Subject: drm/panel-edp: Move FriendlyELEC HD702E
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5c323ea948ff0f9e50418119cbbb3d94f2bd6a96;p=thirdparty%2Fkernel%2Flinux.git

drm/panel-edp: Move FriendlyELEC HD702E

FriendlyELEC's HD702E module is an eDP panel (in as much as it's some
LVDS LCD behind a Chrontel CH7511B eDP bridge), so move its data over
to the eDP driver, also resolving the warning about the missing bpc
value in the process.

The unfortunate combination of HPD not being wired up and the RK3399 eDP
controller's behaviour seems to result in the EDID not being readable
over DP-AUX without probing the panel first, thus the hard-coded mode is
still needed to get things going.
