Subject: [GIT PULL] More power management updates for v5.5-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.5-rc1-2

with top-most commit 1e4230f56dac141eb149ebec01f41b6fad27e503

 Merge branches 'pm-sleep', 'pm-cpuidle', 'pm-cpufreq', 'pm-devfreq'
and 'pm-avs'

on top of commit 6e9f879684b46331f51d0c76ebee981c788417db

 Merge tag 'acpi-5.5-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive additional power management updates for 5.5-rc1.

These fix an ACPI EC driver bug exposed by the recent rework
of the suspend-to-idle code flow, reintroduce frequency
constraints into device PM QoS (in preparation for adding
QoS support to devfreq), drop a redundant field from struct
cpuidle_state and clean up Kconfig in some places.

Specifics:

 - Avoid a race condition in the ACPI EC driver that may cause
   systems to be unable to leave suspend-to-idle (Rafael Wysocki).

 - Drop the "disabled" field, which is redundant, from struct
   cpuidle_state (Rafael Wysocki).

 - Reintroduce device PM QoS frequency constraints (temporarily
   introduced and than dropped during the 5.4 cycle) in preparation
   for adding QoS support to devfreq (Leonard Crestez).

 - Clean up indentation (in multiple places) and the cpuidle drivers
   help text in Kconfig (Krzysztof Kozlowski, Randy Dunlap).

Thanks!
