Please check my Verisilicon DC8200 driver, which is already part of
drm-misc-next now.
The display controller here seems to be a earlier one from
Verisilicon.it looks like a DC8000, or maybe a more earlier one?
The DCU is a Vivante DCUltra IP rather than a DC8000 series.
It's an earlier generation display controller and was customized for
Nuvoton, so it doesn't have a public model ID.
Because of that lineage, parts of the register layout and functionality
remain similar to older DC IPs.
Please refer to MA35D1 datasheet for more details.
