[Intel-gfx] [PATCH 0/6] drm/i915: Fix various issues with noarm register writes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

The CSC unit on SKL/GLK/ICL is borked in various ways. This
can cause black screens and/or premature noarm register latching.
And DC5+PSR can in general also cause premature noarm register
latching. Deal with it all.
