Merge tag 'pm-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki: "These add some new hardware support (for example, IceLake-D idle states in intel_idle), fix some issues (for example, the handling of negative "sleep length" values in cpuidle governors), add new functionality to the existing drivers (for example, scale-invariance support in the ACPI CPPC cpufreq driver) and clean up code all over. Specifics: - Add idle states table for IceLake-D to the intel_idle driver and update IceLake-X C6 data in it (Artem Bityutskiy). - Fix the C7 idle state on Tegra114 in the tegra cpuidle driver and drop the unused do_idle() firmware call from it (Dmitry Osipenko). - Fix cpuidle-qcom-spm Kconfig entry (He Ying). - Fix handling of possible negative tick_nohz_get_next_hrtimer() return values of in cpuidle governors (Rafael Wysocki). - Add support for frequency-invariance to the ACPI CPPC cpufreq driver and update the frequency-invariance engine (FIE) to use it as needed (Viresh Kumar). - Simplify the default delay_us setting in the ACPI CPPC cpufreq driver (Tom Saeger). - Clean up frequency-related computations in the intel_pstate cpufreq driver (Rafael Wysocki). - Fix TBG parent setting for load levels in the armada-37xx cpufreq driver and drop the CPU PM clock .set_parent method for armada-37xx (Marek Behún). - Fix multiple issues in the armada-37xx cpufreq driver (Pali Rohár). - Fix handling of dev_pm_opp_of_cpumask_add_table() return values in cpufreq-dt to take the -EPROBE_DEFER one into acconut as appropriate (Quanyang Wang). - Fix format string in ia64-acpi-cpufreq (Sergei Trofimovich). - Drop the unused for_each_policy() macro from cpufreq (Shaokun Zhang). - Simplify computations in the schedutil cpufreq governor to avoid unnecessary overhead (Yue Hu). - Fix typos in the s5pv210 cpufreq driver (Bhaskar Chowdhury). - Fix cpufreq documentation links in Kconfig (Alexander Monakov). - Fix PCI device power state handling in pci_enable_device_flags() to avoid issuse in some cases when the device depends on an ACPI power resource (Rafael Wysocki). - Add missing documentation of pm_runtime_resume_and_get() (Alan Stern). - Add missing static inline stub for pm_runtime_has_no_callbacks() to pm_runtime.h and drop the unused try_to_freeze_nowarn() definition (YueHaibing). - Drop duplicate struct device declaration from pm.h and fix a structure type declaration in intel_rapl.h (Wan Jiabing). - Use dev_set_name() instead of an open-coded equivalent of it in the wakeup sources code and drop a redundant local variable initialization from it (Andy Shevchenko, Colin Ian King). - Use crc32 instead of md5 for e820 memory map integrity check during resume from hibernation on x86 (Chris von Recklinghausen). - Fix typos in comments in the system-wide and hibernation support code (Lu Jialin). - Modify the generic power domains (genpd) code to avoid resuming devices in the "prepare" phase of system-wide suspend and hibernation (Ulf Hansson). - Add Hygon Fam18h RAPL support to the intel_rapl power capping driver (Pu Wen). - Add MAINTAINERS entry for the dynamic thermal power management (DTPM) code (Daniel Lezcano). - Add devm variants of operating performance points (OPP) API functions and switch over some users of the OPP framework to the new resource-managed API (Yangtao Li and Dmitry Osipenko). - Update devfreq core: * Register devfreq devices as cooling devices on demand (Daniel Lezcano). * Add missing unlock opeation in devfreq_add_device() (Lukasz Luba). * Use the next frequency as resume_freq instead of the previous frequency when using the opp-suspend property (Dong Aisheng). * Check get_dev_status in devfreq_update_stats() (Dong Aisheng). * Fix set_freq path for the userspace governor in Kconfig (Dong Aisheng). * Remove invalid description of get_target_freq() (Dong Aisheng). - Update devfreq drivers: * imx8m-ddrc: Remove imx8m_ddrc_get_dev_status() and unneeded of_match_ptr() (Dong Aisheng, Fabio Estevam). * rk3399_dmc: dt-bindings: Add rockchip,pmu phandle and drop references to undefined symbols (Enric Balletbo i Serra, Gaël PORTAY). * rk3399_dmc: Use dev_err_probe() to simplify the code (Krzysztof Kozlowski). * imx-bus: Remove unneeded of_match_ptr() (Fabio Estevam). - Fix kernel-doc warnings in three places (Pierre-Louis Bossart). - Fix typo in the pm-graph utility code (Ricardo Ribalda)" * tag 'pm-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (74 commits) PM: wakeup: remove redundant assignment to variable retval PM: hibernate: x86: Use crc32 instead of md5 for hibernation e820 integrity check cpufreq: Kconfig: fix documentation links PM: wakeup: use dev_set_name() directly PM: runtime: Add documentation for pm_runtime_resume_and_get() cpufreq: intel_pstate: Simplify intel_pstate_update_perf_limits() cpufreq: armada-37xx: Fix module unloading cpufreq: armada-37xx: Remove cur_frequency variable cpufreq: armada-37xx: Fix determining base CPU frequency cpufreq: armada-37xx: Fix driver cleanup when registration failed clk: mvebu: armada-37xx-periph: Fix workaround for switching from L1 to L0 clk: mvebu: armada-37xx-periph: Fix switching CPU freq from 250 Mhz to 1 GHz cpufreq: armada-37xx: Fix the AVS value for load L1 clk: mvebu: armada-37xx-periph: remove .set_parent method for CPU PM clock cpufreq: armada-37xx: Fix setting TBG parent for load levels cpuidle: Fix ARM_QCOM_SPM_CPUIDLE configuration cpuidle: tegra: Remove do_idle firmware call cpuidle: tegra: Fix C7 idling state on Tegra114 PM: sleep: fix typos in comments cpufreq: Remove unused for_each_policy macro ...
