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

29      The ADV7511/11W/13 internal registers are split into four pages
30      exposed through different I2C addresses, creating four register
31      maps. Each map has it own I2C address and acts as a standard slave
32      device on the I2C bus. The main address is mandatory, others are
33      optional and revert to defaults if not specified.
