+Chipone ICN6211 MIPI-DSI to RGB bridge bindings
+
+Required properties:
+- compatible: "chipone,icn6211"
+- reg: I2C slave address
+- clocks: phandle to reference clock for RGB output clock.
+- clock-names: name should be "refclk"
+
+Optional properties:
+- enable-gpios: a GPIO spec for the en pin
+- vdd1-supply: phandle to vdd1 regulator device node
+- vdd2-supply: phandle to vdd2 regulator device node
+- vdd3-supply: phandle to vdd3 regulator device node
+
+Example:
+
+&i2c0 {
+	status = "okay";
+
+	icn6211@2c {
+		compatible = "chipone,icn6211";
+		reg = <0x2c>;
+		clocks = <&osc26m>;
+		clock-names = "refclk";
+		enable-gpios = <&gpio3 RK_PB1 GPIO_ACTIVE_HIGH>;
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			port@0 {
+				reg = <0>;
+
+				icn6211_in_dsi: endpoint {
+					remote-endpoint = <&dsi_out_icn6211>;
+				};
+			};
+
+			port@1 {
+				reg = <1>;
+
+				icn6211_out_panel: endpoint {
+					remote-endpoint = <&panel_in_icn6211>;
+				};
+			};
+		};
+
+	};
+};
