No, not to my knowledge. There are no settings for color output
because it is fixed to GBGB/RGRG. I was looking a lot into this driver
(I have few other problems with it, already few other patches posted)
and I could not find a setting for this in datasheet. If you know the
setting for the other color - can you point me to it?
Best regards,
Krzysztof
