Pull power management updates from Rafael Wysocki:
 "These update several cpufreq drivers and the cpufreq core, add sysfs
  interface for exposing the time really spent in the platform low-power
  state during suspend-to-idle, update devfreq (core and drivers) and
  the pm-graph suite of tools and clean up code.

  Specifics:

   - Fix the frequency unit in cpufreq_verify_current_freq checks()
     Sanjay Chandrashekara)

   - Make mode_state_machine in amd-pstate static (Tom Rix)

   - Make the cpufreq core require drivers with target_index() to set
     freq_table (Viresh Kumar)

   - Fix typo in the ARM_BRCMSTB_AVS_CPUFREQ Kconfig entry (Jingyu Wang)

   - Use of_property_read_bool() for boolean properties in the pmac32
     cpufreq driver (Rob Herring)

   - Make the cpufreq sysfs interface return proper error codes on
     obviously invalid input (qinyu)

   - Add guided autonomous mode support to the AMD P-state driver (Wyes
     Karny)

   - Make the Intel P-state driver enable HWP IO boost on all server
     platforms (Srinivas Pandruvada)

   - Add opp and bandwidth support to tegra194 cpufreq driver (Sumit
     Gupta)

   - Use of_property_present() for testing DT property presence (Rob
     Herring)

   - Remove MODULE_LICENSE in non-modules (Nick Alcock)

   - Add SM7225 to cpufreq-dt-platdev blocklist (Luca Weiss)

   - Optimizations and fixes for qcom-cpufreq-hw driver (Krzysztof
     Kozlowski, Konrad Dybcio, and Bjorn Andersson)

   - DT binding updates for qcom-cpufreq-hw driver (Konrad Dybcio and
     Bartosz Golaszewski)

   - Updates and fixes for mediatek driver (Jia-Wei Chang and
     AngeloGioacchino Del Regno)

   - Use of_property_present() for testing DT property presence in the
     cpuidle code (Rob Herring)

   - Drop unnecessary (void *) conversions from the PM core (Li zeming)

   - Add sysfs files to represent time spent in a platform sleep state
     during suspend-to-idle and make AMD and Intel PMC drivers use them
     Mario Limonciello)

   - Use of_property_present() for testing DT property presence (Rob
     Herring)

   - Add set_required_opps() callback to the 'struct opp_table', to make
     the code paths cleaner (Viresh Kumar)

   - Update the pm-graph siute of utilities to v5.11 with the following
     changes:
       * New script which allows users to install the latest pm-graph
         from the upstream github repo.
       * Update all the dmesg suspend/resume PM print formats to be able
         to process recent timelines using dmesg only.
       * Add ethtool output to the log for the system's ethernet device
         if ethtool exists.
       * Make the tool more robustly handle events where mangled dmesg
         or ftrace outputs do not include all the requisite data.

   - Make the sleepgraph utility recognize "CPU killed" messages (Xueqin
     Luo)

   - Remove unneeded SRCU selection in Kconfig because it's always set
     from devfreq core (Paul E. McKenney)

   - Drop of_match_ptr() macro from exynos-bus.c because this driver is
     always using the DT table for driver probe (Krzysztof Kozlowski)

   - Use the preferred of_property_present() instead of the low-level
     of_get_property() on exynos-bus.c (Rob Herring)

   - Use devm_platform_get_and_ioream_resource() in exyno-ppmu.c (Yang
     Li)"
