   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 addresses
  14     The ADV748x has up to twelve 256-byte maps that can be accessed via the
  15     main I2C ports. Each map has it own I2C address and acts as a standard
  16     slave device on the I2C bus. The main address is mandatory, others are
  17     optional and remain at default values if not specified.
  18
  19 Optional Properties:
  20
  21   - interrupt-names: Should specify the interrupts as "intrq1", "intrq2" and/or
  22                      "intrq3". All interrupts are optional. The "intrq3" interrupt
  23                      is only available on the adv7481
  24   - interrupts: Specify the interrupt lines for the ADV748x
  25   - reg-names : Names of maps with programmable addresses.
  26                 It shall contain all maps needing a non-default address.
  27                 Possible map names are:
  28                   "main", "dpll", "cp", "hdmi", "edid", "repeater",
  29                   "infoframe", "cbus", "cec", "sdp", "txa", "txb"
  30
  31 The device node must contain one 'port' child node per device input and output
  32 port, in accordance with the video interface bindings defined in
  33 Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
  34 are numbered as follows.
  35
  36           Name          Type            Port
  37         ---------------------------------------
  38           AIN0          sink            0
  39           AIN1          sink            1
  40           AIN2          sink            2
  41           AIN3          sink            3
  42           AIN4          sink            4
  43           AIN5          sink            5
  44           AIN6          sink            6
  45           AIN7          sink            7
  46           HDMI          sink            8
  47           TTL           sink            9
  48           TXA           source          10
  49           TXB           source          11
  50
  51 The digital output port nodes must contain at least one endpoint.
  52
  53 Ports are optional if they are not connected to anything at the hardware level.
