Re: [PATCH v2 00/42] drm/i915: Implement HDCP2.2
Thank you Tomas for the review on mei related changes. I will work on those changes. Awaiting for the reviews on the I915 and DRM changes before going for v3.

[PATCH v2 00/42] 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 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. Userspace interface remains unchanged as version agnostic.
