Subject: Re: [PATCH 0/3] media: mediatek: vcodec: Add driver to support 10bit

Hi,

phew things missing in this cover letter,

Please at least provide the score before and after these changes. Full report is
also nice. You didn't explain why H.264 is not tested.

This cover letter is missing v4l2-compliance report. This is needed whenever
format mechanism is modified in a driver (not just for new drivers). Please add
and make sure there is not regression too.

Its seems like 6.5.0-rc1 with the depedency and this patchset does not boot on
MT8195 Chromebooks. Which paltform has this been validated on ?
