[PATCH v7 00/14] media: mediatek: vcodec: support video decoder in mt8196

[Kyrie Wu <kyrie.wu@mediatek.com>]

This patch set adds support for the video decoder on the MediaTek MT8196
platform, leveraging the VCP microprocessor for enhanced performance. It
introduces new firmware interfaces for kernel-side communication with VCP,
adds MT8196 compatible, codec levels/profiles, and private data. Rewrites
the AV1 driver to support extended VSI structures, then change irq table
and cdf table size.

This patch set depends on "Add MediaTek VCP remoteproc driver support"[1]

Compliance Test Result:
- v4l2-compliance: 48/49 tests passed, 1 failed (known issue)
- fail: v4l2-test-controls.cpp(981): ret (got 13)
-        test VIDIOC_G/S/TRY_EXT_CTRLS: FAIL

Fluster Test Result:
- H264:
- Ran 95/135 tests successfully   in 73.540 secs
- H265:
- Ran 142/147 tests successfully  in 100.168 secs
- VP9:
- Ran 276/305 tests successfully  in 106.804 secs
- AV1:
- Ran 240/242 tests successfully  in 23.991 secs

Changed in v7:
- Rebased on top of the latest media tree
- Update the MT8196 decoder binding to require VCP, reject SCP, and validate
  the four fixed hardware clock names on each decoder child node.

Changed in v6:
- Rebase to latest codebase
- Change patch authors and Signed-off-by trailers to Kyrie Wu
- Use safer firmware selection flow for decoder and encoder initialization
- Add VCP IPI id validation and keep invalid messages from stopping the
  message processing thread
- Fix VCP ACK state handling, stale ACK handling, and interruptible ACK wait
  retry handling
- Stop the VCP message thread, unregister callbacks, and release the VCP
  remoteproc reference during cleanup
- Replace VCP readiness busy-wait polling with sleepable polling
- Add VCP encoder capability callback
- Fix MT2110R debug output string
- Update the MT8196 decoder binding commit message according to review
- Keep MT8196 compatible definition before patches that use it
- Fill AV1 reference C plane buffer size

Changed in v5:
- Rebase to latest codebase
- Move vcp init method to driver pdata structures
- change decoder dt-bindings patch's commit message
- MT8189 base on MT8196 patch set

Changed in v4:
- Rebase to latest codebase
- Move dt-bindings and compatible to the after of vcp driver ready
- MT8189 base on MT8196 patch set

Changed in v3:
- Depends on change no update
- Add Compliance and Fluster test result
- Re-write the commit message for patch 12
- Change the patches according to review suggestion for patch: 3/4/5/6/14

Changed in v2:
- re-write the commit message for patch 1
