-- ltdc: lcd-tft display controller host
-  Required properties:
-  - compatible: "st,stm32-ltdc"
-  - reg: Physical base address of the IP registers and length of memory mapped region.
-  - clocks: A list of phandle + clock-specifier pairs, one for each
-    entry in 'clock-names'.
-  - clock-names: A list of clock names. For ltdc it should contain:
-      - "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 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.
