Subject: [GIT PULL] Power management fixes for v6.1-rc3

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-6.1-rc3

with top-most commit 6f257934ed6170ed0094149e0e1bac09f7997103

 Merge branches 'pm-sleep', 'pm-domains' and 'pm-tools'

on top of commit 247f34f7b80357943234f93f247a1ae6b6c3a740

 Linux 6.1-rc2

to receive power management fixes for 6.1-rc3.

These make the intel_pstate driver work as expected on all hybrid
platforms to date (regardless of possible platform firmware issues),
fix hybrid sleep on systems using suspend-to-idle by default, make
the generic power domains code handle disabled idle states properly
and update pm-graph.

Specifics:

 - Make intel_pstate use what is known about the hardware instead of
   relying on information from the platform firmware (ACPI CPPC in
   particular) to establish the relationship between the HWP CPU
   performance levels and frequencies on all hybrid platforms
   available to date (Rafael Wysocki).

 - Allow hybrid sleep to use suspend-to-idle as a system suspend method
   if it is the current suspend method of choice (Mario Limonciello).

 - Fix handling of unavailable/disabled idle states in the generic
   power domains code (Sudeep Holla).

 - Update the pm-graph suite of utilities to version 5.10 which is
   fixes-mostly and does not add any new features (Todd Brandt).

Thanks!
