+* Omnivision OV02A10 MIPI CSI-2 sensor
+
+Required Properties:
+- compatible: shall be "ovti,ov02a10"
+- clocks: reference to the eclk input clock
+- clock-names: shall be "eclk"
+- dovdd-supply: Digital I/O voltage supply, 1.8 volts
+- avdd-supply: Analog voltage supply, 2.8 volts
+- dvdd-supply: Digital core voltage supply, 1.8 volts
+- powerdown-gpios: reference to the GPIO connected to the powerdown pin,
+ if any. This is an active low signal to the OV02A10.
+- reset-gpios: reference to the GPIO connected to the reset pin, if any.
+ This is an active high signal to the OV02A10.
+
+Optional Properties:
+- rotation: as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt,
+ valid values are 0 (sensor mounted upright) and 180 (sensor
+ mounted upside down).
+
+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.
+
+Example:
+&i2c4 {
+ ov02a10: camera-sensor@3d {
+ 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 = "eclk", "freq_mux";
+ clock-frequency = <24000000>;
+
+ dovdd-supply = <&mt6358_vcamio_reg>;
+ avdd-supply = <&mt6358_vcama1_reg>;
+ dvdd-supply = <&mt6358_vcn18_reg>;
+ powerdown-gpios = <&pio 107 GPIO_ACTIVE_LOW>;
+ reset-gpios = <&pio 109 GPIO_ACTIVE_HIGH>;
+ rotation = <180>;
+
+ port {
+ /* MIPI CSI-2 bus endpoint */
+ ov02a10_core: endpoint {
+ remote-endpoint = <&ov02a10_0>;
+ link-frequencies = /bits/ 64 <390000000>;
+ };
+ };
+ };
+};
