+* Sony 8 Mega-Pixel CMOS Digital Image Sensor
+
+The Sony IMX219 is a diagonal 4.60 mm (Type 1/4.0) CMOS active pixel
+digital image sensor with an active array size of 3280 x 2464.  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 755Mbps/lane
+(with 4 lanes) or 912Mbps/lane (2 lanes.)
+
+
+Required Properties:
+- compatible: shall be "sony,imx219".
+- reg: I2C bus address of the device, shall be <0x10>.
+- clocks: single clock for the sensor INCK signal.
+- xclr-gpios: a single active-low GPIO for the sensor XCLR signal.
+
+Optional Properties:
+- virtual-channel: CSI-2 virtual channel identifier, shall be between 0 and 3,
+    defaults to 0.
+
+The imx219 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 endpoint properties:
+- clock-noncontinuous: the bus always operates in non-continuous mode.
+- data-lanes: shall be <1 2> for 2 lane, or <1 2 3 4> for 4 lane.
+
+Optional endpoint properties:
+- bus-type: shall be 4 - MIPI CSI-2 D-PHY.
+- clock-lanes: shall be zero.
+- lane-polarities: shall be zero (normal polarity) for each lane.
+
+Example:
+
+	camera@10 {
+		compatible = "sony,imx219";
+		reg = <0x10>;
+		xclr-gpios = <&gpio2 10 GPIO_ACTIVE_LOW>;
+		clocks = <&imx219_clk>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		port@0 {
+			reg = <0>;
+
+			imx219_out: endpoint {
+				clock-lanes = <0>;
+				clock-noncontinuous;
+				data-lanes = <1 2>;
+				remote-endpoint = <&mipi_csi_from_mipi_sensor>;
+			};
+		};
+	};
