ME FW contributes a vital role in HDCP2.2 authentication. HDCP2.2 driver needs to communicate to ME FW for each step of the HDCP2.2 authentication. ME FW prepare and HDCP2.2 authentication parameters and encrypt them as per spec. With such parameter Driver prepares HDCP2.2 auth messages and communicate with HDCP2.2 sink. Similarly HDCP2.2 sink's response is shared with ME FW for decrypt and verification. Once All the steps of HDCP2.2 authentications are complete on driver's request ME FW will configure the port as authenticated and supply the HDCP keys to the Gen HW for encryption. Only after this stage HDCP2.2 driver can start the HDCP2.2 encryption for a port. ME FW is interfaced to kernel through MEI Bus Driver. To obtain the HDCP2.2 services from the ME FW through MEI Bus driver MEI Client Driver is developed. v2: hdcp files are moved to drivers/misc/mei/hdcp/ [Tomas] v3: Squashed the Kbuild support [Tomas] UUID renamed and Module License is modified [Tomas] drv_data is set to null at remove [Tomas] v4: Module name is changed to "MEI HDCP" I915 Selects the MEI_HDCP v5: Remove redundant text from the License header Fix malformed licence Removed the drv_data resetting. v6: K-Doc addition.
