[Intel-gfx] [PATCH v6] drm/i915/dp: Validate cached link rate and lane count before retraining

2017-04-06 Thread Manasi Navare
Currently intel_dp_check_link_status() tries to retrain the link if Clock recovery or Channel EQ for any of the lanes indicated by intel_dp->lane_count is not set. However these values cached in intel_dp structure can be stale if link training has failed for these values during previous modeset.
