Subject: [PATCH v2 3/7] drm/msm/dp: Add DP and EDP compatibles for SC8280XP

From: Bjorn Andersson <bjorn.andersson@...aro.org>

The SC8280XP platform has four DisplayPort controllers, per MDSS
instance, all with widebus support.

The first two are defined to be DisplayPort only, while the latter pair
(of each instance) can be either DisplayPort or Embedded DisplayPort.
The two sets are tied to the possible compatibels.
