[PATCH v4 06/16] drm/i915/hdcp: HDCP stream encryption support

2020-10-27 Thread Anshuman Gupta
Both HDCP_{1.x,2.x} requires to select/deselect Multistream HDCP bit in TRANS_DDI_FUNC_CTL in order to enable/disable stream HDCP encryption over DP MST Transport Link. HDCP 1.4 stream encryption requires to validate the stream encryption status in HDCP_STATUS_{TRANSCODER,PORT} register driving
