+      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."
