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