All new users of the eDP panels are supposed to use the generic "edp-panel" compatible device on the AUX bus.

a=openpgp; fpr=8F88381DD5C873E4AE487DA5199BF1243632046A The panel-edp driver supports legacy compatible strings for several eDP panels which were never used in DT files present in Linux tree and most likely have never been used with the upstream kernel. Drop compatibles for these panels in favour of using a generic "edp-panel" device on the AUX bus.
