The sequence for HDCP2.2 authentication and encryption is implemented
in I915. Encoder specific implementations are moved into hdcp_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.
DRM_I915 selects INTEL_MEI_HDCP, which selects INTEL_MEI_ME and
INTEL_MEI. If we are interested in disabling the MEI_HDCP and MEI Bus
then we need an option to disable the HDCP2.2 in I915
(like DRM_I915_HDCP2.2!?). Till then they are binded.
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.
Thanks a lot for Daniel Vetter and Sean Paul for reviewing v5.
Major Changes in v6:
- Component master is added in I915_load [Daniel].
- I915 load will wait until all associated components are loaded.
[Daniel]
- Many review comments from Sean Paul and Daniel Vetter are addressed.
- Few patches are merged together. [Sean Paul]
- Gmbus changes for burst read is already merged.
