+description:
+ 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.

+ description:
+ 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.
