+
+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.

-Subject: [PATCH 317/773] 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.

+
+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.

+Subject: [PATCH 332/782] bcm2835-dma: Add support for per-channel flags
+
+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.

-
-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.

+
+We accidentally call mutex_unlock(&pcm512x->mutex); twice in a row.
+
+I re-wrote the error handling to use "goto unlock;" instead of returning

-Subject: [PATCH 336/773] ASoC: pcm512x: Fix a double unlock in
- 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.

+ 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.

-Subject: [PATCH 341/773] 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.

-
-There were a number of logging lines that were using
-inappropriate formatting under 64bit kernels.
-
-The kernel_id field passed to/from the VPU was being
-abused for storing the struct vc_sm_buffer *.
-This breaks with 64bit kernels, so change to using an IDR.

+Subject: [PATCH 354/782] 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 355/782] 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.

- 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 357/773] 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 366/782] 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.

-Subject: [PATCH 367/773] 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.

- vc_sm_ioctl_alloc_share
- vc_sm_ioctl_import_dmabuf

-Are declared without a prototype. They are not used outside of this

+Subject: [PATCH 380/782] 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

+
+Also give the sc16is750-i2c overlay the xtal parameter for symmetry.

+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.

+
+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

+The default resolution code was different for each role

-Subject: [PATCH 392/773] 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.

+Subject: [PATCH 393/782] rtc: rv3028: add new driver
+
+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.

-+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.
-+
-+

+
+Break the clock setting logic out from the main hw_params. It's

+commit c95e3a4b96293403a427b5185e60fad28af51fdd upstream.
+
+Different processing blocks are required for different sampling
+rates and power parameters. Set the processing blocks based
+on this information.

+Subject: [PATCH 399/782] ASoC: tlv320aic32x4: Model PLL in CCF
+
+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

-Date: Thu, 21 Mar 2019 17:58:46 -0700
-Subject: [PATCH 401/773] 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.

+
+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.

-Subject: [PATCH 402/773] ASoC: tlv320aic32x4: Model DAC/ADC dividers in CCF
-
-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.

+
+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 403/773] 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.

-
-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 405/782] 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 406/773] 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.

+
+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.

+ 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.

+
+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.

- 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.

-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.

+
+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

+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

+
+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...)

+
+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.

+
+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 438/782] 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()

+
+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.

-
-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.

-
-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 445/773] staging: bcm2835-audio: Use PCM runtime values
- 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.

+The chip->audio_mutex is used basically for protecting the opened

+
+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 452/782] 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.

-
-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 453/773] 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.
-

+From: Takashi Iwai <tiwai@suse.de>
+Date: Tue, 4 Sep 2018 17:58:49 +0200
+Subject: [PATCH 453/782] 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.

-Subject: [PATCH 454/773] 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.

+Subject: [PATCH 458/782] 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.

+ 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.

-Subject: [PATCH 463/773] staging: bcm2835-audio: Simplify card object
- 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.

+
+commit d048385a070552ae819f99f05bd03ec41072783d upstream.
+
+When it comes to declaring variables it's preferred, when possible, to
+use an inverted tree organization scheme.
+
+Also, removes some comments that were useless.

+
+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

+parameter instead, but use the maximum as default.

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

-Subject: [PATCH 489/773] 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.

+Subject: [PATCH 492/782] 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.

+
+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.

-Subject: [PATCH 502/773] 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.

+Subject: [PATCH 503/782] 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.

-Subject: [PATCH 504/773] 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.

+Subject: [PATCH 507/782] 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.

-Subject: [PATCH 508/773] 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.

-Subject: [PATCH 510/773] overlays: Fix mmc-related overlays after refactor
-
-The addition of the mmcnr node to the base dtbs caused some overlays to
-not work as they should. Patch up pi3-disable-wifi, balena-fin and
-sdhost.

+V4L2 uses nsecs, whilst MMAL uses usecs, but the code wasn't converting

+Subject: [PATCH 517/782] 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.

+
+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.

- and I2C
-
-The assigned register ranges for UART, SPI and I2C were too wasteful.
-In order to avoid overlapping with the new functions on BCM2838
-reduce the ranges.

-Subject: [PATCH 522/773] ARM: bcm283x: Extend the WDT DT node out to cover the
- 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.

-Subject: [PATCH 527/773] 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 527/782] 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 528/773] 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 528/782] 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 529/782] 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 529/773] 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 530/773] 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).
++
++Example Node:
++

-+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).
-+
-+Example Node:
-+
-+pcie0: pcie@f0460000 {
-+ reg = <0x0 0xf0460000 0x0 0x9310>;
-+ interrupts = <0x0 0x0 0x4>;
-+ compatible = "brcm,bcm7445-pcie";

-+ interrupt-map-mask = <0 0 0 7>;
-+ interrupt-map = <0 0 0 1 &intc 0 47 3

-+ 0 0 0 3 &intc 0 49 3
-+ 0 0 0 4 &intc 0 50 3>;
-+ clocks = <&sw_pcie0>;
-+ clock-names = "sw_pcie";
-+ msi-parent = <&pcie0>; /* use PCIe's internal MSI controller */

-Subject: [PATCH 550/773] 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 552/773] drivers: char: add chardev for mmap'ing Argon control
- registers
-
-Based on the gpiomem driver, allow mapping of the decoder register
-spaces such that userspace can access control/status registers.
-This driver is intended for use with a custom ffmpeg backend accelerator
-prior to a v4l2 driver being written.

+Date: Wed, 12 Dec 2018 15:51:48 -0800
+Subject: [PATCH 554/782] 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 555/773] 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.

+
+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.

-Subject: [PATCH 558/773] 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.

-Subject: [PATCH 561/773] 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.

+Subject: [PATCH 563/782] 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 564/773] 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 576/782] 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 576/773] 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 577/773] 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.

+We have another thing called the "done fence" that tracks when the

+Subject: [PATCH 585/782] 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 586/782] 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 586/773] 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 587/773] 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.

+Date: Wed, 27 Mar 2019 17:45:01 +0000
+Subject: [PATCH 592/782] 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.

-From: Dave Stevenson <dave.stevenson@raspberrypi.org>
-Date: Tue, 26 Mar 2019 14:43:06 +0000
-Subject: [PATCH 592/773] gpu: vc4-fkms: Switch to the newer mailbox frame
- buffer API.
-
-The old mailbox FB API was ideally deprecated but still used by
-the FKMS driver.
-Update to the newer API.
-
-NB This needs current firmware that accepts ARM allocated buffers
-through the newer API.

-Subject: [PATCH 593/773] 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.

+There is a slightly nasty hack in that all crtcs share the

-work well enough, but ought to be fixed at a later date.

+Subject: [PATCH 609/782] 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.

-From 0e26e8b14d72d122ed1a3f66a53829944980fd4e Mon Sep 17 00:00:00 2001
-From: Eric Anholt <eric@anholt.net>
-Date: Tue, 16 Apr 2019 15:58:54 -0700
-Subject: [PATCH 610/773] 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 610/782] drm/v3d: Clock V3D down when not in use.
+
+My various attempts at re-enabling runtime PM have failed, so just
+crank the clock down when V3D is idle to reduce power consumption.

+ function static
+
+Removes obsolete comment about wanting to pass a function
+pointer into mmal-vchiq as we now do.
+As the function is passed as a function pointer, the function itself
+can be static.

+ *
+- * 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).

- * 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 625/782] 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 626/773] 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 630/773] 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 635/782] 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.

-Subject: [PATCH 636/773] 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.

+From d13c2f390560d6329ee2d2bffe0405587fc4f58f Mon Sep 17 00:00:00 2001
+From: Phil Elwell <phil@raspberrypi.org>

+Subject: [PATCH 638/782] 2711: Add basic 64-bit support
+
+This commit adds initial support for 64-bit 2711 builds. However,
+it will only work as much as it does if the Pi4 RAM is limited to
+1GB - more than that and several things break (SD card, coherent
+allocations, etc.)

-Subject: [PATCH 639/773] 2711: Add basic 64-bit support
-
-This commit adds initial support for 64-bit 2711 builds. However,
-it will only work as much as it does if the Pi4 RAM is limited to
-1GB - more than that and several things break (SD card, coherent
-allocations, etc.)

+Subject: [PATCH 642/782] arm: dts: Change downstream vchiq compatible string
+
+The new cache line size mechanism requires a different vchiq compatible
+string on BCM2836 and BCM2837, but the downstream dts files didn't
+inherit the upstream changes.

-Subject: [PATCH 643/773] arm: dts: Change downstream vchiq compatible string
-
-The new cache line size mechanism requires a different vchiq compatible
-string on BCM2836 and BCM2837, but the downstream dts files didn't
-inherit the upstream changes.

+Subject: [PATCH 643/782] 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 644/773] 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 653/782] 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 664/773] 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.

+
+commit 0e3743d870711ae4daf1e7170c8d9381564e244d upstream.
+
+The ds2805 has a structure named: w1_family_2d, which surely
+comes from a w1_ds2431 module. This commit fixes this name to
+prevent confusion and mark a correct family name.

-
-commit 0e3743d870711ae4daf1e7170c8d9381564e244d upstream.
-
-The ds2805 has a structure named: w1_family_2d, which surely
-comes from a w1_ds2431 module. This commit fixes this name to
-prevent confusion and mark a correct family name.

+
+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.

-This commit is fixing a smatch warning:
-drivers/w1/slaves/w1_ds2413.c:61 state_read() warn: impossible condition '(*buf == 255) => ((-128)-127 == 255)'
-by creating additional u8 variable for the bus reading and comparision
-
-Reported-by: kbuild test robot <lkp@intel.com>
-Reported-by: Dan Carpenter <dan.carpenter@oracle.com>
-Cc: Dan Carpenter <dan.carpenter@oracle.com>

+Subject: [PATCH 682/782] 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 685/773] staging: vcsm-cma: Rework to use dma APIs, not CMA
-
-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.

+
+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 692/782] 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.

-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 695/782] i2c: bcm2835: Move IRQ request after clock code in
+ 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.

-Subject: [PATCH 695/773] 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 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

-
-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

-Actually try to go get the clock and test for its existence
-before trying to set up a downstream clock based upon it.

+Subject: [PATCH 698/782] 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.

+
+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.

- 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.

-Subject: [PATCH 704/773] configs: arm64/bcm2711: Use CONFIG_BRCMSTB_THERMAL
- instead of CONFIG_BCM2835_THERMAL
-
-The Raspberry Pi 4 uses the brcmstb thermal driver rather than brcm2835,
-based on the device tree compatible string 'brcm,avs-tmon-bcm2838'. With
-CONFIG_BRCMSTB_THERMAL enabled, reading temperature from
-/sys/class/thermal/thermal_zone0/temp works as expected instead of
-returning EINVAL.

+Subject: [PATCH 705/782] 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.

-Subject: [PATCH 706/773] 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.

-Subject: [PATCH 713/773] overlays: audremap: Support GPIOs 18 & 19
-
-PWM audio can also be used on GPIOs 18 and 19, so add the pins_18_19
-parameter to select that location. pins_12_13 explicitly chooses GPIOs
-12 and 13, although this is the default behaviour so is there only for
-completeness.

+ 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 717/782] drm/vc4: Attach margin props 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 717/773] 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 718/773] drm/vc4: Attach margin props 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 720/773] drm/vc4: Ensure zpos is always initialised
-
-The compiler is warning that default_zpos can be used
-uninitialised as there is no default case to catch all plane
-types.
-No other plane types should ever be presented to vc4_fkms_plane_init,
-but add a default case regardless.

+ nodes
+
+The GIC has a virtual interface maintenance interrupt and the PMU
+interrupts need affinity mappings as they are wired to generic SPIs.
+
+Also, delete incorrect PMU compatible string.

-
-The GIC has a virtual interface maintenance interrupt and the PMU
-interrupts need affinity mappings as they are wired to generic SPIs.
-
-Also, delete incorrect PMU compatible string.

-Subject: [PATCH 728/773] Fixup FKMS interrupt handing for non-existent display
-
-If an errant interrupt flag was received from a non-existent display,
-a NULL pointer access was made. Protect against this by checking if a
-second display is present prior to checking the interrupt flags.

+ 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 731/782] 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 731/773] hid: usb: Add device quirks for Freeway Airmouse T3
- 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.
-
-See: https://github.com/raspberrypi/firmware/issues/1189

-Subject: [PATCH 732/773] 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 733/782] 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.

+Subject: [PATCH 734/782] drm/modes: Support modes names 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).

+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 22045e8e52bd802f743f0471242782fc3b479707 upstream.
+
+The TV margins has been defined as a structure inside the
+drm_connector_state structure so far. However, we will need it in other
+structures as well, so let's move that structure definition so that it can
+be reused.

-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.

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

- properties
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-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.

+Subject: [PATCH 743/782] 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 744/782] 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.

-Subject: [PATCH 744/773] 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 745/773] 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.

-For generic ALSA, all you need is the bcm2835.h change, but
-have also added structures for IEC958 HDMI. Not sure how to
-test those.

+Subject: [PATCH 748/782] net: bcmgenet: Workaround for Pi 4B network issue
+
+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.
+
+Forcing renegotiation has been found to be an effective workaround, so
+add an automatic renegotiation after the link comes up for the first
+time; enable it with genet.force_reneg=y - by default it is disabled.

+
+The details over when and how a driver is to service the

+
+Copy the event handling as used by the vc4-kms driver slightly

-Subject: [PATCH 749/773] net: bcmgenet: Workaround for Pi 4B network issue
-
-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.
-
-Forcing renegotiation has been found to be an effective workaround, so
-add an automatic renegotiation after the link comes up for the first
-time; enable it with genet.force_reneg=y - by default it is disabled.
-
-See: https://github.com/raspberrypi/linux/issues/3108

-
-Copy the event handling as used by the vc4-kms driver slightly

+Subject: [PATCH 755/782] 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.

+
+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 759/773] drm/vc4: Use drm_atomic_helper_check_plane_state() to
- 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 762/773] drm/vc4: Fix NULL pointer dereference in the async
- update path
-
-vc4_plane_atomic_async_update() calls vc4_plane_atomic_check()
-which in turn calls vc4_plane_setup_clipping_and_scaling(), and since
-commit 58a6a36fe8e0 ("drm/vc4: Use
-drm_atomic_helper_check_plane_state() to simplify the logic"), this
-function accesses plane_state->state which will be NULL when called
-from the async update path because we're passing the current plane
-state, and plane_state->state has been assigned to NULL in
-drm_atomic_helper_swap_state().
-
-Pass the new state instead of the current one (the new state has
-->state set to a non-NULL value).

+Subject: [PATCH 765/782] 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 766/782] 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

-Subject: [PATCH 766/773] 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 767/773] 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)
