[PATCH 00/43] drm/i915: Implement HDCP2.2

Based on HDCP1.4 framework introduced by Sean Paul, this series
implements the HDCP2.2 in I915.

The sequence for HDCP2.2 authentication and encryption is implemented
in I915. Encoder specific implementations are moved into hdcp2_shim.

Intel HWs supports HDCP2.2 through ME FW. Hence this series
introduces a client driver for mei bus, so that for HDCP2.2
authentication, HDCP2.2 stack in I915 can avail the services from
ME FW.

Userspace interface remains unchanged as version agnostic. When
userspace request for HDCP enable, Kernel will detect the HDCP source
and sink's HDCP version(1.4/2.2)capability and enable the best capable
version for that combination.

This series enables the HDCP2.2 for Type0 content streams.

Yes its bit lengthy series. Please tolerate. Thanks

Known TO-DOs:
- Improving the commit messages.
- Improving the documentation.
- Not so happy about i/f between I915 and MEI_HDCP drivers :(
