76 upstream.
+
+IMX290 is capable of outputting frames in both Raw Bayer (packed) 10 and
+12 bit formats. Since the driver already supports RAW10 mode, let's add
+the missing RAW12 mode as well.

+
+Commit a270675875829b6d46eb9e38960fd6019555ebb8 upstream.
+
+The bus_type field of v4l2_fwnode_endpoint structure passed as the argument
+to v4l2_fwnode_endpoint_alloc_parse() function must be initiaized.
+Set it to V4L2_MBUS_CSI2_DPHY, and check for -ENXIO which is returned
+when the requested media bus type doesn't match the fwnode.
+
+Also remove v4l2_fwnode_endpoint field from struct imx290 as it is only
+needed in the probe function: use the local variable for this purpose.

+Subject: [PATCH] media: i2c: imx290: Correct range for V4L2_CID_GAIN
+ to 0-238
+
+The datasheet lists the gain as being 0.0 to 72.0dB in 0.3dB steps, which
+makes 238 steps total.
+Correct the 0-72 range defined in the driver.

+Subject: [PATCH] media: i2c: imx290: Add support for V4L2_CID_VBLANK
+
+In order to calculate framerate and durations userspace needs
+the vertical blanking information. This can be configurable,
+and indeed the datasheet lists different values for VBLANK for
+the 1080p and 720p modes.
+
+Add the new control, and adopt the datasheet values for each mode.

+This sensor does NOT change the Bayer order when changing the

+ imx290_write_buffered_reg
+
+imx290_set_hmax was using two independent writes to set up hmax,
+when all other multi-register writes were using imx290_write_buffered_reg
+which claims the group hold first.
+
+Switch imx290_set_hmax to using imx290_write_buffered_reg too.

+Subject: [PATCH] vc4_hdmi: Set HD_CTL_WHOLSMP and HD_CTL_CHALIGN_SET
+
+Symptom is random switching of speakers when using multichannel.
+
+Repeatedly running speakertest -c8 occasionally starts with
+channels jumbled. This is fixed with HD_CTL_WHOLSMP.
+
+The other bit looks beneficial and apears harmless in testing so
+I'd suggest adding it too.
+
+Documentation says: HD_CTL_WHILSMP_SET
+Wait for whole sample. When this bit is set MAI transmit will start
+only when there is at least one whole sample available in the fifo.
+
+Documentation says: HD_CTL_CHALIGN_SET
+Channel Align When Overflow. This bit is used to realign the audio channels in case of an overflow.
+If this bit is set, after the detection of an overflow, equal amount of dummy words to the missing
+words will be written to fifo, filling up the broken sample and maintaining alignment.

+Subject: [PATCH] ARM: dts: Add Bluetooth nodes for Raspberry Pi
+
+Add device tree nodes for Bluetooth on supported Raspberry Pi boards.
+It's disabled by default and can be enabled by `krnbt=on` dtparam. It's
+an alternative way of configuring Bluetooth, as compared to hciattach or
+btattach. When the dtparam is enabled, the Bluetooth driver is probed
+automatically and doesn't require any additional bring-up scripts.
+
+Note that Raspberry Pi 3 B rev 1.2 doesn't have the required hardware
+flow control pins of UART0 connected to the Bluetooth module, so the
+user should decrease the baudrate by passing `krnbt_baudrate=921600`
+dtparam to make it more stable. It resembles the behavior of the btuart
+script from Raspbian.
+
+The miniuart-bt overlay was modified to support Bluetooth probing with
+device tree, too. It's disabled by default and can be enabled by
+`krnbt=on` parameter of the miniuart-bt overlay.

+Having checked the firmware handling for interlaced modes,
+it appears to be possible to support interlaced modes on
+HDMI without adverse side effects, so do so.

++14-bit Bayer formats expanded to 16 bits
++
++
++Description
++===========
++
++These four pixel formats are raw sRGB / Bayer formats with 14 bits per
++colour. Each sample is stored in a 16-bit word, with two unused high
++bits filled with zeros. Each n-pixel row contains n/2 green samples
++and n/2 blue or red samples, with alternating red and blue rows. Bytes
++are stored in memory in little endian order. They are conventionally
++described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an
++example of a small V4L2_PIX_FMT_SBGGR14 image:
++
++**Byte Order.**
++Each cell is one byte, the two most significant bits in the high bytes are
++zero.

+Subject: [PATCH] irqchip/bcm2835: Quiesce IRQs left enabled by
+ bootloader
+
+[ Upstream commit bd59b343a9c902c522f006e6d71080f4893bbf42 ]
+
+Per the spec, the BCM2835's IRQs are all disabled when coming out of
+power-on reset.  Its IRQ driver assumes that's still the case when the
+kernel boots and does not perform any initialization of the registers.
+However the Raspberry Pi Foundation's bootloader leaves the USB
+interrupt enabled when handing over control to the kernel.
+
+Quiesce IRQs and the FIQ if they were left enabled and log a message to
+let users know that they should update the bootloader once a fixed
+version is released.
+
+If the USB interrupt is not quiesced and the USB driver later on claims
+the FIQ (as it does on the Raspberry Pi Foundation's downstream kernel),
+interrupt latency for all other peripherals increases and occasional
+lockups occur.  That's because both the FIQ and the normal USB interrupt
+fire simultaneously:
+
+On a multicore Raspberry Pi, if normal interrupts are routed to CPU 0
+and the FIQ to CPU 1 (hardcoded in the Foundation's kernel), then a USB
+interrupt causes CPU 0 to spin in bcm2836_chained_handle_irq() until the
+FIQ on CPU 1 has cleared it.  Other peripherals' interrupts are starved
+as long.  I've seen CPU 0 blocked for up to 2.9 msec.  eMMC throughput
+on a Compute Module 3 irregularly dips to 23.0 MB/s without this commit
+but remains relatively constant at 23.5 MB/s with this commit.
+
+The lockups occur when CPU 0 receives a USB interrupt while holding a
+lock which CPU 1 is trying to acquire while the FIQ is temporarily
+disabled on CPU 1.  At best users get RCU CPU stall warnings, but most
+of the time the system just freezes.

+Subject: [PATCH] ARM: dts: Make bcm2711 dts more like 5.7
+
+The multiple declarations of pixelvalve2 were causing problems for the
+DT checkers. Aligning the dts files closer to the later kernel versions
+avoids some repetition and should make maintenance easier.

+The Rockchip driver was based on a 4.4 kernel, and had several custom
+Rockchip parts.
+
+Update to 5.4 kernel APIs, with the relevant controls required by
+libcamera, and remove custom Rockchip parts.

+Subject: [PATCH] media: i2c: ov9281: Read chip ID via 2 reads
+
+Vision Components have made an OV9281 module which blocks reading
+back the majority of registers to comply with NDAs, and in doing
+so doesn't allow auto-increment register reading as used when
+reading the chip ID.
+
+Use two reads and manually combine the results.

+
+commit 3347a80965b38f096b1d6f995c00c9c9e53d4b8b upstream.
+
+The RPi 4 uses the hardware handshake lines for CYW43455, but the chip
+doesn't react to HCI requests during DT probe. The reason is the inproper
+handling of the RTS line during startup. According to the startup
+signaling sequence in the CYW43455 datasheet, the hosts RTS line must
+be driven after BT_REG_ON and BT_HOST_WAKE.

+Subject: [PATCH] Bluetooth: hci_bcm: Disallow set_baudrate for
+ BCM4354
+
+commit 5d6f391073d5c1c903ac12be72c66b96b2ae93f4 upstream.
+
+Without updating the patchram, the BCM4354 does not support a higher
+operating speed. The normal bcm_setup follows the correct order
+(init_speed, patchram and then oper_speed) but the serdev driver will
+set the operating speed before calling the hu->setup function. Thus,
+for the BCM4354, don't set the operating speed before patchram.

+Subject: [PATCH] Bluetooth: btbcm: Support pcm configuration
+
+commit 528379902337102b0264fe5343eafb3d6c59fa45 upstream.
+
+Add BCM vendor specific command to configure PCM parameters. The new
+vendor opcode allows us to set the sco routing, the pcm interface rate,
+and a few other pcm specific options (frame sync, sync mode, and clock
+mode). See broadcom-bluetooth.txt in Documentation for more information
+about valid values for those settings.
+
+Here is an example trace where this opcode was used to configure
+a BCM4354:
+
+        < HCI Command: Vendor (0x3f|0x001c) plen 5
+                01 02 00 01 01
+        > HCI Event: Command Complete (0x0e) plen 4
+        Vendor (0x3f|0x001c) ncmd 1
+                Status: Success (0x00)
+
+We can read back the values as well with ocf 0x001d to confirm the
+values that were set:
+        $ hcitool cmd 0x3f 0x001d
+        < HCI Command: ogf 0x3f, ocf 0x001d, plen 0
+        > HCI Event: 0x0e plen 9
+        01 1D FC 00 01 02 00 01 01

+
+The commit 3347a80965b3 ("Bluetooth: hci_bcm: Fix RTS handling during
+startup") is causing at least a regression for AP6256 on Orange Pi 3.
+So do the RTS line handing during startup only on the necessary platform.

+Subject: [PATCH] drm/vc4: add iec958 controls to vc4_hdmi
+
+Although vc4 get an IEC958 formatted stream passed in from userspace
+the driver needs the info from the channel status bits to properly
+set up the hardware, eg for HBR passthrough.
+
+Add iec958 controls so the channel status bits can be passed in
+from userspace.

+ setting
+
+This was a workaround for bugs in hardware on earlier Pi models
+and wasn't totally successful.
+
+It makes audio quality worse on a Pi4 at the higher sample rates

+-- rotation: The device, typically an image sensor, is not mounted upright,
+-  but a number of degrees counter clockwise. Typical values are 0 and 180
+-  (upside down).
++- rotation: The camera rotation is expressed as the angular difference in
++  degrees between two reference systems, one relative to the camera module, and
++  one defined on the external world scene to be captured when projected on the
++  image sensor pixel array.
++
++  A camera sensor has a 2-dimensional reference system 'Rc' defined by
++  its pixel array read-out order. The origin is set to the first pixel
++  being read out, the X-axis points along the column read-out direction
++  towards the last columns, and the Y-axis along the row read-out
++  direction towards the last row.
++
++  A typical example for a sensor with a 2592x1944 pixel array matrix
++  observed from the front is:
++
++              2591       X-axis          0

++                                         V
++
++  The external world scene reference system 'Rs' is a 2-dimensional
++  reference system on the focal plane of the camera module. The origin is
++  placed on the top-left corner of the visible scene, the X-axis points
++  towards the right, and the Y-axis points towards the bottom of the
++  scene. The top, bottom, left and right directions are intentionally not
++  defined and depend on the environment in which the camera is used.
++
++  A typical example of a (very common) picture of a shark swimming from
++  left to right, as seen from the camera, is:
++
++               0               X-axis

++             Y-axis
++
++  with the reference system 'Rs' placed on the camera focal plane:
++

++                              ¸.·˙    !

++
++  When projected on the sensor's pixel array, the image and the associated
++  reference system 'Rs' are typically (but not always) inverted, due to
++  the camera module's lens optical inversion effect.
++
++  Assuming the above represented scene of the swimming shark, the lens
++  inversion projects the scene and its reference system onto the sensor
++  pixel array, seen from the front of the camera sensor, as follows:
++
++            Y-axis
++               ^
++               !
++               !

++               !
++               !

++             0 +------------------------------------->
++               0               X-axis
++
++  Note the shark being upside-down.
++
++  The resulting projected reference system is named 'Rp'.
++
++  The camera rotation property is then defined as the angular difference
++  in the counter-clockwise direction between the camera reference system
++  'Rc' and the projected scene reference system 'Rp'. It is expressed in
++  degrees as a number in the range [0, 360[.
++

++    orientation, while a camera installed on the opposite side of the front one
++    is said to be have ``V4L2_CAMERA_ORIENTATION_BACK`` orientation. Camera
++    sensors not directly attached to the device, or attached in a way that

++
++    The camera is typically mounted upside-down to compensate the lens optical

++
++    If the camera sensor is not mounted upside-down it is required to compensate
++    the lens optical inversion effect and the value of the

+Subject: [PATCH] ARM: dts: Select the actpwr LED trigger on Zeroes
+
+The new "actpwr" LED trigger guarantees that the combined PWR and ACT
+LED is on for at least half of every second. Under heavy SD card
+load it emits a steady 1Hz square wave.

+Subject: [PATCH] vc4: Report channel mapping back to userspace
+
+This follows logic in hdmi-codec.c to use speaker layout
+from ELD to choose a suitable speaker mapping based on
+number of channels requested and signal that in audio
+infoframe  and report this back to userspace.
+
+This allows apps like speaker-test and kodi to get the
+output to the right speakers.

+Subject: [PATCH] ARM: dts: Add UART skip-init properties for U-boot
+
+U-boot can get stuck trying to initialise UARTs that aren't mapped
+to the pin header. There is no reason for U-boot not to rely on the
+initialisation by the firmware, so tag both UARTs with the u-boot
+magic boolean property "skip-init".

+Subject: [PATCH] ARM: proc-v7: Force misalignment of early stmia
+
+In an attempt to prevent the problem of CPUn not starting, explicitly
+misalign the scratch space used to save registers acros the cache
+invalidation.
+
+Notes:
+At this stage in the boot process the core is running with its cache
+disabled. Before enabling the cache its contents must be explicitly
+invalidated, a process that requires quite a few registers that the
+caller must preserve. Evidence suggests that something is writing a
+block of zeroes over that space at a time when all other cores should
+be idle, possibly some kind of write-combiner, and the misalignment is
+designed to disrupt any write-coalescing.
+
+In truth, I don't understand why this patch works, and when the failure
+is so random it is hard to be certain that this isn't just rolling the
+dice again. One interesting test would be to change the "addeq r12, #4"s
+to "addeq r12, #0"s determine see if the offset itself is significant or
+just the additional code.
+

+Subject: [PATCH] overlays: Fix sc16is75x overlays w.r.t. serdev
+
+Enabling serdev support in rpi-5.4.y had the unintended consequence of
+making any UART device node with a subnode look like a "serdev" node,
+which prevents it from having the usual /dev/ttyXXX character device.
+Solve the problem by moving the subnode (a static clock declaration)
+into the root node.
+
+At the same time, regularise (and sometimes correct) the overlays.

+acively setting its direction. This can lead to problems: if the line
+is in input mode by default, we won't be able to drive it later when
+updating the status and also reading its initial value doesn't make
+sense for backlight setting.
+
+Request the line 'as is' initially, so that we can read its value
+without affecting it but then change the direction to output explicitly
+when setting the initial brightness.
+
+Also: check the current direction and only read the value if it's output.

++Name:   maxtherm
++Info:   Configure a MAX6675 or MAX31855 thermocouple as an IIO device.
++
++        For devices on spi1 or spi2, the interfaces should be enabled
++        with one of the spi1-1/2/3cs and/or spi2-1/2/3cs overlays.
++        The overlay expects to disable the relevant spidev node, so also using
++        e.g. cs0_spidev=off is unnecessary.
++
++        Note:   with the 5.7 kernel (and later) there will also be
++                overlays for MAX31855E, MAX31855J, MAX31855K,
++                MAX31885N, MAX31855R, MAX31855S and MAX31855T.
++
++        Example:
++        MAX31855 on /dev/spidev0.0
++            dtoverlay=maxtherm,spi0-0,max31855
++
++Load:   dtoverlay=maxtherm,<param>=<val>

++                                (boolean, required)
++        max6675                 Enable support for the MAX6675 (default)
++        max31855                Enable support for the MAX31855
++        max31855e               Enable support for the MAX31855E

+Subject: [PATCH] dtoverlays: Add the iio_hwmon driver to correct ADC
+ issues
+
+The Linux kernel maintainers removed the hwmon driver for the
+ads1015 used on this board.  They deprecated it in favor of using
+the IIO version of the driver with the iio_hwmon bridge.  This
+patch updates the DRAWS dtoverlay to support that usage.

+Subject: [PATCH] dts: bcm2711: Disable DVP by default
+
+The HDMI DVP should be disabled by default as is the case for other
+display related drivers. This changes resolves an issue when using
+the legacy firmware display driver where the DVP caused the 108 MHz
+clock in HDMI TX to be gated off when Linux started. This effectively
+stopped the firmware from being able to change the HDMI analog PHY
+registers.
+

+The number has to be below the DRM limit of 32 planes total,
+and the current firmware API limit of 16 planes total.
+
+Increase the number to 8 planes per crtc (1 primary,
+6 overlay, and a cursor).

+
+The allocated input and output buffers are initialised in
+buf_init and should only be cleared up in buf_cleanup.
+stop_streaming was (incorrectly) cleaning up the buffers to

+Subject: [PATCH] rtc: rv3028: Write BSM and TCE/TCR to EEPROM
+
+Periodically the RV3028 refreshes registers from the EEPROM. When this
+happens, some settings that have only been committed to registers are
+lost. Change the handling of backup-switchover-mode and
+trickle-resistor-ohms to write the EEPROM instead (if something has
+changed), on the understanding that registers will be refreshed
+afterwards.
+

+Subject: [PATCH] dt/overlays: Add PiFace Digital Device Tree Overlay
+
+The PiFace Digital is a convenient breakout board for the Microchip
+mcp23s17 SPI GPIO port expander.
+
+The first eight GPIOs 0..7 (bank A) are connected to eight output
+terminals and LEDs, plus two relays on the first two outputs. These
+output loads are active-high.
+
+The next eight GPIOs 8..15 (bank B) are connected to eight input
+terminals with four on-board switches connecting them to ground. Inputs
+devices are therefore expected to bridge terminals to ground, so the
+mcp23s17 pullups are activated for GPIO bank B.

++ * PiFace Digital, Device Tree Overlay.
++ * Copyright (C) 2020 Thomas Preston <thomas.preston@codethink.co.uk>
++ *
++ * The PiFace Digital is a convenient breakout board for the Microchip mcp23s17
++ * SPI GPIO port expander.
++ *
++ * The first eight GPIOs 0..7 (bank A) are connected to eight output terminals
++ * and LEDs, plus two relays on the first two outputs. These output loads are
++ * active-high.
++ *
++ * The next eight GPIOs 8..15 (bank B) are connected to eight input terminals
++ * with four on-board switches connecting them to ground. Inputs devices are
++ * therefore expected to bridge terminals to ground, so the mcp23s17 pullups are
++ * activated for GPIO bank B.
++ *
++ * On PiFace Digital, the mcp23s17 is connected to the Raspberry Pi's SPI0 CS0
++ * bus. Each SPI bus supports up to eight addressable child devices. The PiFace
++ * Digital only supports addresses 0-4, which can be configured by jumpers JP1
++ * and JP2.
++ *
++ * You can tell the driver about these jumper configurations with the
++ * spi-present-mask bitmask:
++ *
++ *     | JP1 | JP2 | dtoverlay line in /boot/config.txt         |
++ *     | --- | --- | ------------------------------------------ |
++ *     |  0  |  0  | dtoverlay=pifacedigital                    |
++ *     |  0  |  0  | dtoverlay=pifacedigital:spi-present-mask=1 |
++ *     |  0  |  1  | dtoverlay=pifacedigital:spi-present-mask=2 |
++ *     |  1  |  0  | dtoverlay=pifacedigital:spi-present-mask=4 |
++ *     |  1  |  1  | dtoverlay=pifacedigital:spi-present-mask=8 |
++ *
++ * # Example
++ * Set the dtoverlay config in /boot/config.txt and power off the Raspberry Pi:
++ *
++ *     $ grep pifacedigital /boot/config.txt
++ *     dtoverlay=pifacedigital
++ *     $ sudo systemctl poweroff
++ *
++ * Attach the PiFace Digital and power on the Raspberry Pi.
++ * Then use the libgpiod tools to query the device:
++ *
++ *     $ sudo apt install gpiod
++ *     $ gpiodetect | grep mcp23s17
++ *     gpiochip2 [mcp23s17.0] (16 lines)
++ *
++ * Set GPIO outputs 0, 2 and 5:
++ *
++ *     $ gpioset gpiochip2 0=1 2=1 5=1
++ *
++ * Get GPIO status (input GPIO 8..15 are high, because they are active-low):
++ *
++ *     $ gpioget gpiochip2 {8..15}
++ *     1 1 1 1 1 1 1 1
++ *
++ * And even monitor interrupts:
++ *
++ *     $ gpiomon gpiochip2 {8..15}
++ *     event: FALLING EDGE offset: 11 timestamp: [1597361662.926741667]
++ *     event:  RISING EDGE offset: 11 timestamp: [1597361663.062555051]

+
+The cpus node was originally deleted to match the then downstream
+version of the BCM2835 DTS files, but doing so doesn't seem to make
+any material difference. Its presence is necessary for the CPUFREQ_DT
+support that is planned in the near future, so remove the deletion.

+Subject: [PATCH] ARM: dts: bcm2835: Use the L2 non-allocating alias
+
+The /soc/dma-ranges property on BCM2835 currently results in DMA
+addresses in the range 0x40000000-0x5fffffff. This will allocate in the
+system L2 cache, which may adversely affect performance.
+
+Change the dma-ranges property to give addresses in the range
+0x80000000-0x9fffffff, which are coherent with L2 but non-allocating.

+Subject: [PATCH] media: bcm2835-unicam: Drop WARN on uing direct
+ cache alias
+
+Pi 0&1 pass all ARM accesses through the VPU L2 cache, therefore
+the dma-ranges property sets the cache alias bits to other
+than the direct alias, hence this WARN was firing.
+
+It was overprotective coding, so assume that everything is OK
+with the dma-ranges, and remove the WARN.

+Subject: [PATCH] overlays: Add spi0-1cs and spi0-2cs
+
+The spi0-1cs overlay allows the SPI0 interface to be run with a single
+CS line, which can be useful if GPIOs are in short supply. The no_miso
+parameter is for write-only devices that don't need the return channel,
+and again is there to free up a GPIO.
+
+spi0-2cs is the new name for spi0-cs (now deprecated with a redirect
+to spi0-2cs), but with the addedd no_miso parameter.

+Subject: [PATCH] staging/fbtft: Add support for display variants
+
+Display variants are intended as a replacement for the now-deleted
+fbtft_device drivers. Drivers can register additional compatible
+strings with a custom callback that can make the required changes
+to the fbtft_display structure.
+
+Start the ball rolling by adding adafruit18, adafruit18_green and
+sainsmart18 displays.

+
+The 3B doesn't have the flow control signals connected to the BT modem,
+which limits the maximum usable baud rate to below 1 Mbaud. Use
+921600 as a relatively safe default value, but the krnbt_baudrate
+parameter can still override it.

+Subject: [PATCH] overlays: Update i2c0 overlay to disable the
+ i2c0mux.
+
+The i2c0 overlay was assigning pinctrl settings to node i2c0,
+which is now the port@0 output of the mux. That leaves a high
+chance of it colliding with the port@1 output and not doing
+what was intended.
+
+Set the i2c0 overlay to disable i2c0mux, set the pin-ctrl on
+the root i2c controller, and redirect the alias, so overall it
+behaves exactly as before.
+Combining with dtparam=i2c_vc=on is going to cause conflicts,
+so this is noted in the README.

+Subject: [PATCH] net: bcmgenet: Reset RBUF on first open
+
+If the RBUF logic is not reset when the kernel starts then there
+may be some data left over from any network boot loader. If the
+64-byte packet headers are enabled then this can be fatal.
+
+Extend bcmgenet_dma_disable to do perform the reset, but not when
+called from bcmgenet_resume in order to preserve a wake packet.
+
+N.B. This different handling of resume is just based on a hunch -
+why else wouldn't one reset the RBUF as well as the TBUF? If this
+isn't the case then it's easy to change the patch to make the RBUF
+reset unconditional.
+

+Subject: [PATCH] ASoC: cs42xx8: Only define cs42xx8_of_match once
+
+cs42xx8.c exports cs42xx8_of_match, so there's no need to redefine it
+in cs42xx8-i2c.c - doing so breaks linking when loadable module
+support is disabled. It would be tidy to use the exported match table
+in cs42xx8.c's of_match_table member, but an imported symbol can't be
+used in a module's MODULE_DEVICE_TABLE declaration. Instead, rename
+the duplicated declarations so as not to clash.

+Subject: [PATCH] Update hy28b-overlay.dts
+
+My hy28b TFT stopped working on upgrade to 5.4 kernel.  I had a whitescreen but no obvious errors when using 'sudo vcdbg log msg' or 'dmesg'.  Both /dev/fb0 and /dev/fb1 were present.  Followed this article on waveshare32b that 'reset_gpios needed to be 0 0 1 instead of 0 0 0' (https://forum.armbian.com/topic/13233-any-clues-for-the-creation-of-a-dtoverlay-for-fbtft-on-54y/).  I applied a similar change to this dts file and compiled a new dtbo: 'dtc -O dtb -o hy28b.dtbo hy28b-overlay.dts'.  Fixed my issue - may help others?  I got from the 5.4 upgrade thread that other tft users are having issues with small tfts... https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=269769&p=1706597&hilit=gpio#p1706597

+Subject: [PATCH] overlays: Update display GPIO declarations
+
+The 5.4 kernel changes the way a number of display drivers use GPIOs.
+That change has exposed flaws/broken a number of display overlays, so
+after a trickle of single-display patches this is a best-guess attempt
+to fix the remainder. As none of these changes have been tested on real
+displays there is a possibility that this either doesn't fix the
+problem or even breaks something that was working - apologies if that
+is the case.

+Subject: [PATCH] ARM: bcm2711-rpi.dts: Unlock DMA channels 9 & 10
+
+The downstream-specific override of the 32-bit DMA mask needlessly
+disables channels 9 and 10 - the VPU doesn't use them. This override
+is redundant, so delete it.

+Subject: [PATCH] gpio: Add gpio-fsm driver
+
+The gpio-fsm driver implements simple state machines that allow GPIOs
+to be controlled in response to inputs from other GPIOs - real and
+soft/virtual - and time delays. It can:
++ create dummy GPIOs for drivers that demand them,
++ drive multiple GPIOs from a single input, with optional delays,
++ add a debounce circuit to an input,
++ drive pattern sequences onto LEDs
+etc.

+
+The driver crashed while a NULL pointer returned by i2c_get_adapter()
+has been used to access the i2c bus functions.
+The headphone probing function hb_hp_probe() now returns -EPROBE_DEFER
+in case the i2c module has not been loaded yet.

+
+OV9281 appears to drop the clock to LP mode between frames, but
+the overlay didn't define this at both ends of the CSI2 link.
+The overlay also had an incorrect link frequency defined, not that
+the driver ever checked for one.
+
+Fix both issues.

+Subject: [PATCH] xhci: quirks: add link TRB quirk for VL805
+
+The VL805 controller can't cope with the TR Dequeue Pointer for an endpoint
+being set to a Link TRB. The hardware-maintained endpoint context ends up
+stuck at the address of the Link TRB, leading to erroneous ring expansion
+events whenever the enqueue pointer wraps to the dequeue position.
+
+If the search for the end of the current TD and ring cycle state lands on
+a Link TRB, move to the next segment.

+Subject: [PATCH] firmware: raspberrypi: Add support for tryonce
+ reboot flag
+
+Define a new mailbox (SET_REBOOT_FLAGS) which may be used to
+pass optional flags to the Raspberry Pi firmware that changes
+the behaviour of the bootloader and firmware during a reboot.
+
+Currently this just defines the 'tryboot' flag which causes
+the firmware to load tryboot.txt instead config.txt. This
+alternate configuration file can be used to specify the
+path of an alternate firmware and kernels allowing a fallback
+mechanism to be implemented for OS upgrades.

+Subject: [PATCH] Revert "mailbox: avoid timer start from callback"
+
+This reverts commit 6dc15642c8b830d384fd3e6c9ea63144202b8932.
+
+The Pi 400 shutdown/poweroff mechanism relies on being able to set
+a GPIO on the expander in the pm_power_off handler, something that
+requires two mailbox calls - GET_GPIO_STATE and SET_GPIO_STATE. A
+recent kernel change introduces a reasonable possibility that the
+GET call doesn't completes, and bisecting led to a commit from
+October that changes the timer usage of the mailbox.
+
+My theory is that there is a race condition in the new code that breaks
+the poll timer, but that it normally goes unnoticed because subsequent
+mailbox activity wakes it up again. The power-off mailbox calls happen
+at a time when other subsystems have been shut down, so if one of them
+fails then there is nothing to allow it to recover.
+
+Revert 6dc15642 as (at least) a workaround.
+

+Subject: [PATCH] overlays: Deprecate and delete the sdtweak overlay
+
+The sdtweak overlay has been superseded by the board-specific
+sd_* parameters such as sd_poll_once, sd_overclock etc.
+
+For example, replace:
+
+    dtoverlay=sdtweak,poll_once
+
+with:
+
+    dtparam=sd_poll_once

+Subject: [PATCH] ARM: dts: bcm27xx: Remove enable_headphones setting
+
+The enable_headphones parameter of the snd_bcm2835 module is forced
+to 1 if enable_compat_alsa is 0, so setting them both on the kernel
+command line is pointless (and, in the case of Pi 400 and Pi Zeroes,
+confusing).

+Subject: [PATCH] staging: vcsm-cma: Fix memory leak from not
+ detaching dmabuf
+
+When importing there was a missing call to detach the buffer,
+so each import leaked the sg table entry.
+
+Actually the release process for both locally allocated and
+imported buffers is identical, so fix them to both use the same
+function.

+Subject: [PATCH] media: i2c: imx219: Selection compliance fixes
+
+To comply with the intended usage of the V4L2 selection target when
+used to retrieve a sensor image properties, adjust the rectangles
+returned by the imx219 driver.
+
+The top/left crop coordinates of the TGT_CROP rectangle were set to
+(0, 0) instead of (8, 8) which is the offset from the larger physical
+pixel array rectangle. This was also a mismatch with the default values
+crop rectangle value, so this is corrected. Found with v4l2-compliance.
+
+While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
+CROP_BOUNDS have the same size as the non-active pixels are not readable
+using the selection API. Found with v4l2-compliance.

+Subject: [PATCH] media: bcm2835-unicam: Return early from
+ stop_streaming() if stopped
+
+clk_disable_unprepare() is called unconditionally in stop_streaming().
+This is incorrect in the cases where start_streaming() fails, and
+unprepares all clocks as part of the failure cleanup. To avoid this,
+ensure that clk_disable_unprepare() is only called in stop_streaming()
+if the clocks are in a prepared state.

+ stopping streaming
+
+Commit 65e08c465020d4c5b51afb452efc2246d80fd66f failed to clear the
+clock state when the device stopped streaming. Fix this, as it might
+again cause the same problems when doing an unprepare.

+Subject: [PATCH] media: i2c: imx477: Selection compliance fixes
+
+To comply with the intended usage of the V4L2 selection target when
+used to retrieve a sensor image properties, adjust the rectangles
+returned by the imx477 driver.
+
+The top/left crop coordinates of the TGT_CROP rectangle were set to
+(0, 0) instead of (8, 16) which is the offset from the larger physical
+pixel array rectangle. This was also a mismatch with the default values
+crop rectangle value, so this is corrected. Found with v4l2-compliance.
+
+While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
+CROP_BOUNDS have the same size as the non-active pixels are not readable
+using the selection API. Found with v4l2-compliance.
+
+This commit mirrors 543790f777ba1b3264c168c653db6d415e7c983f done for
+the imx219 sensor.

+Subject: [PATCH] net: lan78xx: Ack pending PHY ints when resetting
+
+lan78xx_link_reset explicitly clears the MAC's view of the PHY's IRQ
+status. In doing so it potentially leaves the PHY with a pending
+interrupt that will never be acknowledged, at which point no further
+interrupts will be generated.
+
+Avoid the problem by acknowledging any pending PHY interrupt after
+clearing the MAC's status bit.

+Subject: [PATCH] overlays: Add missing addresses to ads1015/ads1115
+
+The overlays for the ads1015 and ads1115 I2C ADCs omitted the addresses
+in the main device node names. As well as breaking the conventions for
+I2C devices, this prevents the firmware from renaming them when the
+"reg" property is modified, which in turn stops the overlays from being
+instantiated multiple times.

+Subject: [PATCH] media: i2c: ov5647: Selection compliance fixes
+
+To comply with the intended usage of the V4L2 selection target when
+used to retrieve a sensor image properties, adjust the rectangles
+returned by the ov5647 driver.
+
+The top/left crop coordinates of the TGT_CROP rectangle were set to
+(0, 0) instead of (16, 16) which is the offset from the larger physical
+pixel array rectangle. This was also a mismatch with the default values
+crop rectangle value, so this is corrected. Found with v4l2-compliance.
+
+While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
+CROP_BOUNDS have the same size as the non-active pixels are not readable
+using the selection API. Found with v4l2-compliance.

++Making new Overlays based on existing Overlays
++==============================================
++
++Recent overlays have been designed in a more general way, so that they can be
++adapted to hardware by changing their parameters. When you have additional
++hardware with more than one device of a kind, you end up using the same overlay
++multiple times with other parameters, e.g.
++
++    # 2 CAN FD interfaces on spi but with different pins
++    dtoverlay=mcp251xfd,spi0-0,interrupt=25
++    dtoverlay=mcp251xfd,spi0-1,interrupt=24
++
++    # a realtime clock on i2c
++    dtoverlay=i2c-rtc,pcf85063
++
++While this approach does work, it requires knowledge about the hardware design.
++It is more feasible to simplify things for the end user by providing a single
++overlay as it is done the traditional way.
++
++A new overlay can be generated by using ovmerge utility.
++https://github.com/raspberrypi/utils/blob/master/ovmerge/ovmerge
++
++To generate an overlay for the above configuration we pass the configuration
++to ovmerge and add the -c flag.
++
++    ovmerge -c mcp251xfd-overlay.dts,spi0-0,interrupt=25 \
++               mcp251xfd-overlay.dts,spi0-1,interrupt=24 \
++               i2c-rtc-overlay.dts,pcf85063 \
++    >> merged-overlay.dts
++
++The -c option writes the command above as a comment into the overlay as
++a marker that this overlay is generated and how it was generated.
++After compiling the overlay it can be loaded in a single line.
++
++    dtoverlay=merged
++
++It does the same as the original configuration but without parameters.

+Subject: [PATCH] overlays: seeed-can-fd-hat: clarify how to identify
+ HAT version
+
+It turns out the used CAN SPI chip is not a good way to identify the version of
+the CAN HAT.
+
+There are two different board layouts of the Seeed Studio CAN BUS FD HAT. The
+v1 board doesn't have a battery holder, while the v2 board has. Update the
+overlay README accordinly.

+
+Much effort has been put into finding ways to avoid warnings from dtc
+about overlays, usually to do with the presence of #address-cells and
+size-cells, but not exclusively so. Since the issues being warned about
+are harmless, suppress the warnings to declutter the build output and
+to avoid alarming users.

+otherwise it will be rejected by the pinctrl driver.
