     * Analog Devices ADV748X video decoder with HDMI receiver
     
     The ADV7481 and ADV7482 are multi format video decoders with an integrated
     HDMI receiver. They can output CSI-2 on two independent outputs TXA and TXB
     from three input sources HDMI, analog and TTL.
     
     Required Properties:
     
       - compatible: Must contain one of the following
        - "adi,adv7481" for the ADV7481
        - "adi,adv7482" for the ADV7482
    
      - reg: I2C slave addresses
        The ADV748x has up to twelve 256-byte maps that can be accessed via the
        main I2C ports. Each map has it own I2C address and acts as a standard
        slave device on the I2C bus. The main address is mandatory, others are
        optional and remain at default values if not specified.
    
    Optional Properties:
    
      - interrupt-names: Should specify the interrupts as "intrq1", "intrq2" and/or
                         "intrq3". All interrupts are optional. The "intrq3" interrupt
                         is only available on the adv7481
      - interrupts: Specify the interrupt lines for the ADV748x
      - reg-names : Names of maps with programmable addresses.
                    It shall contain all maps needing a non-default address.
                    Possible map names are:
                      "main", "dpll", "cp", "hdmi", "edid", "repeater",
                      "infoframe", "cbus", "cec", "sdp", "txa", "txb"
    
    The device node must contain one 'port' child node per device input and output
    port, in accordance with the video interface bindings defined in
    Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
    are numbered as follows.
    
              Name          Type            Port
            ---------------------------------------
              AIN0          sink            0
              AIN1          sink            1
              AIN2          sink            2
              AIN3          sink            3
              AIN4          sink            4
              AIN5          sink            5
              AIN6          sink            6
              AIN7          sink            7
              HDMI          sink            8
              TTL           sink            9
              TXA           source          10
              TXB           source          11
    
    The digital output port nodes, when present, shall contain at least one
    endpoint. Each of those endpoints shall contain the data-lanes property as
    described in video-interfaces.txt.
    
    Required source endpoint properties:
      - data-lanes: an array of physical data lane indexes
        The accepted value(s) for this property depends on which of the two
        sources are described. For TXA 1, 2 or 4 data lanes can be described
        while for TXB only 1 data lane is valid. See video-interfaces.txt
        for detailed description.
    
    Ports are optional if they are not connected to anything at the hardware level.
    
    Example:
