drivers: sh: remove boilerplate code and use USE_PM_CLK_RUNTIME_OPS

2015-05-12T21:55:38+00:00

USE_PM_CLK_RUNTIME_OPS is introduced so we don't repeat the same code
to do runtime_suspend and runtime_resume across users of PM clocks.
Use it to remove the boilerplate code.

drivers: sh: Disable PM runtime for multi-platform r8a73a4 with genpd

2015-04-27T04:08:13+00:00

If the default PM domain using PM_CLK is used for PM runtime, the real PM
domain(s) cannot be registered from DT later.

Hence do not enable it when running a multi-platform kernel with genpd
support on an r8a73a4. The R-Mobile PM domain driver will take care of
PM runtime management of the module clocks.

The default PM domain is still needed for:
  - platforms without genpd support,
  - the legacy (non-DT) case, where genpd may take over later, except
    for the C5 "always on" PM domain.

drivers: sh / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM

2014-12-05T02:08:24+00:00

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.

Replace CONFIG_PM_RUNTIME with CONFIG_PM in drivers/sh/pm_runtime.c.

Since genpd at late init, will try to disable unused PM domains we
don't need to do it from here as well.

drivers: sh: pm_runtime implementation needs to suspend and resume devices

2014-05-26T01:45:06+00:00

If we override the platform bus calls for pm_runtime then we end up
with the calls to the devices' suspend and resume methods ignored
in favour of the bus ones.

Change to calling the pm_runtime calls to suspend and resume the
devices specifically in the drivers/sh/pm_runtime.c implementation
to allow any device that may want to run power management to do so.

Note, all the current sh driver implementations do not use their
own power management code so this is not a major implementation
issues.

This also brings the implementation into line with the versions
used by the Davinci and Keystone PM domain code, so once fully
tested these implementations could be merged together.

drivers: sh: pm_runtime does not need idle callback

2014-05-26T01:44:54+00:00

In the runtime_pm idle callback the code assumes that a NULL .runtime_idle
entry is the same as a .runtime_idle entry that returns 0 as a result. This
means the entry in drivers/sh/pm_runtime can be removed in favour of just
leaving the entry NULL.
