+LG LG4573 TFT liquid crystal display with SPI control bus
+
+Required properties:
+  - compatible: "lg4573"
+  - reg: address of the panel on SPI bus
+  - display-timings: timings for the connected panel according to [1]
+
+The panel must obey rules for SPI slave device specified in document [2].
+
+Optional properties:
+  - power-on-delay: delay after turning regulators on [ms]
+
+[1]: Documentation/devicetree/bindings/video/display-timing.txt
+[2]: Documentation/devicetree/bindings/spi/spi-bus.txt
+
+Example:
+
+	lcd_panel: display@0 {
+		#address-cells = <1>;
+		#size-cells = <1>;
+		compatible = "lg,lg4573";
+		spi-max-frequency = <10000000>;
+		reset-gpios = <&gpio2 11 0>;
+		reg = <0>;
+		power-on-delay = <10>;
+		display-timings {
+			480x800p57 {

+				clock-frequency = <27000027>;
+				hactive = <480>;
+				vactive = <800>;
