Merge tag 'pm-5.8-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates from Rafael Wysocki:
"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)"
* tag 'pm-5.8-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:

PM: hibernate: Add __init annotation to swsusp_header_init()
opp: Don't parse icc paths unnecessarily
opp: Remove bandwidth votes when target_freq is zero
opp: core: add regulators enable and disable
opp: Reorder the code for !target_freq case
opp: Expose bandwidth information via debugfs
cpufreq: dt: Add support for interconnect bandwidth scaling
