I must admit that I just copied this list from Oleksandrs original patch. The MEDIA type it identifies(MEDIA_BUS_FMT_RGB666_1X24_CPADHI) looks special. I will drop lvds666 while applying, unless I get other feedback. (Note: travelling, earliest in the weekend) Btw. anyway I can add data-mapping to panel-common - and then list the allowed enum values in each binding? I would love to have a central definition of data-mapping, and then let the users only allow the relevant subset so we catch errors in DT files early.
