Subject: [GIT PULL] Power management updates for v5.3-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.3-rc1
with top-most commit 586a07dca8c51b966960d1f0d8be9c27d7e0a95c
Merge branch 'pm-cpufreq'
on top of commit 6fbc7275c7a9ba97877050335f290341a1fd8dbf
Linux 5.2-rc7
to receive power management updates for 5.3-rc1.
These update PCI and ACPI power management (improved handling of
ACPI power resources and PCIe link delays, fixes related to corner
cases, hibernation handling rework), fix and extend the operating
performance points (OPP) framework, add new cpufreq drivers for
Raspberry Pi and imx8m chips, update some other cpufreq drivers,
clean up assorted pieces of PM code and documentation and update
tools.
Specifics:
- Improve the handling of shared ACPI power resources in the PCI
bus type layer (Mika Westerberg).
- Make the PCI layer take link delays required by the PCIe spec
into account as appropriate and avoid polling devices in D3cold
for PME (Mika Westerberg).
- Fix some corner case issues in ACPI device power management and
in the PCI bus type layer, optimiza and clean up the handling of
runtime-suspended PCI devices during system-wide transitions to
sleep states (Rafael Wysocki).
- Rework hibernation handling in the ACPI core and the PCI bus type
to resume runtime-suspended devices before hibernation (which
allows some functional problems to be avoided) and fix some ACPI
power management issues related to hiberation (Rafael Wysocki).
- Extend the operating performance points (OPP) framework to support
a wider range of devices (Rajendra Nayak, Stehpen Boyd).
- Fix issues related to genpd_virt_devs and issues with platforms
using the set_opp() callback in the OPP framework (Viresh Kumar,
Dmitry Osipenko).
- Add new cpufreq driver for Raspberry Pi (Nicolas Saenz Julienne).
- Add new cpufreq driver for imx8m and imx7d chips (Leonard Crestez).
- Fix and clean up the pcc-cpufreq, brcmstb-avs-cpufreq, s5pv210,
and armada-37xx cpufreq drivers (David Arcari, Florian Fainelli,
Paweł Chmiel, YueHaibing).
- Clean up and fix the cpufreq core (Viresh Kumar, Daniel Lezcano).
- Fix minor issue in the ACPI system sleep support code and export
one function from it (Lenny Szubowicz, Dexuan Cui).
- Clean up assorted pieces of PM code and documentation (Kefeng Wang,
Andy Shevchenko, Bart Van Assche, Greg Kroah-Hartman, Fuqian Huang,
Geert Uytterhoeven, Mathieu Malaterre, Rafael Wysocki).
- Update the pm-graph utility to v5.4 (Todd Brandt).
- Fix and clean up the cpupower utility (Abhishek Goel, Nick Black).
Thanks!
