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: ACPI: PM: Avoid using power resources if there are none for D0 cpufreq: CPPC: add SW BOOST support cpufreq: change '.set_boost' to act on one policy 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 opp: Update the bandwidth on OPP frequency changes opp: Add sanity checks in _read_opp_key() opp: Add support for parsing interconnect bandwidth cpufreq: tegra186: add CPUFREQ_NEED_INITIAL_FREQ_CHECK flag OPP: Add helpers for reading the binding properties dt-bindings: opp: Introduce opp-peak-kBps and opp-avg-kBps bindings
