Thanks Angelo,

I build/boot your branch for the i350-evk board.

I had to revert this commit from your branch:
"15f12798e218 TODO: soc: mediatek: mtk-pm-domains: Support CPU Power 
Domains"
Because it conflict with the "soc: mediatek: MT8365 power support" serie 
[3].

Also, I change back the defconfig to be aligned with the v6.5-rc1

After that, the board boot and drm/display seems working like a charm.
