ltdc can have up to 2 endpoints:
- dpi external gpios: for rgb panels or external bridge ICs.
- dpi internal ios: connected internally to dsi.
Note: Refer to the reference manual to know if the dsi is
present on your device.

- "lcd" for the clock feeding the output pixel clock & IP clock.
- resets: reset to be used by the device (defined by use of RCC macro).
Required nodes:
- - Video port for RGB output.
+ - 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.
