PM: Eliminate CONFIG_PM_RUNTIME

2014-12-19T21:55:06+00:00

Having switched over all of the users of CONFIG_PM_RUNTIME to use
CONFIG_PM directly, turn the latter into a user-selectable option
and drop the former entirely from the tree.

PM: Drop CONFIG_PM_RUNTIME from the driver core

2014-12-03T23:46:58+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 quite a few
depend on CONFIG_PM or even may be dropped entirely in some cases.

Replace CONFIG_PM_RUNTIME with CONFIG_PM in the PM core code.

PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected

2014-11-18T22:41:40+00:00

The number of and dependencies between high-level power management
Kconfig options make life much harder than necessary.  Several
conbinations of them have to be tested and supported, even though
some of those combinations are very rarely used in practice (if
they are used in practice at all).  Moreover, the fact that we
have separate independent Kconfig options for runtime PM and
system suspend is a serious obstacle for integration between
the two frameworks.

To overcome these difficulties, always select PM_RUNTIME if PM_SLEEP
is set.  Among other things, this will allow system suspend callbacks
provided by bus types and device drivers to rely on the runtime PM
framework regardless of the kernel configuration.

PM: Kconfig: fix unmet dependency for CPU_PM

2014-11-18T01:51:17+00:00

If BL_SWITCHER is enabled but SUSPEND and CPU_IDLE is not enabled
we are getting following config warning.

warning: (BL_SWITCHER) selects CPU_PM which has unmet direct
dependencies (SUSPEND || CPU_IDLE)

It has been noticed that CPU_PM dependencies in this file are not really
required so let's remove these dependencies from CPU_PM.

PM / hibernate: Deletion of an unnecessary check before the function call "vfree"

2014-11-18T01:49:40+00:00

The vfree() function performs also input parameter validation. Thus the test
around the call is not needed.

This issue was detected by using the Coccinelle software.

PM / Runtime: Kconfig: move ia64 dependency to arch/ia64/Kconfig

2014-11-14T23:39:56+00:00

The IA64_HP_SIM dependency on PM_RUNTIME should be done in the arch
Kconfig instead of in the PM core.  Move it accordingly.

NOTE: arch/ia64/Kconfig currently does a 'select PM', which since
commit 1eb208aea317 (PM: Make CONFIG_PM depend on (CONFIG_PM_SLEEP ||
CONFIG_PM_RUNTIME)) is effectively a noop unless PM_SLEEP or
PM_RUNTIME are set elsewhere.
