Merge branch 'pm-domains'

* pm-domains:
  PM / Domains: Fix include for PM_GENERIC_DOMAINS=n case
  PM / Domains: Provide a dummy dev_gpd_data() when generic domains are not used
  PM / Domains: Run late/early device suspend callbacks at the right time
  ARM: EXYNOS: Hook up power domains to generic power domain infrastructure
  PM / Domains: Add OF support
