   1 * Analog Devices ADV748X video decoder with HDMI receiver
   2
   3 The ADV7481 and ADV7482 are multi format video decoders with an integrated
   4 HDMI receiver. They can output CSI-2 on two independent outputs TXA and TXB
   5 from three input sources HDMI, analog and TTL.
   6
   7 Required Properties:
   8
   9   - compatible: Must contain one of the following
  10     - "adi,adv7481" for the ADV7481
  11     - "adi,adv7482" for the ADV7482
  12
  13   - reg: I2C slave address
  14
  15 Optional Properties:
  16
  17   - interrupt-names: Should specify the interrupts as "intrq1", "intrq2" and/or
  18                      "intrq3". All interrupts are optional. The "intrq3" interrupt
  19                      is only available on the adv7481
  20   - interrupts: Specify the interrupt lines for the ADV748x
  21
  22 The device node must contain one 'port' child node per device input and output
  23 port, in accordance with the video interface bindings defined in
  24 Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
  25 are numbered as follows.

  29           AIN0          sink            0
  30           AIN1          sink            1
  31           AIN2          sink            2
  32           AIN3          sink            3
  33           AIN4          sink            4
  34           AIN5          sink            5
  35           AIN6          sink            6
  36           AIN7          sink            7
  37           HDMI          sink            8
  38           TTL           sink            9
  39           TXA           source          10
  40           TXB           source          11
  41
  42 The digital output port nodes must contain at least one endpoint.
  43
  44 Ports are optional if they are not connected to anything at the hardware level.
