This series adds support for mt8192 h264/vp8/vp9 decoder drivers. Firstly, refactor
power/clock/interrupt interfaces for mt8192 is lat and core architecture.
Secondly, add new functions to get frame buffer size and resolution according
to decoder capability from scp side. Then add callback function to get/put
capture buffer in order to enable lat and core decoder in parallel.
Then add to support MT21C compressed mode and fix v4l2-compliance fail.
Next, extract H264 request api driver to let mt8183 and mt8192 use the same
code, and adds mt8192 frame based h264 driver for stateless decoder.
Lastly, add vp8 and vp9 stateless decoder drivers.
Patches 1 to refactor power/clock/interrupt interface.
Patches 2~4 get frame buffer size and resolution according to decoder capability.
Patches 5~6 enable lat and core decode in parallel.
Patch 7~10 add to support MT21C compressed mode and fix v4l2-compliance fail.
patch 11 record capture queue format type.
Patch 12~13 extract h264 driver and add mt8192 frame based driver for h264 decoder.
Patch 14~15 add vp8 and vp9 stateless decoder drivers.
----
Dependents on "Support multi hardware decode using of_platform_populate"[1].
This patches are the second part used to add mt8192 h264 decoder. And the base part is [1].

firmware instead, using chip name is not reasonable to separate

Perhaps you wanted to append the referred v4l2-compliance output (fixed) ?
As we started doing with other codec driver submission (just did last month for
NXP), can you state which software this driver was tested with ? I have started
receiving feedback from third party that MTK driver support is not reproducible,
I would like to work with you to fix the situation.

Nicolas
