drm/amd/display: Add HDCP module
This module manages HDCP for amdgpu driver. The module behaves as a state machine which handles the different authentication states of HDCP The module is divided into 3 major components +--------+ | Hdcp.c | +--------+ Manages the state machine, sends the events to be executed and communicates with the dm +-----------+ |Execution.c| +-----------+ This executes events based on the current state. Also generates execution results as transition inputs +------------+ |Transition.c| +------------+ Decides the next state based on the input and makes requests to hdcp.c to handle. +-------------+ ------> | Execution.c | ------ | +-------------+ | | V +----+ +--------+ +--------------+ | DM | -----> | Hdcp.c | <------------ | Transition.c | +----+ <----- +--------+ +--------------+ v2: Drop unused function definitions Signed-off-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> Signed-off-by: Wenjing Liu <Wenjing.Liu@amd.com> Reviewed-by: Wenjing Liu <Wenjing.Liu@amd.com> Acked-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
