Subject: [PATCH v2 00/14] media: mediatek: vcodec: support video decoder in mt8196

Using vcp micro processor to support video decoder in mt8196 platform,
need to add new firmware interface to communicate with vcp in kernel
side. Then add mt8196 compatible, codec levels/profiles and private data.
Re-write av1 driver to support extend vsi struct, then change irq table
and cdf table size.

This patch set depends on "Add VCP support for mt8196"[1]
