Header defines the interface for the I915 and MEI_HDCP drivers. This interface is specific to the usage of mei_hdcp from gen9+ platforms for ME FW based HDCP2.2 services.
And Generic HDCP2.2 protocol specific definitions are added at drm/drm_hdcp.h.
v2: Commit msg is enhanced [Daniel] v3: i915_hdcp_comp_master is defined.

I wonder why 'short int' u are assigning it from the encoder 'enum port {} ' Then you down casting it to u8. Maybe is best to export the eum port from intel_drv.h to include/drm/i915_*.h
Thanks Tomas
