[PATCH v5 1/6] dt-bindings: display/msm: dp-controller: allow eDP for SA8775P

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

On Qualcomm SA8775P the DP controller might be driving either a
DisplayPort or a eDP sink (depending on the PHY that is tied to the
controller). Reflect that in the schema.
