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]
