312 * from HDCP over DP, so to account for these differences, we need to
313 * communicate with the receiver through this shim.

317 * HDCP registers on the receiver are set via DP AUX for DP, and

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