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

From: Dmitry Baryshkov
Date: Sat Aug 09 2025 - 05:16:52 EST


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.
