media: dt-bindings: media: i2c: Add IMX290 CMOS sensor binding

* 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. The CSI-2 bus is the

default. No bindings have been defined for the other busses.

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 in Hz.

- 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.

Required Properties on endpoint:

- data-lanes: check ../video-interfaces.txt

- link-frequencies: check ../video-interfaces.txt

- remote-endpoint: check ../video-interfaces.txt

Example:

	&i2c1 {

		...

		imx290: camera-sensor@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 {

					data-lanes = <1 2 3 4>;

					link-frequencies = /bits/ 64 <445500000>;

					remote-endpoint = <&csiphy0_ep>;

				};

			};

		};
