Makes sense, ok I will prepare a pure DE33 patch with AFBC and RGB support, removing the YUV code. I think the CSC changes (1-4) are good to stay as it is a change that makes sense regardless and makes the YUV work a bit easier.

Thanks for the other clarifications and vendor code links, will do a bit of reading.
