Subject[PATCH 4/5] drm/connector: Split out orientation quirk detection
Date
This removes the orientation quirk detection from the code to add
an orientation property to a panel. This is used only for legacy x86
systems, yet we'd like to start using this on devicetree systems where
quirk detection like this is not needed.
