[GIT PULL] Power management fixes for v6.15-rc3

[Rafael J. Wysocki]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-6.15-rc3

with top-most commit f3b25a1b48191048e2f190d878fc3175fc08ffaa

 Merge branch 'pm-docs'

on top of commit 8ffd015db85fea3e15a77027fda6c02ced4d2444

 Linux 6.15-rc2

to receive power management fixes for 6.15-rc3.

These are mostly cpufreq fixes, some of which address recent regressions
and some address older issues that have come to light during the last
two weeks, and a runtime PM documentation correction:

 - Fix the performance-to-frequency scaling factor computation on
   systems using HWP in the intel_pstate driver after a recent incorrect
   update of it (Rafael Wysocki).

 - Fix the usage of the CPUFREQ_NEED_UPDATE_LIMITS cpufreq driver flag
   in the schedutil cpufreq governor after a recent update of it that
   has caused frequency limits changes to be missed sometimes (Rafael
   Wysocki).

 - Address some recently discovered synchronization issues related to
   frequency limits changes in the schedutil cpufreq governor and in
   the cpufreq core (Rafael Wysocki).

 - Fix ITMT support in the amd-pstate cpufreq driver so that it is
   enabled after asym priorities have been correctly initialized for
   all CPUs (K Prateek Nayak).

 - Fix changing min/max limits in the amd-pstate cpufreq driver while
   on the performance governor (Dhananjay Ugwekar).

 - Fix a function name in the runtime PM documentation that was
   previously incorrectly updated by mistake (Sakari Ailus).

Thanks!
