* Sony 1/2.5-Inch 8.51Mp CMOS Digital Image Sensor

The Sony imx274 is a 1/2.5-inch CMOS active pixel digital image sensor with

an active array size of 3864H x 2202V. It is programmable through I2C

interface. The I2C address is fixed to 0x1a as per sensor data sheet.

Image data is sent through MIPI CSI-2, which is configured as 4 lanes

at 1440 Mbps.

Required Properties:

- compatible: value should be "sony,imx274" for imx274 sensor

- reg: I2C bus address of the device

Optional Properties:

- reset-gpios: Sensor reset GPIO

The imx274 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:

	sensor@1a {

		compatible = "sony,imx274";

		reg = <0x1a>;

		#address-cells = <1>;

		#size-cells = <0>;

		reset-gpios = <&gpio_sensor 0 0>;

		port {

			sensor_out: endpoint {

				remote-endpoint = <&csiss_in>;

			};

		};

	};
