   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.
