40 "Video port for DPI RGB output.
41 ltdc has one video port with up to 2 endpoints:
42 - for external dpi rgb panel or bridge, using gpios.
43 - for internal dpi input of the MIPI DSI host controller.
44 Note: These 2 endpoints cannot be activated simultaneously.
45 Please refer to the bindings defined in
46 Documentation/devicetree/bindings/media/video-interfaces.txt."
