[PATCH 0/9] clk subdev updates
This series addresses various issues inside the reclocking code:
1. after resume the set clocks are reset
2. reclocking not possible while GPU is suspended
3. nouveau always does full reclocks even if only a change of the voltage is
required
Some of the patches were part of the bigger reclocking series I sent months

[RFC PATCH 00/13] Thermal throttling
Adds Nouveau controlled thermal throttling for Kepler+ GPUs. With this I feel
safe enough to add support for Maxwell2 reclocking later on (still hidden
behind a switch, but we can be fairly sure to not overheat hardware if a user
isn't carefull enough)
Contains all patches from my clk update series, but I thought it makes sense
to include those in this series as well for completness.
Please

[PATCH v4 00/37] Volting/Clocking improvements for Fermi and newer
We are slowly getting there!
v4 of the series with some realy good improvements, so I am sure this is like
95% done and only needs some proper polishing and proper Reviews!
I also added the NvVoltOffsetmV module parameter, so that a user is able to
over and !under!-volt the GPU. Overvolting makes sense, when there are still
some reclocking issues left, which might be solved by a higher voltage.

[RFC PATCH 00/29] Current State of my clk patches
Just wanted to post updated versions of my last series/patches. Reviews
welcomed.
It would be also nice if we agree on features I should focus upstreaming, so
that this work can be better splitted or reordered.
Sadly most of my patches depend on the rather big clk subdev rework and I think
those patches shows best, why I think this rework is actually needed and makes
things much easier to add
