   13 description:
   14   The ADV7481 and ADV7482 are multi format video decoders with an integrated
   15   HDMI receiver. They can output CSI-2 on two independent outputs TXA and TXB
   16   from three input sources HDMI, analog and TTL.

   29       The ADV748x has up to twelve 256-byte maps that can be accessed via the
   30       main I2C ports. Each map has it own I2C address and acts as a standard
   31       slave device on the I2C bus. The main address is mandatory, others are
   32       optional and remain at default values if not specified.
