+ sensor binding
+
+Commit 8a97a4676f8b1badcd9cfbed2b081342847bb1b1 upstream.
+
+Add devicetree binding for IMX290 CMOS image sensor. Let's also
+add MAINTAINERS entry for the binding and driver.

++* 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>;
++				};
++			};
++		};
