The ADV7511, ADV7511W and ADV7513 are HDMI audio and video
transmitters compatible with HDMI 1.4 and DVI 1.0. They support color
space conversion, S/PDIF, CEC and HDCP. The transmitter input is
parallel RGB or YUV data.

I2C slave addresses.
The ADV7511/11W/13 internal registers are split into four pages
exposed through different I2C addresses, creating four register
maps. 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 revert to defaults if not specified.
