[PATCH v6 18/35] drm/i915: Implement the HDCP2.2 support for DP

2018-07-13 Thread Ramalingam C
Implements the DP adaptation specific HDCP2.2 functions. These functions perform the DPCD read and write for communicating the HDCP2.2 auth message back and forth. Note: Chris Wilson suggested alternate method for waiting for CP_IRQ, than completions concept. WIP to understand and implement that,
