Subject: [GIT PULL] Power management fixes for v5.9-rc4

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.9-rc4

with top-most commit f7ce2c3afc938b7d743ee8e5563560c04e17d7be

 Merge branch 'pm-cpufreq'

on top of commit f75aef392f869018f78cfedf3c320a6b3fcfda6b

 Linux 5.9-rc3

to receive power management fixes for 5.9-rc4.

These fix reference counting in the operating performance points
(OPP) framework and address a few intel_pstate driver issues,
mostly related to switching driver operation modes and similar
with hardware-managed P-states (HWP) enabled.

Specifics:

 - Fix reference counting of operating performance points (OPP)
   tables (Viresh Kumar).

 - Address intel_pstate driver interface issues, mostly related
   to switching operation modes and handling CPU offline and
   online and system-wide suspend/resume with hardware-managed
   P-states (HWP) enabled (Rafael Wysocki).

 - Fix the maximum frequency computation in the intel_pstate driver
   with turbo P-states disabled by the platform firmware and HWP
   enabled (Francisco Jerez).

Thanks!
