Merge tag 'pm-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
 "From the functional perspective, the most significant change here is
  the addition of support for Energy Models that can be updated
  dynamically at run time.

  There is also the addition of LZ4 compression support for hibernation,
  the new preferred core support in amd-pstate, new platforms support in
  the Intel RAPL driver, new model-specific EPP handling in intel_pstate
  and more.

  Apart from that, the cpufreq default transition delay is reduced from
  10 ms to 2 ms (along with some related adjustments), the system
  suspend statistics code undergoes a significant rework and there is a
  usual bunch of fixes and code cleanups all over.

  Specifics:

   - Allow the Energy Model to be updated dynamically (Lukasz Luba)

   - Add support for LZ4 compression algorithm to the hibernation image
     creation and loading code (Nikhil V)
