Subject: [RFC v2 0/4] Implement full clockgating for Kepler1 and 2

Next version of my patchseries for adding clockgating support for
kepler1 and 2 on nouveau. The first version of this series can be found
here:

https://patchwork.freedesktop.org/series/36504/

Some minor changes:
 - Clarified that SLCG stands for 'secondary level clockgating', thanks
   for the small tip nvidia!
 - Removed the concept of levels, this was more useful for debugging
   then anything and having only a single level of clockgating enabled
   does technically open us up to running a configuration nvidia never
   tested. Additionally, this changes NvPmEnableGating into a simple
   boolean option.
 - Fixup nvkm_info() messages so that we don't mention powergating in
   them, since this isn't actually added in this series (and may not be
   for a while, only time will tell :)
 - Don't export unused function gk104_therm_new_()

Lyude Paul (4):
  drm/nouveau: Add support for basic clockgating on Kepler1
  drm/nouveau: Add support for BLCG on Kepler1
  drm/nouveau: Add support for BLCG on Kepler2
  drm/nouveau: Add support for SLCG for Kepler2
