[GIT PULL] Power management updates for v5.5-rc2

[Rafael J. Wysocki]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.5-rc2

with top-most commit 4c84515da8099f4bab5d9312a0ffaf40f14aa87b

 Merge branches 'pm-cpuidle' and 'acpi-pm'

on top of commit e42617b825f8073569da76dc4510bfa019b1c35a

 Linux 5.5-rc1

to receive power management updates for 5.5-rc2.

These add PM QoS support to devfreq and fix a few issues in that
subsystem, fix two cpuidle issues and do one minor cleanup in there,
and address an ACPI power management problem related to devices with
special power management requirements, like fans.

Specifics:

 - Add PM QoS support, based on the frequency QoS introduced during
   the 5.4 cycle, to devfreq (Leonard Crestez).

 - Fix some assorted devfreq issues (Leonard Crestez).

 - Fix an unintentional cpuidle behavior change (introduced during
   the 5.4 cycle) related to the active polling time limit (Marcelo
   Tosatti).

 - Fix a recently introduced cpuidle helper function and do a minor
   cleanup in the cpuidle core (Rafael Wysocki).

 - Avoid adding devices with special power management requirements,
   like fans, to the generic ACPI PM domain (Rafael Wysocki).

Thanks!
