+* Omnivision OV5695 MIPI CSI-2 sensor
+
+Required Properties:
+- compatible: should be "ovti,ov5695"
+- clocks: reference to the 24M xvclk input clock.
+- clock-names: should be "xvclk".
+- dovdd-supply: Digital I/O voltage supply, 1.8 volts
+- avdd-supply: Analog voltage supply, 2.8 volts
+- dvdd-supply: Digital core voltage supply, 1.2 volts
+- reset-gpios: Low active reset gpio
+
+The device node must contain one 'port' child node for its digital output
+video port, in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+&i2c1 {
+	compatible = "ovti,ov5695";
+	reg = <0x36>;
+	pinctrl-names = "default";
+	pinctrl-0 = <&clk_24m_cam &wcam_rst>;
+
+	clocks = <&cru SCLK_TESTCLKOUT1>;
+	clock-names = "xvclk";
+
+	avdd-supply = <&pp2800_cam>;
+	dvdd-supply = <&pp1250_cam>;
+	dovdd-supply = <&pp1800>;
+
+	reset-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>;
+
+	port {
+		wcam_out: endpoint {
+			remote-endpoint = <&mipi_in_wcam>;
+			data-lanes = <1 2>;
+		};
+	};
+};
