341 | * - DP AUX vs. DDC | |
342 | * HDCP registers on the receiver are set via DP AUX for DP, and | |
343 | * they are set via DDC for HDMI. | |
344 | * - Receiver register offsets | |
345 | * The offsets of the registers are different for DP vs. HDMI | |
346 | * - Receiver register masks/offsets | |
347 | * For instance, the ready bit for the KSV fifo is in a different | |
348 | * place on DP vs HDMI | |
349 | * - Receiver register names | |
350 | * Seriously. In the DP spec, the 16-bit register containing | |
351 | * downstream information is called BINFO, on HDMI it's called | |
352 | * BSTATUS. To confuse matters further, DP has a BSTATUS register | |
353 | * with a completely different definition. | |
354 | * - KSV FIFO | |
355 | * On HDMI, the ksv fifo is read all at once, whereas on DP it must | |
356 | * be read 3 keys at a time | |
357 | * - Aksv output | |
