Merge branch 'power-domains' into for-linus

* power-domains:
  PM: Fix build issue in clock_ops.c for CONFIG_PM_RUNTIME unset
  PM: Revert "driver core: platform_bus: allow runtime override of dev_pm_ops"
  OMAP1 / PM: Use generic clock manipulation routines for runtime PM
  PM / Runtime: Generic clock manipulation rountines for runtime PM (v6)
  PM / Runtime: Add subsystem data field to struct dev_pm_info
  OMAP2+ / PM: move runtime PM implementation to use device power domains
  PM / Platform: Use generic runtime PM callbacks directly
  shmobile: Use power domains for platform runtime PM
  PM: Export platform bus type's default PM callbacks
  PM: Make power domain callbacks take precedence over subsystem ones
