| * - 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 |
