This series enables the HDCP2.2 for I915. The sequence for HDCP2.2 authentication and encryption is implemented as a generic flow between HDMI and DP. 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. To enable this client driver set the config variable CONFIG_INTEL_MEI_HDCP. 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 strams. Major changes in v9: - Mei_hdcp component binding status will impact I915_load [Daniel]. - worker for sysfs unbind from daniel. - i915-mei_hdcp interface defined at i915_mei_hdcp_interface.h - Same check_work is used for HDCP1.4 and 2.2 link check. [Daniel] - seq_num to and from u32 is done through a helper. [Daniel] - hdcp_wired_protocol() is replaced with a const [Daniel] - Kdocs are added to mei_hdcp.c [Tomas] - i915 port -> mei_ddi_index conversion moved to mei_hdcp [Tomas] - SW tracking of the HDCP spec enabled is used [Daniel] Hopefully covered all suggestions from Tomas and Daniel.
