| "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." |
