+* Omnivision OV2685 MIPI CSI-2 sensor
+
+Required Properties:
+- compatible: should be "ovti,ov2685"
+- clocks: reference to the 24M xvclk input clock.
+- clock-names: should be "xvclk".
+- 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:
+ ucam: ov2680@3c {
+ compatible = "ovti,ov2685";
+ reg = <0x3c>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&clk_24m_cam &ucam_rst>;
+
+ clocks = <&cru SCLK_TESTCLKOUT1>;
+ clock-names = "xvclk";
+
+ avdd-supply = <&pp2800_cam>;
+ dovdd-supply = <&pp1800>;
+ reset-gpios = <&gpio2 3 GPIO_ACTIVE_LOW>;
+
+ port {
+ ucam_out: endpoint {
+ remote-endpoint = <&mipi_in_ucam>;
+ data-lanes = <1>;
+ };
+ };
+ };
