  - Extend support for wakeirq to callback wrappers used during system
    suspend and resume (Ulf Hansson).
 
  - Defer waiting for device probe before loading a hibernation image
    till the first actual device access to avoid possible deadlocks
    reported by syzbot (Tetsuo Handa).

    Helgaas).
 
  - Add Raptor Lake-P to the list of processors supported by the Intel
    RAPL driver (George D Sworo).
 
  - Add Alder Lake-N and Raptor Lake-P to the list of processors for
    which Power Limit4 is supported in the Intel RAPL driver (Sumeet
    Pawnikar).
 
  - Make pm_genpd_remove() check genpd_debugfs_dir against NULL before
    attempting to remove it (Hsin-Yi Wang).
 
  - Change the Energy Model code to represent power in micro-Watts and
    adjust its users accordingly (Lukasz Luba).
 
  - Add new devfreq driver for Mediatek CCI (Cache Coherent
    Interconnect) (Johnson Wang).
 
  - Convert the Samsung Exynos SoC Bus bindings to DT schema of
    exynos-bus.c (Krzysztof Kozlowski).
 
  - Address kernel-doc warnings by adding the description for unused
    fucntion parameters in devfreq core (Mauro Carvalho Chehab).
 
  - Use NULL to pass a null pointer rather than zero according to the
    function propotype in imx-bus.c (Colin Ian King).
 
  - Print error message instead of error interger value in
    tegra30-devfreq.c (Dmitry Osipenko).
 
  - Add checks to prevent setting negative frequency QoS limits for
    CPUs (Shivnandan Kumar).
 
  - Update the pm-graph suite of utilities to the latest revision 5.9
    including multiple improvements (Todd Brandt).
 
  - Drop pme_interrupt reference from the PCI power management
    documentation (Mario Limonciello).

Pull power management updates from Rafael Wysocki:
 "These are mostly minor improvements all over including new CPU IDs for
  the Intel RAPL driver, an Energy Model rework to use micro-Watt as the
