+* Omnivision OV2680 MIPI CSI-2 sensor
+
+Required Properties:
+- compatible: should be "ovti,ov2680".
+- clocks: reference to the xvclk input clock.
+- clock-names: should be "xvclk".
+
+Optional Properties:
+- powerdown-gpios: reference to the GPIO connected to the powerdown pin,
+ if any. This is an active high signal to the OV2680.
+
+The device node must contain one 'port' child node for its digital output
+video port, and this port must have a single endpoint in accordance with
+ the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Endpoint node required properties for CSI-2 connection are:
+- remote-endpoint: a phandle to the bus receiver's endpoint node.
+- clock-lanes: should be set to <0> (clock lane on hardware lane 0).
+- data-lanes: should be set to <1> (one CSI-2 lane supported).
+
+Example:
+
+&i2c2 {
+ ov2680: camera-sensor@36 {
+ compatible = "ovti,ov2680";
+ reg = <0x36>;
+ clocks = <&osc>;
+ clock-names = "xvclk";
+ powerdown-gpios = <&gpio1 3 GPIO_ACTIVE_HIGH>;
+
+ port {
+ ov2680_mipi_ep: endpoint {
+ remote-endpoint = <&mipi_sensor_ep>;
+ clock-lanes = <0>;
+ data-lanes = <1>;
+ };
+ };
+ };
+};
