+Bindings for Ingenic JZ4780 LCD Controller
+
+LCD Controller is the Display Controller for the Ingenic JZ4780 SoC
+
+Required properties:
+- compatible: should be "ingenic,jz4780-lcd"
+- reg: Should contain the address & size of the LCD controller registers.
+- interrupts: Should specify the interrupt provided by parent.
+- clocks: Should contain two clock specifiers for the JZ4780_CLK_TVE JZ4780_CLK_LCD0PIXCLK.
+- clock-names : Must be "lcd_clk", "lcd_pixclk";
+- port: A port node with endpoint definitions as defined in
+  Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Optional properties:
+- interrupt-parent: phandle to parent interrupt controller
+
+Example:
+
+lcd: jz4780-lcdk at 0x13050000 {
+	compatible = "ingenic,jz4780-lcd";
+	reg = <0x13050000 0x1800>;
+
+	clocks = <&cgu JZ4780_CLK_TVE>, <&cgu JZ4780_CLK_LCD0PIXCLK>;
+	clock-names = "lcd_clk", "lcd_pixclk";
+
+	interrupt-parent = <&intc>;
+	interrupts = <31>;
+
+	jz4780_lcd_out: port {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			jz4780_out_hdmi: endpoint at 0 {
+				reg = <0>;
+				remote-endpoint = <&hdmi_in_lcd>;
+			};
+		};
+
+};
