I'm not talking about drivers. I'm talking about bindings. Those are not necessarily 1-1. There's no reason the simple panel driver can't have an 'edp-connector' entry. Also, since you have EDID, you should be using that for timing data IMO, and the binding needs to have enough information to support that. It may if DP-aux comes from the bridge chip or it may not if you need to describe that connection. Again, this is independent from what Linux chooses to do. If Linux chooses to have its own timing information that's its choice. Another OS may choose to use EDID. Rob
