Pull more power management updates from Rafael Wysocki: "These revert a recent PM core change that introduced a regression, fix the build when the recently added Kryo cpufreq driver is selected, add support for devices attached to multiple power domains to the generic power domains (genpd) framework, add support for iowait boosting on systens with hardware-managed P-states (HWP) enabled to the intel_pstate driver, modify the behavior of the wakeup_count device attribute in sysfs, fix a few issues and clean up some ugliness, mostly in cpufreq (core and drivers) and in the cpupower utility. Specifics: - Revert a recent PM core change that attempted to fix an issue related to device links, but introduced a regression (Rafael Wysocki) - Fix build when the recently added cpufreq driver for Kryo processors is selected by making it possible to build that driver as a module (Arnd Bergmann) - Fix the long idle detection mechanism in the out-of-band (ondemand and conservative) cpufreq governors (Chen Yu) - Add support for devices in multiple power domains to the generic power domains (genpd) framework (Ulf Hansson) - Add support for iowait boosting on systems with hardware-managed P-states (HWP) enabled to the intel_pstate driver and make it use that feature on systems with Skylake Xeon processors as it is reported to improve performance significantly on those systems (Srinivas Pandruvada) - Fix and update the acpi_cpufreq, ti-cpufreq and imx6q cpufreq drivers (Colin Ian King, Suman Anna, Sébastien Szymanski) - Change the behavior of the wakeup_count device attribute in sysfs to expose the number of events when the device might have aborted system suspend in progress (Ravi Chandra Sadineni) - Fix two minor issues in the cpupower utility (Abhishek Goel, Colin Ian King)" * tag 'pm-4.18-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: Revert "PM / runtime: Fixup reference counting of device link suppliers at probe" cpufreq: imx6q: check speed grades for i.MX6ULL cpufreq: governors: Fix long idle detection logic in load calculation cpufreq: intel_pstate: enable boost for Skylake Xeon PM / wakeup: Export wakeup_count instead of event_count via sysfs PM / Domains: Add dev_pm_domain_attach_by_id() to manage multi PM domains PM / Domains: Add support for multi PM domains per device to genpd PM / Domains: Split genpd_dev_pm_attach() PM / Domains: Don't attach devices in genpd with multi PM domains PM / Domains: dt: Allow power-domain property to be a list of specifiers cpufreq: intel_pstate: New sysfs entry to control HWP boost cpufreq: intel_pstate: HWP boost performance on IO wakeup cpufreq: intel_pstate: Add HWP boost utility and sched util hooks cpufreq: ti-cpufreq: Use devres managed API in probe() cpufreq: ti-cpufreq: Fix an incorrect error return value cpufreq: ACPI: make function acpi_cpufreq_fast_switch() static cpufreq: kryo: allow building as a loadable module cpupower : Fix header name to read idle state name cpupower: fix spelling mistake: "logilename" -> "logfilename"
