This should be on the encoder, not the connector.
I've seen it is bound to connector in rgb and to encoder in hdmi.
Is it correct rgb mode_valid under connector funcs?
Otherwise I send a patch also for that one.
This would need to be fixed as well. Bridges attach to encoder, not
connectors, so if you ever have a bridge connected to the RGB output
(like on the A13-Olinuxino), mode_valid isn't called at the moment.
Ok, I will do the same for rgb and submit a patchset,
need some time to test both lvds and rgb.
