+* Sony IMX290 1/2.8-Inch CMOS Image Sensor
+
+The Sony IMX290 is a 1/2.8-Inch CMOS Solid-state image sensor with
+Square Pixel for Color Cameras. It is programmable through I2C and 4-wire
+interfaces. The sensor output is available via CMOS logic parallel SDR output,
+Low voltage LVDS DDR output and CSI-2 serial data output.
+
+Required Properties:
+- compatible: Should be "sony,imx290"
+- reg: I2C bus address of the device
+- clocks: Reference to the xclk clock.
+- clock-names: Should be "xclk".
+- clock-frequency: Frequency of the xclk clock.
+- vdddo-supply: Sensor digital IO regulator.
+- vdda-supply: Sensor analog regulator.
+- vddd-supply: Sensor digital core regulator.
+
+Optional Properties:
+- reset-gpios: Sensor reset GPIO
+
+The imx290 device node should contain one 'port' child node with
+an 'endpoint' subnode. For further reading on port node refer to
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+	&i2c1 {
+		...
+		imx290: imx290@1a {
+			compatible = "sony,imx290";
+			reg = <0x1a>;
+
+			reset-gpios = <&msmgpio 35 GPIO_ACTIVE_LOW>;
+			pinctrl-names = "default";
+			pinctrl-0 = <&camera_rear_default>;
+
+			clocks = <&gcc GCC_CAMSS_MCLK0_CLK>;
+			clock-names = "xclk";
+			clock-frequency = <37125000>;
+
+			vdddo-supply = <&camera_vdddo_1v8>;
+			vdda-supply = <&camera_vdda_2v8>;
+			vddd-supply = <&camera_vddd_1v5>;
+
+			port {
+				imx290_ep: endpoint {
+					clock-lanes = <1>;
+					data-lanes = <0 2 3 4>;
+					remote-endpoint = <&csiphy0_ep>;
+				};
+			};
+		};
