Hi Thomas, Tomi,

Just curious, does this patch imply that code like this needs to be
written for every single LCD type and resolution that can be connected
to omap2? Maybe there is a better way, like a common table of timings
and values that can be selected with a module option or even
autodetected.

Thanks,
jaya
