[Intel-gfx] [PATCH 0/3] drm/i915: MST link training locking and cleanups

[ville.syrjala at linux.intel.com]

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

While glancing at the MST hpd code I noticed we have no locking in there
to protect the link retraining against a concurrent modeset. So I added some,
and then ocd struct and had to clean up the code a bit.

These patches are available at 
git://github.com/vsyrjala/linux.git mst_fixes_cleanups

In the repo I've also included an earlier patch which attempts to enable
the DDI PLL for MST on SKL [1]
