+* 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>;
+ };
+ };
+ };
+};
