+* STMicroelectronics STM32 lcd-tft display controller
+
+- ltdc: lcd-tft display controller host
+  must be a sub-node of st-display-subsystem
+  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:
+      - "clk-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.
+
+Example:
+
+/ {
+	...
+	soc {
+	...
+		ltdc: display-controller@40016800 {
+			compatible = "st,stm32-ltdc";
+			reg = <0x40016800 0x200>;
+			interrupts = <88>, <89>;
+			resets = <&rcc STM32F4_APB2_RESET(LTDC)>;
+			clocks = <&rcc 1 CLK_LCD>;
+			clock-names = "lcd";
+
+			port {
+				ltdc_out_rgb: endpoint {
+				};
+			};
+		};
+	};
+};
