Merge branch 'pm-sleep'

* pm-sleep:
  PM: sleep: Drop dev_pm_skip_next_resume_phases()
  ACPI: PM: Drop unused function and function header
  ACPI: PM: Introduce "poweroff" callbacks for ACPI PM domain and LPSS
  ACPI: PM: Simplify and fix PM domain hibernation callbacks
  PCI: PM: Simplify bus-level hibernation callbacks
  PM: ACPI/PCI: Resume all devices during hibernation
  kernel: power: swap: use kzalloc() instead of kmalloc() followed by memset()
  PM: sleep: Update struct wakeup_source documentation
  drivers: base: power: remove wakeup_sources_stats_dentry variable
  PM: suspend: Rename pm_suspend_via_s2idle()
  PM: sleep: Show how long dpm_suspend_start() and dpm_suspend_end() take
  PM: hibernate: powerpc: Expose pfn_is_nosave() prototype
