+* Omnivision 1/7.5-Inch B&W VGA CMOS Digital Image Sensor
+
+The Omnivision OV7251 is a 1/7.5-Inch CMOS active pixel digital image sensor
+with an active array size of 640H x 480V. It is programmable through a serial
+I2C interface.
+
+Required Properties:
+- compatible: Value should be "ovti,ov7251".
+- clocks: Reference to the xclk clock.
+- clock-names: Should be "xclk".
+- clock-frequency: Frequency of the xclk clock.
+- enable-gpios: Chip enable GPIO. Polarity is GPIO_ACTIVE_HIGH. This corresponds
+ to the hardware pin XSHUTDOWN which is physically active low.
+- vdddo-supply: Chip digital IO regulator.
+- vdda-supply: Chip analog regulator.
+- vddd-supply: Chip digital core regulator.
+
+The device node shall contain one 'port' child node with a single '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:
+
+ &i2c1 {
+ ...
+
+ ov7251: camera-sensor@60 {
+ compatible = "ovti,ov7251";
+ reg = <0x60>;
+
+ enable-gpios = <&gpio1 6 GPIO_ACTIVE_HIGH>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&camera_bw_default>;
+
+ clocks = <&clks 200>;
+ clock-names = "xclk";
+ clock-frequency = <24000000>;
+
+ vdddo-supply = <&camera_dovdd_1v8>;
+ vdda-supply = <&camera_avdd_2v8>;
+ vddd-supply = <&camera_dvdd_1v2>;
+
+ port {
+ ov7251_ep: endpoint {
+ clock-lanes = <1>;
+ data-lanes = <0>;
+ remote-endpoint = <&csi0_ep>;
+ };
+ };
+ };
+ };
