-* 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>;
