Merge tag 'media/v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull new experimental media request API from Mauro Carvalho Chehab: "A new media request API This API is needed to support device drivers that can dynamically change their parameters for each new frame. 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 ...
