Merge tag 'pm-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
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)" * tag 'pm-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (44 commits) platform/x86/intel/pmc: core: Report duration of time in HW sleep state platform/x86/intel/pmc: core: Always capture counters on suspend platform/x86/amd: pmc: Report duration of time in hw sleep state PM: Add sysfs files to represent time spent in hardware sleep state cpufreq: use correct unit when verify cur freq cpufreq: tegra194: add OPP support and set bandwidth cpufreq: amd-pstate: Make varaiable mode_state_machine static PM: core: Remove unnecessary (void *) conversions cpufreq: drivers with target_index() must set freq_table PM / devfreq: exynos-ppmu: Use devm_platform_get_and_ioremap_resource() OPP: Move required opps configuration to specialized callback OPP: Handle all genpd cases together in _set_required_opps() cpufreq: qcom-cpufreq-hw: Revert adding cpufreq qos dt-bindings: cpufreq: cpufreq-qcom-hw: Add QCM2290 dt-bindings: cpufreq: cpufreq-qcom-hw: Sanitize data per compatible dt-bindings: cpufreq: cpufreq-qcom-hw: Allow just 1 frequency domain cpufreq: Add SM7225 to cpufreq-dt-platdev blocklist cpufreq: qcom-cpufreq-hw: fix double IO unmap and resource release on exit cpufreq: mediatek: Raise proc and sram max voltage for MT7622/7623 cpufreq: mediatek: raise proc/sram max voltage for MT8516 ...
