[Nouveau] [RFC PATCH 00/13] Thermal throttling

[Karol Herbst]

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 comment

Karol Herbst (13):
  clk: Rename nvkm_pstate_calc to nvkm_clk_update and export it
  clk: Remove dstate
  clk: Make pstate a pointer to nvkm_pstate
  clk: Hold information about the current cstate status
  clk: We should pass the pstate id around not the index in the list
  clk: Set clocks to pre suspend state after suspend
  clk: Check pm_runtime status before reclocking
  therm: Don't cancel the timer
  therm: Move the temp readout into the alarm
  therm: Trigger reclock in temperature daemon
  bios: add thermal policies table
  clk: parse thermal policies for throttling thresholds
  clk: thermal throttling
