2015-03-23PM / domains: avoid potential oops in pm_genpd_remove_device()Russell King1-3/+1
pm_genpd_remove_device() tries hard to validate the generic PM domain passed to it, but the validation is not complete. dev->pm_domain contains a struct dev_pm_domain, which is the "base class" of generic PM domains. Other users of dev_pm_domains include stuff like vga_switheroo. Hence, a device could have a generic PM domain or a vga_switcheroo PM domain in dev->pm_domain. We need ot be certain that the PM domain is actually valid before we try to remove it. We can do this easily as we have a way to get the current validated generic PM domain for a struct device. This must match the generic PM domain being requested for removal. Convert the code to use this alternative validation method instead.

2015-03-22PM / domains: factor out code to get the generic PM domain from a struct deviceRussell King1-14/+32
The PM domain code contains two methods to get the generic PM domain for a struct device. One is dev_to_genpd() which is only safe when we know for certain that the device has a generic PM domain attached. The other is coded into genpd_dev_pm_detach() which ensures that the PM domain in the struct device is a generic PM domain (and so is safer). This commit factors out the safer version, documents it, and hides the unsafe dev_to_genpd(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Rafael J.

2015-03-22PM / domains: quieten down generic pm domainsRussell King1-4/+4
PM domains are rather noisy; scheduling behaviour can cause callbacks to take longer, which causes them to spit out a warning-level message each time a callback takes a little longer than the previous time. There really isn't a need for this, except when debugging.

2015-03-22PM / Domains: Sync runtime PM status with genpd after probeRussell King1-0/+12
Buses which currently supports attaching devices to their PM domains, will invoke the dev_pm_domain_attach() API from their ->probe() callbacks. During the attach procedure, genpd power up the PM domain. In those scenarios where the bus/driver don't need to access its device during probe, it may leave it in runtime PM suspended state since that's also the default state. In that way, no notifications through the runtime PM callbacks will reach the PM domain during probe. For genpd, the consequence from the above scenario means the PM domain will remain powered. Therefore, implement the struct dev_pm_domain's ->sync() callback, which is invoked from driver core after the bus/driver has probed the device. It allows genpd to power off the PM domain if it's unused.

2015-02-03PM / Domains: Handle errors from genpd's ->attach_dev() callbackUlf Hansson1-2/+3
The optional genpd's ->attach_dev() callback is invoked from __pm_genpd_add_device(). Let's add error handling from the response from this callback and propagate the error code. When __pm_genpd_add_device() is invoked through the generic OF-based PM domain look-up path, the device is being probed. Returning an error will mean the device won't be attached to its PM domain. Errors of -EPROBE_DEFER get special treatment and is propagated to the driver core. Therefore this change also enables the ->attach_dev() callback to be able to request for a deferred probe sequence.

2015-02-03PM / Domains: Eliminate the mutex for the generic_pm_domain_dataUlf Hansson1-23/+14
While adding devices to their PM domains, dev_pm_qos_add_notifier() was invoked while allocating the generic_pm_domain_data for the device. Since the generic_pm_domain_data's device pointer will be assigned after allocation, the ->genpd_dev_pm_qos_notifier() callback could be called prior having a valid pointer to the device. Similar scenario existed while removing a device from a genpd. To cope with these scenarios a mutex was used to protect the pointer to the device. By re-order the sequence for when dev_pm_qos_add|remove_notifier() are invoked, we make sure the ->genpd_dev_pm_qos_notifier() callback are always called with a valid device pointer available. In this way, we eliminate the need for protecting the pointer and thus we can remove the mutex from the struct generic_pm_domain_data.

Verify that there are no existing generic_pm_domain_data for the device we are about to add, since that tells us it has already been added to a genpd.

2014-12-04PM: Drop CONFIG_PM_RUNTIME from the driver coreRafael J. Wysocki7-172/+31
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. Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org> Acked-by: Kevin Hilman <khilman@linaro.org> Signed-off-by: Rafael J.
