Subject: [GIT PULL] Power management updates for v5.13-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.13-rc1
with top-most commit 59e2c959f20f9f255a42de52cde54a2962fb726f
Merge branches 'pm-docs' and 'pm-tools'
on top of commit e49d033bddf5b565044e2abe4241353959bc9120
Linux 5.12-rc6
to receive power management updates for 5.13-rc1.
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 account 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 issues 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 operation 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).
Thanks!
