The screen itself doesn't seem to want to work as a generic "edp-panel", as it appears the EDID isn't readable until after the whole lot is enabled - I'm guessing this might be to do with the Analogix driver's force-hpd behaviour - but since we do already have the legacy data, it doesn't seem unreasonable to keep using it. Thanks, Robin.
