+* Omnivision OV02A10 MIPI CSI-2 sensor
+
+Required Properties:
+- compatible: shall be "ovti,ov02a10"
+- clocks: reference to the xvclk input clock
+- clock-names: shall be "xvclk"
+- avdd-supply: Analog voltage supply, 2.8 volts
+- dovdd-supply: Digital I/O voltage supply, 1.8 volts
+- dvdd-supply: Digital core voltage supply, 1.8 volts
+- reset-gpios: Low active reset gpio
+
+The device node shall contain one 'port' child node with an
+'endpoint' subnode for its digital output video port,
+in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+The endpoint optional property 'data-lanes' shall be "<1>".
+
+Example:
+&i2c4 {
+	sensor_sub: sensor_sub {
+		compatible = "ovti,ov02a10";
+		reg = <0x3d>;
+		pinctrl-names = "default";
+		pinctrl-0 = <&camera_pins_cam1_mclk_on>;
+
+		clocks = <&topckgen CLK_TOP_MUX_CAMTG2>,
+			<&topckgen CLK_TOP_UNIVP_192M_D8>;
+		clock-names = "xvclk", "freq_mux";
+
+		avdd-supply = <&mt6358_vcama1_reg>;
+		dvdd-supply = <&mt6358_vcn18_reg>;
+		dovdd-supply = <&mt6358_vcamio_reg>;
+		pwdn-gpios = <&pio 107 1>;
+		reset-gpios = <&pio 109 1>;
+
+		port@0 {
+		   ov02a10_core: endpoint {
+		       remote-endpoint = <&ov02a10_0>;
+			   data-lanes = <1>;
+		   };
+		};
+	};
+};
