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.
