Subject: [GIT PULL] More power management updates for v5.8-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.8-rc1-2

with top-most commit 50dd154ed7b17a8b3a1983fc32a8e41d4cc4211a

 Merge branches 'pm-cpufreq' and 'pm-acpi'

on top of commit 355ba37d756c38962fe9bb616f5f48eb12a7e11e

 Merge tag 'pm-5.8-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive more power management updates for 5.8-rc1.

These are operating performance points (OPP) framework updates mostly,
including support for interconnect bandwidth in the OPP core, plus a
few cpufreq changes, including boost support in the CPPC cpufreq
driver, an ACPI device power management fix and a hibernation code
cleanup.

Specifics:

 - Add support for interconnect bandwidth to the OPP core (Georgi
   Djakov, Saravana Kannan, Sibi Sankar, Viresh Kumar).

 - Add support for regulator enable/disable to the OPP core (Kamil
   Konieczny).

 - Add boost support to the CPPC cpufreq driver (Xiongfeng Wang).

 - Make the tegra186 cpufreq driver set the
   CPUFREQ_NEED_INITIAL_FREQ_CHECK flag (Mian Yousaf Kaukab).

 - Prevent the ACPI power management from using power resources
   with devices where the list of power resources for power state
   D0 (full power) is missing (Rafael Wysocki).

 - Annotate a hibernation-related function with __init (Christophe
   JAILLET).

Thanks!
