* from HDCP over DP, so to account for these differences, we need to
|

* communicate with the receiver through this shim.
|
|
*
|
|
* For completeness, the 2 buses differ in the following ways:
|
|
* - DP AUX vs. DDC
|
|
* HDCP registers on the receiver are set via DP AUX for DP, and
|
|
* they are set via DDC for HDMI.
|
|
* - Receiver register offsets
|
|
* The offsets of the registers are different for DP vs. HDMI
|
|
* - Receiver register masks/offsets
|
|
* For instance, the ready bit for the KSV fifo is in a different
|
|
* place on DP vs HDMI
|
|
* - Receiver register names
|
|
* Seriously. In the DP spec, the 16-bit register containing
|
|
* downstream information is called BINFO, on HDMI it's called
|
|
* BSTATUS. To confuse matters further, DP has a BSTATUS register
|
|
* with a completely different definition.
|
|
* - KSV FIFO
|
|
* On HDMI, the ksv fifo is read all at once, whereas on DP it must
|
|
* be read 3 keys at a time
|
|
* - Aksv output
|
|
* Since Aksv is hidden in hardware, there's different procedures
|
|
* to send it over DP AUX vs DDC
