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 VCP support for mt8196"[1]
