It took me some time to figure out the meaning of this sentence... Did
you want to say that backward compatibility is fully preserved?
You are removing samsung,dynamic-range and samsung,ycbcr-coeff. I would
assume that now:
1. on all these board these values would be parsed from EDID/MODE/DPCD
message?
2. everything would work as previously?
Am I understanding it correctly?
The patch itself looks good.
Best regards,
Krzysztof
