The formats added in this patch include: V4L2_PIX_FMT_AYUV32 V4L2_PIX_FMT_XYUV32 V4L2_PIX_FMT_VUYA32 V4L2_PIX_FMT_VUYX32 These formats enable the trasmission of alpha channel data to other drivers and userspace applications in addition to YUV data. For example, buffers generated by drivers in one of these formats can be used by the Weston compositor to display as a texture or flipped directly onto the overlay planes with the help of a DRM driver.

Some old Samsung drivers use the legacy crop API incorrectly: the crop and compose targets are swapped. Normally VIDIOC_G_CROP will return the CROP rectangle of a CAPTURE stream and the COMPOSE rectangle of an OUTPUT stream. The Samsung drivers do the opposite. Note that these drivers predate the selection API. If this 'QUIRK' flag is set, then the v4l2-ioctl core will swap the CROP and COMPOSE targets as well. That way backwards compatibility is ensured and we can convert the Samsung drivers to the selection API.

The latest versions of Google camera and codec HAL depends on such feature. At this stage, it supports only stateless codecs. It has been discussed for a long time (at least over the last 3-4 years), and we finally reached to something that seem to work. This series contain both the API and core changes required to support it and a new m2m decoder driver (cedrus). As the current API is still experimental, the only real driver using it (cedrus) was added at staging[1]. We intend to keep it there for a while, in order to test the API. Only when we're sure that this API works for other cases (like encoders), we'll move this driver out of staging and set the API into a stone. [1] We added support for the vivid virtual driver (used only for testing) to it too, as it makes easier to test the API for the ones that don't have the cedrus hardware" * tag 'media/v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (53 commits) media: dt-bindings: Document the Rockchip VPU bindings media: platform: Add Cedrus VPU decoder driver media: dt-bindings: media: Document bindings for the Cedrus VPU driver media: v4l: Add definition for the Sunxi tiled NV12 format media: v4l: Add definitions for MPEG-2 slice format and metadata media: videobuf2-core: Rework and rename helper for request buffer count media: v4l2-ctrls.c: initialize an error return code with zero media: v4l2-compat-ioctl32.c: add missing documentation for a field media: media-request: update documentation media: media-request: EPERM -> EACCES/EBUSY media: v4l2-ctrls: improve media_request_(un)lock_for_update media: v4l2-ctrls: use media_request_(un)lock_for_access media: media-request: add media_request_(un)lock_for_access media: vb2: set reqbufs/create_bufs capabilities media: videodev2.h: add new capabilities for buffer types media: buffer.rst: only set V4L2_BUF_FLAG_REQUEST_FD for QBUF media: v4l2-ctrls: return -EACCES if request wasn't completed media: media-request: return -EINVAL for invalid request_fds media: vivid: add request support media: vivid: add mc ...

This introduces support for the Sunxi tiled NV12 format, where each component of the YUV frame is divided into macroblocks. Hence, the size of each plane requires specific alignment. The pixels inside each macroblock are coded in linear order (line after line from top to bottom). This tiled NV12 format is used by the video engine on Allwinner platforms: it is the default format for decoded frames (and the only one available in the oldest supported platforms).
