[PATCH 0/2] allow partly reclocking on chipset
some chipset have working engine reclocking, but broken memory reclocking like
Fermi. We should for now, add the functionality to allow partly reclocking for
those.
Allthough this doesn't give as much performance as one might wish, it is till
noticeable and may improve performance enough to be noted.

[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

I guess those should be int, similar to the changes you made in patch 1.

[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
ago, some things have changed though.
This is also preparation work of
