+Freescale i.MX Media Video Device
+=================================
+
+Video Media Controller node
+---------------------------
+
+This is the media controller node for video capture support. It is a
+virtual device that lists the camera serial interface nodes that the
+media device will control.
+
+Required properties:
+- compatible : "fsl,imx-capture-subsystem";
+- ports      : Should contain a list of phandles pointing to camera
+		sensor interface ports of IPU devices
+
+example:
+
+capture-subsystem {
+	compatible = "fsl,imx-capture-subsystem";
+	ports = <&ipu1_csi0>, <&ipu1_csi1>;
+};
+
+
+mipi_csi2 node
+--------------
+
+This is the device node for the MIPI CSI-2 Receiver, required for MIPI
+CSI-2 sensors.
+
+Required properties:
+- compatible	: "fsl,imx6-mipi-csi2", "snps,dw-mipi-csi2";
+- reg           : physical base address and length of the register set;
+- clocks	: the MIPI CSI-2 receiver requires three clocks: hsi_tx
+		  (the D-PHY clock), video_27m (D-PHY PLL reference
+		  clock), and eim_podf;
+- clock-names	: must contain "dphy", "ref", "pix";
+- port@*        : five port nodes must exist, containing endpoints
+		  connecting to the source and sink devices according to
+		  of_graph bindings. The first port is an input port,
+		  connecting with a MIPI CSI-2 source, and ports 1
+		  through 4 are output ports connecting with parallel
+		  bus sink endpoint nodes and correspond to the four
+		  MIPI CSI-2 virtual channel outputs.
+
+Optional properties:
+- interrupts	: must contain two level-triggered interrupts,
+		  in order: 100 and 101;
