Subject: [GIT PULL] Power management updates for v6.5-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-6.5-rc1

with top-most commit c89a27f4f8fbf4dcbaf1738b42b8c68e160d7cda

 Merge branch 'powercap'

on top of commit 45a3e24f65e90a047bef86f927ebdc4c710edaa1

 Linux 6.4-rc7

to receive power management updates for 6.5-rc1.

These add Intel TPMI ((Topology Aware Register and PM Capsule Interface)
support to the power capping subsystem, extend the intel_idle driver to
work in VM guests where MWAIT is not available, extend the system-wide
power management diagnostics, fix bugs and clean up code.

Specifics:

 - Introduce power capping core support for Intel TPMI (Topology Aware
   Register and PM Capsule Interface) and a TPMI interface driver for
   Intel RAPL (Zhang Rui, Dan Carpenter).

 - Fix CONFIG_IOSF_MBI dependency in the Intel RAPL power capping
   driver (Zhang Rui).

 - Fix invalid initialization for pl4_supported field in the Intel RAPL
   power capping driver (Sumeet Pawnikar).

 - Clean up the intel_idle driver, make it work with VM guests that
   cannot use the MWAIT instruction and address the case in which the
   host may enter a deep idle state when the guest is idle (Arjan van
   de Ven).

 - Prevent cpufreq drivers that provide the ->adjust_perf() callback
   without a ->fast_switch() one which is used as a fallback from the
   former in some cases (Wyes Karny).

 - Fix some issues related to the AMD P-state cpufreq driver (Mario
   Limonciello, Wyes Karny).

 - Fix the energy_performance_preference attribute handling in the
   intel_pstate driver in passive mode (Tero Kristo).

 - Fix the handling of pm_suspend_target_state when CONFIG_PM is unset
   (Kai-Heng Feng).

 - Correct spelling mistake in a comment in the hibernation code (Wang
   Honghui).

 - Add arch_resume_nosmt() prototype to avoid a "missing prototypes"
   build warning (Arnd Bergmann).

 - Restrict pm_pr_dbg() to system-wide power transitions and use it in
   a few additional places (Mario Limonciello).

 - Drop verification of in-params from genpd_add_device() and ensure
   that all of its callers will do it (Ulf Hansson).

 - Prevent possible integer overflows from occurring in
   genpd_parse_state() (Nikita Zhandarovich).

 - Reorder fields in 'struct devfreq_dev_status' to reduce its size
   somewhat (Christophe JAILLET).

 - Ensure that the Exynos PPMU driver is already loaded before the
   Exynos Bus driver starts probing so as to avoid a possible freeze
   loading of the kernel modules (Marek Szyprowski).

 - Fix variable deferencing before NULL check in the mtk-cci devfreq
   driver (Sukrut Bellary).

Thanks!
