Subject: [PATCH RFC 1/2] dt-bindings: drm/bridge: anx7625: describe Type-C
connector
ANX7625 can be used to mux converted video stream with the USB signals
on a Type-C connector. Describe the optional connector subnode, make it
exclusive with the AUX bus and port@1 as it is impossible to have both
eDP panel and USB-C connector.
