Subject: [PATCH v3 0/7] hantro: set of small cleanups and fixes
Date: Wed, 25 Mar 2020 18:34:31 -0300 [thread overview]
Message-ID: <20200325213439.16509-1-ezequiel@collabora.com> (raw)
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.
Thanks,
Ezequiel
