Merge tag 'pm-5.0-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki: "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)" * tag 'pm-5.0-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM-runtime: Fix autosuspend_delay on 32bits arch PM-runtime: Fix 'jiffies' in comments after switch to hrtimers cpufreq: scmi: Fix frequency invariance in slow path doc: trace: fix reference to cpuidle documentation file cpufreq: check if policy is inactive early in __cpufreq_get() cpufreq: scpi/scmi: Fix freeing of dynamic OPPs cpuidle / Documentation: Update cpuidle MAINTAINERS entry cpufreq / Documentation: Update cpufreq MAINTAINERS entry PM: sleep: call devfreq suspend/resume
