Hi,

With the new mt8192 scp.img firmware merged on linux-firmware [1] and the
mtk-vcodec decoder support for mt8192 merged in the media tree [2], the DT nodes
for the decoder added in this patch are the last missing piece to have the
decoder usable on mt8192-based machines.

With this patch applied, I was able to run fluster [3] on
mt8192-asurada-spherion and obtain the following results:

VP8: 59/61
VP9: 249/303
H.264: 92/135

So,
