So basically we say that this panel is bpc=8 but connected so we only utilise 6 bits per color - seems like a waste but may be good enough. There are other panels that is connected in the same way.

No, this is a 6 bpc panel, I just forgot to fix that :-S

Applied.

Should I send a fix on top of drm-misc, or would you like to do so ?

Please send a fix.
