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)"
