+* Sony IMX296 1/2.8-Inch CMOS Image Sensor
+
+The Sony IMX296 is a 1/2.9-Inch active pixel type CMOS Solid-state image
+sensor with square pixel array and 1.58 M effective pixels. This chip features
+a global shutter with variable charge-integration time. It is programmable
+through I2C and 4-wire interfaces. The sensor output is available via CSI-2
+serial data output (1 Lane).
+
+Required Properties:
+- compatible: Should be "sony,imx296"
+- reg: I2C bus address of the device
+- clocks: Reference to the mclk clock.
+- clock-names: Should be "mclk".
+- clock-frequency: Frequency of the mclk clock in Hz.
+- vddo-supply: Interface power supply.
+- vdda-supply: Analog power supply.
+- vddd-supply: Digital power supply.
+
+Optional Properties:
+- reset-gpios: Sensor reset GPIO
+
+The imx296 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.
+
+Required Properties on endpoint:
+- data-lanes: check ../video-interfaces.txt
+- remote-endpoint: check ../video-interfaces.txt
+
+Example:
+	&i2c1 {
+		...
+		imx296: camera-sensor@1a {
+			compatible = "sony,imx296";
+			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 = "mclk";
+			clock-frequency = <37125000>;
+
+			vddo-supply = <&camera_vddo_1v8>;
+			vdda-supply = <&camera_vdda_3v3>;
+			vddd-supply = <&camera_vddd_1v2>;
+
+			port {
+				imx296_ep: endpoint {
+					data-lanes = <1>;
+					remote-endpoint = <&csiphy0_ep>;
+				};
+			};
+		};
