Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm-5.7-rc1-2
with top-most commit 54032b863b56b0e5313bfcd6ef0818943c59c4f4
Merge branches 'pm-sleep' and 'pm-cpufreq'
on top of commit 2ce94bc4e056d3e48291aac87a95ebd2a86348ba
Merge tag 'pnp-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
to receive additional power management updates for 5.7-rc1.
These fix a corner-case suspend-to-idle wakeup issue on systems where the ACPI SCI is shared with another wakeup source, add a kernel command line option to set pm_debug_messages via the kernel command line, add a document desctibing system-wide suspend and resume code flows, modify cpufreq Kconfig to choose schedutil as the preferred governor by default in a couple of cases and do some assorted cleanups.
Specifics:
- Fix corner-case suspend-to-idle wakeup issue on systems where the ACPI SCI is shared with another wakeup source (Hans de Goede).
- Add document describing system-wide suspend and resume code flows to the admin guide (Rafael Wysocki).
- Add kernel command line option to set pm_debug_messages (Chen Yu).
- Choose schedutil as the preferred scaling governor by default on ARM big.LITTLE systems and on x86 systems using the intel_pstate driver in the passive mode (Linus Walleij, Rafael Wysocki).
- Drop racy and redundant checks from the PM core's device_prepare() routine (Rafael Wysocki).
- Make resume from hibernation take the hibernation_restore() return value into account (Dexuan Cui).
Thanks!
