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 */ struct intel_hdcp_shim { … };
