I've manged to boot it using Collabora for-kernel-ci next kernel, which is based
on media-state/master 6.5.0-rc1. I suspect there is more depedencies then
described which might be pending in other trees. As all the patches are from
other trees submission, I suppose this is fine for now. Notice that the boot log
does not look very promising though, I will do some more testing, but from clean
boot, after udev have filled the HW database:
[ 10.399826] mt7921e 0000:01:00.0: WM Firmware Version: ____010000, Build Time: 20230117170942
[ 11.882202] mtk-vcodec-dec 18000000.video-codec: [MTK_V4L2][ERROR] Not supported ctrl id: 0xa40903
[ 11.882202]
[ 11.910945] mtk-vcodec-dec 18000000.video-codec: [MTK_V4L2][ERROR] Not supported ctrl id: 0xa40903
This is produced when udev calls /usr/lib/udev/v4l_id, I don't think its doing
anything that would explain error logs.
