Merge branches 'pm-core', 'pm-clk', 'pm-domains' and 'pm-pci'

* pm-core:
  PM / runtime: Asynchronous "idle" in pm_runtime_allow()
  PM / runtime: print error when activating a child to unactive parent

* pm-clk:
  PM / clk: Add support for adding a specific clock from device-tree
  PM / clk: export symbols for existing pm_clk_<...> API fcns

* pm-domains:
  PM / Domains: Convert pm_genpd_init() to return an error code
  PM / Domains: Stop/start devices during system PM suspend/resume in genpd
  PM / Domains: Allow runtime PM during system PM phases
  PM / Runtime: Avoid resuming devices again in pm_runtime_force_resume()
  PM / Domains: Remove redundant pm_request_idle() call in genpd
  PM / Domains: Remove redundant wrapper functions for system PM
  PM / Domains: Allow genpd to power on during system PM phases

* pm-pci:
  PCI / PM: check all fields in pci_set_platform_pm()
