Merge tag 'pm-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki: "These rework the system-wide PM driver flags, make runtime switching of cpuidle governors easier, improve the user space hibernation interface code, add intel-speed-select interface documentation, add more debug messages to the ACPI code handling suspend to idle, update the cpufreq core and drivers, fix a minor issue in the cpuidle core and update two cpuidle drivers, improve the PM-runtime framework, update the Intel RAPL power capping driver, update devfreq core and drivers, and clean up the cpupower utility. Specifics: - Rework the system-wide PM driver flags to make them easier to understand and use and update their documentation (Rafael Wysocki, Alan Stern). - Allow cpuidle governors to be switched at run time regardless of the kernel configuration and update the related documentation accordingly (Hanjun Guo). - Improve the resume device handling in the user space hibernarion interface code (Domenico Andreoli). - Document the intel-speed-select sysfs interface (Srinivas Pandruvada). - Make the ACPI code handing suspend to idle print more debug messages to help diagnose issues with it (Rafael Wysocki). - Fix a helper routine in the cpufreq core and correct a typo in the struct cpufreq_driver kerneldoc comment (Rafael Wysocki, Wang Wenhu). - Update cpufreq drivers: - Make the intel_pstate driver start in the passive mode by default on systems without HWP (Rafael Wysocki). - Add i.MX7ULP support to the imx-cpufreq-dt driver and add i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan). - Convert the qoriq cpufreq driver to a platform one, make the platform code create a suitable device object for it and add platform dependencies to it (Mian Yousaf Kaukab, Geert Uytterhoeven). - Fix wrong compatible binding in the qcom driver (Ansuel Smith). - Build the omap driver by default for ARCH_OMAP2PLUS (Anders Roxell). - Add r8a7742 SoC support to the dt cpufreq driver (Lad Prabhakar). - Update cpuidle core and drivers: - Fix three reference count leaks in error code paths in the cpuidle core (Qiushi Wu). - Convert Qualcomm SPM to a generic cpuidle driver (Stephan Gerhold). - Fix up the execution order when entering a domain idle state in the PSCI driver (Ulf Hansson). - Fix a reference counting issue related to clock management and clean up two oddities in the PM-runtime framework (Rafael Wysocki, Andy Shevchenko). - Add ElkhartLake support to the Intel RAPL power capping driver and remove an unused local MSR definition from it (Jacob Pan, Sumeet Pawnikar). - Update devfreq core and drivers: - Replace strncpy() with strscpy() in the devfreq core and use lockdep asserts instead of manual checks for a locked mutex in it (Dmitry Osipenko, Krzysztof Kozlowski). - Add a generic imx bus scaling driver and make it register an interconnect device (Leonard Crestez, Gustavo A. R. Silva). - Make the cpufreq notifier in the tegra30 driver take boosting into account and delete an unuseful error message from that driver (Dmitry Osipenko, Markus Elfring). - Remove unneeded semicolon from the cpupower code (Zou Wei)" * tag 'pm-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (51 commits) cpuidle: Fix three reference count leaks PM: runtime: Replace pm_runtime_callbacks_present() PM / devfreq: Use lockdep asserts instead of manual checks for locked mutex PM / devfreq: imx-bus: Fix inconsistent IS_ERR and PTR_ERR PM / devfreq: Replace strncpy with strscpy PM / devfreq: imx: Register interconnect device PM / devfreq: Add generic imx bus scaling driver PM / devfreq: tegra30: Delete an error message in tegra_devfreq_probe() PM / devfreq: tegra30: Make CPUFreq notifier to take into account boosting PM: hibernate: Restrict writes to the resume device PM: runtime: clk: Fix clk_pm_runtime_get() error path cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driver ACPI: EC: PM: s2idle: Extend GPE dispatching debug message ACPI: PM: s2idle: Print type of wakeup debug messages powercap: RAPL: remove unused local MSR define PM: runtime: Make clear what we do when conditions are wrong in rpm_suspend() Documentation: admin-guide: pm: Document intel-speed-select PM: hibernate: Split off snapshot dev option PM: hibernate: Incorporate concurrency handling Documentation: ABI: make current_governer_ro as a candidate for removal ...
