Subject: [GIT PULL] Power management updates for v5.0-rc2

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.0-rc2

with top-most commit 343e60e52a3a093bb7baeca441789724fcac4bb5

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

on top of commit bfeffd155283772bbe78c6a05dec7c0128ee500c

 Linux 5.0-rc1

to receive power management updates for 5.0-rc2.

These fix fallout after starting to use hrtimers in the runtime PM
framework, fix a few cpufreq issues, fix a recently broken reference
to cpuidle documentation, update MAINTAINERS entries for cpufreq and
cpuidle and make the recently added system suspend and resume support
in devfreq actually work.

Specifics:

 - Prevent integer overflows from occurring on 32-bit when
   converting milliseconds to nanoseconds in the runtime PM
   framework and update comments that still refer to jiffies
   in it (Vincent Guittot, Ladislav Michl).

 - Fix the SCMI cpufreq driver to always use the same frequency
   units for arch_set_freq_scale() and make the scale-invariant
   load tracking acutally work with this driver (Quentin Perret).

 - Fix freeing of dynamic OPPs in the SCPI and SCMI cpufreq drivers
   broken during the 4.20 defelopment cycle (Viresh Kumar).

 - Prevent the cpufreq core from attempting to return the current
   frequency of offline CPUs (Sudeep Holla).

 - Add devfreq suspend and resume hooks (missed previously) to the
   PM core to make the recently added system suspend and resume
   support in devfreq actually work (Lukasz Luba).

 - Update MAINTAINERS entries for cpufreq and cpuidle, mostly to add
   references to new/current documentation to them (Rafael Wysocki).

 - Fix a recently broken reference to cpuidle documentation (Otto
   Sabart).

Thanks!
