Merge tag 'pm-6.1-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management updates from Rafael Wysocki:
 "These update the turbostat utility, extend the macros used for
  defining device power management callbacks and add a diagnostic
  message to the generic power domains code.

  Specifics:

   - Add an error message to be printed when a power domain marked as
     "always on" is not actually on during initialization (Johan
     Hovold).

   - Extend macros used for defining power management callbacks to allow
     conditional exporting of noirq and late/early suspend/resume PM
     callbacks (Paul Cercueil).

   - Update the turbostat utility:
      - Add support for two new platforms (Zhang Rui).
      - Adjust energy unit for Sapphire Rapids (Zhang Rui).
      - Do not dump TRL if turbo is not supported (Artem Bityutskiy)"
