Hmm, not quite following you here. As far as the controller goes
it supports the formats I mentioned:
- 8/10/12/16 bits RGB 4:4:4
- 8/10/12/16 bits YCbCr 4:4:4
- 8/10/12 bits YCbCr 4:2:2
- 8/10/12/16 bits YCbCr 4:2:0

As for the CSC it supports RGB 4:4:4 to/from YCbCr 4:4:4 or 4:2:2
in every defined color depth.

So, everything except 4:2:0 (I had to check documentation, I
though that CSC supported less formats).

Of course this is all limited by the implementation that HW team
decides to choose.

Best regards,
Jose Miguel Abreu
