IMO, you should move any applicable compatibles to the edp-panel schema. Also, I don't think you should add 'edp-panel' to them. If they can work better with the generic eDP driver, then that should be an internal kernel change without a DT change. Also, if 2 different drivers match on compatible, it's a roll of the dice which driver binds. Rob
