[Intel-gfx] [PATCH v2 00/17] drm/i915: Port A HPD and other HPD cleanups

[ville.syrjala at linux.intel.com]

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

Second posting of the HPD port A series, with some new added goodies
at the end ;)

I tried to accomodate Paulo's review comments on v1 of the series [1]
and noticed a few other warts myself that I tried to sort out. Additonally
I added a bunch of BXT cleanups to the end, and an extra regression
fix for gen2-4.

I've not had time to test this version yet. I'll try to do that soon,
and especially give it a shakedown on a BXT.

The entire series is available at
git://github.com/vsyrjala/linux.git port_a_hotplug_7
