Generally I have only one pretty ignorable comment.

The driver uses only THC63_RGB_OUT0 value, or port at 2, and MODE{0,1,2} IC
configuration is ignored.

I don't know if right from the beginning it would be better to support
dual-out modes, preferably both single-in and dual-in ones. Will it
impact port enumeration?

I do understand that the extension is possible, and likely only hardware
accessibility postpones it.
