   314   * communicate with the receiver through this shim.
   315   *
   316   * For completeness, the 2 buses differ in the following ways:
   317   *  - DP AUX vs. DDC
   318   *  HDCP registers on the receiver are set via DP AUX for 
DP, and
   319   *  they are set via DDC for HDMI.

   321   *  The offsets of the registers are different for DP vs. 
HDMI
   322   *  - Receiver register masks/offsets

different

   327   *  downstream information is called BINFO, on HDMI it's 
called
   328   *  BSTATUS. To confuse matters further, DP has a BSTATUS 
register
