Subject: [PATCH V2 00/10] PM / Domains: Add support for removing PM domains
Date: Mon, 12 Sep 2016 12:01:04 +0100 [thread overview]
Message-ID: <1473678074-15126-1-git-send-email-jonathanh@nvidia.com> (raw)
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
