[GIT PULL] Power management updates for 3.7-rc1

[Rafael J. Wysocki]

Hi Linus,

Please pull from the git repository at

  git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm-for-3.7-rc1

to receive power management updates for v3.7-rc1 with top-most commit
b9142167a2bb979b58b98ffcd928a311b55cbd9f

  Merge branch 'pm-qos'

on top of commit 5698bd757d55b1bb87edd1a9744ab09c142abfc2

  Linux 3.6-rc6

Included are:

* Improved system suspend/resume and runtime PM handling for the SH TMU, CMT
  and MTU2 clock event devices (also used by ARM/shmobile).  That required
  some changes to be made to the PM core and suspend/resume callbacks for
  clock event devices to be added.

* Generic PM domains framework extensions related to cpuidle support and
  domain objects lookup using names.

* ARM/shmobile power management updates including improved support for the
  SH7372's A4S power domain containing the CPU core, all ACKed by Magnus Damm.

* cpufreq changes related to AMD CPUs support from Matthew Garrett, Andre
  Przywara and Borislav Petkov.  That has a conflict with your tree resulting
  from the clash between commit e1f0b8e (cpufreq: Remove support for hardware
  P-state chips from powernow-k8) and the Tejun's commit 6889125
  (cpufreq/powernow-k8: workqueue user shouldn't migrate the kworker to another
  CPU) that was merged after these patches had been added to my tree.

* cpu0 cpufreq driver from Shawn Guo.

* cpufreq governor fixes related to the relaxing of limit from Michal Pecio.

* OMAP cpufreq updates from Axel Lin and Richard Zhao.

* cpuidle ladder governor fixes related to the disabling of states from
  Carsten Emde and me.

* cpuidle cleanups from Daniel Lezcano.

* Runtime PM core updates related to the interactions with the system suspend
  core from Alan Stern and Kevin Hilman.

* Wakeup sources modification allowing more helper functions to be called from
  interrupt context from John Stultz and additional diagnostic code from Todd
  Poynor.

* System suspend error code path fix from Feng Hong.

Thanks!
