[Intel-gfx] [PATCH v14 16/33] drm/i915: Fix KBL HDCP2.2 encrypt status signalling

2019-02-16 Thread Ramalingam C
HDCP transmitter is supposed to indicate the HDCP encryption status of the link through enc_en signals in a window of time called "window of opportunity" defined by HDCP HDMI spec. But on KBL this timing of signalling has an issue. To fix the issue this WA of resetting the signalling is required.
