+* 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>;
+               vddd-supply = <&camera_vddd_1v12>;
+               vdda-supply = <&pm8994_l17>;
+               lens-focus = <&ad5820>;
+               enable-gpios = <&msmgpio 25 GPIO_ACTIVE_HIGH>;
+               clocks = <&mmcc CAMSS_MCLK0_CLK>;
+               clock-frequency = <24000000>;
+               port {
+                       imx214_ep: endpoint {
+                               data-lanes = <1 2 3 4>;
+                               link-frequencies = /bits/ 64 <480000000>;
+                               remote-endpoint = <&csiphy0_ep>;
+                       };
+               };
+       };
