-* Sony 1/3.06-Inch 13.13Mp CMOS Digital Image Sensor
-
-The Sony imx214 is a 1/3.06-inch CMOS active pixel digital image sensor with
-an active array size of 4224H x 3200V. It is programmable through an I2C
-interface.
-Image data is sent through MIPI CSI-2, through 2 or 4 lanes at a maximum
-throughput of 1.2Gbps/lane.
-
-
-Required Properties:
-- compatible: Shall be "sony,imx214".
-- reg: I2C bus address of the device. Depending on how the sensor is wired,
-       it shall be <0x10> or <0x1a>;
-- enable-gpios: GPIO descriptor for the enable pin.
-- vdddo-supply: Chip digital IO regulator (1.8V).
-- vdda-supply: Chip analog regulator (2.7V).
-- vddd-supply: Chip digital core regulator (1.12V).
-- clocks: Reference to the xclk clock.
-- clock-frequency: Frequency of the xclk clock.
-
-Optional Properties:
-- flash-leds: See ../video-interfaces.txt
-- lens-focus: See ../video-interfaces.txt
-
-The imx214 device node shall 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:
-
-	camera-sensor@1a {
-		compatible = "sony,imx214";
-		reg = <0x1a>;
-		vdddo-supply = <&pm8994_lvs1>;
