- * - 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
