      PM / Domains: Support for generic I/O PM domains (v8) · f721889f
      Rafael J. Wysocki authored
      Introduce common headers, helper functions and callbacks allowing
      platforms to use simple generic power domains for runtime power
      management.
      
      Introduce struct generic_pm_domain to be used for representing
      power domains that each contain a number of devices and may be
      parent domains or subdomains with respect to other power domains.
      Among other things, this structure includes callbacks to be
      provided by platforms for performing specific tasks related to
      power management (i.e. ->stop_device() may disable a device's
      clocks, while ->start_device() may enable them, ->power_off() is
      supposed to remove power from the entire power domain
      and ->power_on() is supposed to restore it).
      
      Introduce functions that can be used as power domain runtime PM
      callbacks, pm_genpd_runtime_suspend() and pm_genpd_runtime_resume(),
      as well as helper functions for the initialization of a power
      domain represented by a struct generic_power_domain object,
      adding a device to or removing a device from it and adding or
      removing subdomains.
      
      Introduce configuration option CONFIG_PM_GENERIC_DOMAINS to be
      selected by the platforms that want to use the new code.

      PM: subsys_data in struct dev_pm_info need not depend on RM_RUNTIME · dc6e4e56
      Rafael J. Wysocki authored
      The subsys_data field of struct dev_pm_info, introduced by commit
      1d2b71f6 (PM / Runtime: Add subsystem
      data field to struct dev_pm_info), is going to be used even if
      CONFIG_PM_RUNTIME is not set, so move it from under the #ifdef.

      PM / Domains: Rename struct dev_power_domain to struct dev_pm_domain · 564b905a
      Rafael J. Wysocki authored
      The naming convention used by commit 7538e3db6e015e890825fbd9f86599b
      (PM: Add support for device power domains), which introduced the
      struct dev_power_domain type for representing device power domains,
      evidently confuses some developers who tend to think that objects
      of this type must correspond to "power domains" as defined by
      hardware, which is not the case.  Namely, at the kernel level, a
      struct dev_power_domain object can represent arbitrary set of devices
      that are mutually dependent power management-wise and need not belong
      to one hardware power domain.  To avoid that confusion, rename struct
      dev_power_domain to struct dev_pm_domain and rename the related
      pointers in struct device and struct pm_clk_notifier_block from
      pwr_domain to pm_domain.

      PM / Runtime: Update documentation regarding driver removal · f5da24db
      Rafael J. Wysocki authored
      Commit e1866b33 (PM / Runtime: Rework
      runtime PM handling during driver removal) forgot to update the
      documentation in Documentation/power/runtime_pm.txt to match the new
      code in drivers/base/dd.c.  Update that documentation to match the
      code it describes.

      PM: Documentation: fix typo: pm_runtime_idle_sync() doesn't exist. · 5efb54cc
      Kevin Hilman authored
      Replace reference to pm_runtime_idle_sync() in the driver core with
      pm_runtime_put_sync() which is used in the code.
