[Intel-gfx] [PATCH v5 0/4] Enabling the IGT for HDCP1.4

[Ramalingam C]

Adding a debugfs entry for detecting the valid HDCP sinks to
perform kms_content_protection.

In case of dummy HDMI/DP sinks(EDID whisperers without any parsers)
IGT will skip the HDCP test on that connector instead of failing it.
Hence false alarm are avoided.

For serving above purpose this series has pulled out few changes
from "Implement HDCP2.2" series under review at
https://patchwork.freedesktop.org/series/38254/

"drm/i915: hdcp_check_link only on CP_IRQ" is just a improvement
patch for HDCP1.4. Already received the reviewed-by from Sean Paul.

v5:
  DDC/AUX failures are presented as debug logs instead of errors. [Daniel]

Ramalingam C (4):
  drm/i915: Pullout the bksv read and validation
  drm/i915: hdcp_check_link only on CP_IRQ
  drm/i915/debugfs: hdcp capability of a sink
  drm/i915: Move the DDC/AUX failure msgs to debug log
