fixing GDDR5 reclocking on kepler cards
this is my first patch on the list through git send-mail and I hope everything
is set up right, sorry for the noise here, but I don't want to try with an
empty mail :)
as the subject already says, this patch fixes one of the more serious issues
while reclocking gddr5 on kepler cards. It works for me and for a bunch of others
I met on IRC.

NVA3 clock tree improvements
Following a series of patches to improve nouveaus clock tree parsing. Reclocking these engines (all but memory) is pretty stable on the cards I've tested. Please review and merge when approved.
These patches do not solve the problem that core/shader engine doesn't like to be clocked up too far without fb following, with visible corruption as a result. I suspect this problem is unrelated

[PATCH] drm/nouveau/nv50: Reclock when memory was stolen
Here's a quick-but-I-guess-tidy-fix for faulty behaviour someone reported in NVAF. I'm just not sure if the check for nvaa/nvac should still be in nv50_pm_clocks_pre... I believe this is wrong as they can reclock perfectly well (except the non-existing memory). Anyone has a definite answer to that?
