2016-01-08PM / Domains: add setter for dev.pm_domainTomeu Vizoso1-2/+3
Adds a function that sets the pointer to dev_pm_domain in struct device and that warns if the device has already finished probing. The reason why we want to enforce that is because in the general case that can cause problems and also that we can simplify code quite a bit if we can always assume that. This patch also changes all current code that directly sets the dev.pm_domain pointer.

2014-12-05misc / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PMRafael J. Wysocki1-5/+3
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.

2014-07-18mei: don't schedule suspend in pm idleAlexander Usyskin1-1/+1
Calling pm_schedule_suspend from the runtime pm idle callback may reschedule existing timer, thus in case of frequent runtime rpm idle call the suspend maybe starved. Instead we call pm_runtime_autosuspend which is checking if the timer is already charged. An example is monitoring device pci config space. Pci config sysfs handlers calls pci_config_pm_runtime_put/get helpers which in turns calls to device idle callback Cc: stable@vger.kernel.org # 3.15+ Signed-off-by: Alexander Usyskin <alexander.usyskin@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

For non wakeable devices we can't use pci runtime framework as we are not able to wakeup from D3 states.
