The description of how messages are processed by the core was not always very clear. Reword it to improve this. In particular for the USER_CONTROL_* messages a critical bit was missing in that the core also checks for the CEC_LOG_ADDRS_FL_ALLOW_RC_PASSTHRU flag. This was confusing.

The SMPTE-2084 transfer functions maps to the luminance range of 0-10000 cd/m^2. Other transfer functions use the traditional range of 0-100 cd/m^2. I didn't take this into account so the luminance was off by a factor of 100. Since qv4l2 made the same mistake in reverse I never noticed this until I tested with actual SMPTE-2084 video.

The on-chip SRAM of i.MX6S is only 128 KiB. 4 KiB of that are allocated for suspend to RAM since commit df595746 ("ARM: imx: add suspend in ocram support for i.mx6q"). Reduce the requested IRAM size to 124 KiB to avoid an allocation failure that causes the coda driver to not use the SRAM at all.

coda_command_sync calls coda_command_async, which writes the bit_stream_param context variable into the BIT_STREAM_PARAM register, overwriting the previously set value during coda_start_decoding. Instead of writing to the register, set bit_stream_param to ensure that the decoder sequence init command is executed with the escape flag set.

While looking at a compiler warning, I noticed the use of IS_ERR_OR_NULL, which is generally a sign of a bad API design and should be avoided. In this driver, this is fairly easy, we can simply stop storing error pointers in persistent structures, and change the two functions that might return either a NULL pointer or an error code to consistently return error pointers when failing. of_parse_subdev() now separates the error code and the pointer it looks up, to clarify the interface. There are two cases where this function originally returns 'NULL', and I have changed that to '0' for success to keep the current behavior, though returning an error would also make sense there.

Passing uninitialized flags into device_prep_interleaved_dma is clearly a bad idea, and we get a compiler warning for it: drivers/media/platform/omap/omap_vout_vrfb.c: In function 'omap_vout_prepare_vrfb': drivers/media/platform/omap/omap_vout_vrfb.c:273:5: error: 'flags' may be used uninitialized in this function [-Werror=maybe-uninitialized] It seems that the OMAP dmaengine ignores the flags, but we should pick the right ones anyway.

Commit a53e35db ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior.

After the DocBook conversion a number of pixfmt description files just had a number in the filename (pix-fmt-004, 006, etc) which was not very descriptive. Rename them. Note that pixfmt-008.rst was folded into colorspaces-details.rst, so that file is deleted. It's easier to maintain that way. Also moved the colorspace sections to the end of the chapter. The old order was weird: the "Standard Image Formats" section (an intro into pixel formats) was followed by the colorspace sections instead of the pixel format descriptions. Moving it to the end resolved that issue. Signed-off-by: Hans Verkuil <hansverk@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
