Subject[PATCH v3 0/7] hantro: set of small cleanups and fixes
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

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.


Ezequiel Garcia (7):
v4l2-mem2mem: return CAPTURE buffer first
hantro: Set buffers' zeroth plane payload in .buf_prepare
hantro: Use v4l2_m2m_buf_done_and_job_finish
hantro: Remove unneeded hantro_dec_buf_finish
hantro: Move H264 motion vector calculation to a helper
hantro: Refactor for V4L2 API spec compliancy
