Hi all, Cleanups and fixes, third iteration. The main idea here is to address two issues, and while at it, clean the driver a bit. The first issue can be found in Patch 1, when the Request API is used, the CAPTURE buffer should be returned _before_ the OUTPUT buffer, to avoid waking up userspace prematurely. I noticed this issue while working on the rkvdec driver, but this time I've decided to tackle it at the core, in v4l2_m2m_buf_done_and_job_finish(). The second issue is a simple compliance issue, which is solved by refactoring the driver, dealing with internal set format properly. Note that patch 7 still needs reviews from device tree maintainers. Changes v3: * Rebased media master. * Revert buffer sequence removal change. Changes v2: * Fix compile warning introduced by patch 6. * I'm adding two additional patches this time. Patch 7 converts the binding to json-schema, and patch 8 puts linux-rockchip mailing list in MAINTAINERS.
