     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 core in the i.MX
    SoC. This is a Synopsys Designware MIPI CSI-2 host controller core
    combined with a D-PHY core mixed into the same register block. In
    addition this device consists of an i.MX-specific "CSI2IPU gasket"
    glue logic, also controlled from the same register block. The CSI2IPU
    gasket demultiplexes the four virtual channel streams from the host
    controller's 32-bit output image bus onto four 16-bit parallel busses
    to the i.MX IPU CSIs.
    
    Required properties:
    - compatible    : "fsl,imx6-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;
