In order to safely remove PM domains there are a few changes that need to be
made to ensure that no one is holding an external reference to a PM domain
after it has been removed. One solution, implemented here, solves this by
eliminating external references to PM domain.

Changes from V1:
- Added test when removing a PM domain to ensure the PM domain provider
  has been removed.
- Re-organised patches 8-10 so that patch #8 adds the code to verify if
  the provider is present, patch #9 adds basic support for removing PM
  domains and patch #10 adds support for removing PM domains by provider.

Changes from initial RFC:
- Renamed functions made static per Ulf's feedback.
- Added patch to clean-up provider/xlate APIs per Ulf's feedback
- Re-worked and simplified the association between PM domains and PM
  domain providers. Dropped the 'provider_data' variable from the
  generic_pm_domain structure in favour of using the fwnode_handle.
- Split patch for removing PM domains into multiple patches per Ulf's
  feedback.

Jon Hunter (10):
  PM / Domains: Add new helper functions for device-tree
  ARM: EXYNOS: Remove calls to of_genpd_get_from_provider()
  staging: board: Remove calls to of_genpd_get_from_provider()
  PM / Domains: Don't expose generic_pm_domain structure to clients
  PM / Domains: Don't expose xlate and provider helper functions
  PM / Domains: Verify the PM domain is present when adding a provider
  PM / Domains: Prepare for adding support to remove PM domains
  PM / Domains: Store the provider in the PM domain structure
  PM / Domains: Add support for removing PM domains
  PM / Domains: Add support for removing nested PM domains by provider

All applied.

I'll expose a branch containing them after they've spent a couple of days in
linux-next.

Thanks,
