I'm testing this series with my local MT8188 setup + an external 4K
display, and I feel there is something missing in it.
With these patches the external display can be lit up on my end, but I
only see glitches and no meaningful content is rendered.
Could you check again and send the updated series with the fix?

Thanks,
Fei
