The common clocks management code in drivers/base/power/clock_ops.c is going to be used during system-wide power transitions as well as for runtime PM, so it shouldn't depend on CONFIG_PM_RUNTIME. However, the suspend/resume functions provided by it for CONFIG_PM_RUNTIME unset, to be used during system-wide power transitions, should not behave in the same way as their counterparts defined for CONFIG_PM_RUNTIME set, because in that case the clocks are managed differently at run time. The names of the functions still contain the word "runtime" after this change, but that is going to be modified by a separate patch later. Signed-off-by: NRafael J.

There is the problem how to handle devices set up to wake up the system from sleep states during system-wide power transitions. In some cases, those devices can be turned off entirely, because the wakeup signals will be generated on their behalf anyway. In some other cases, they will generate wakeup signals if their clocks are stopped, but only if power is not removed from them. Finally, in some cases, they can only generate wakeup signals if power is not removed from them and their clocks are enabled. To allow platform-specific code to decide whether or not to put wakeup devices (and their PM domains) into low-power state during system-wide transitions, such as system suspend, introduce a new generic PM domain callback, .active_wakeup(), that will be used during the "noirq" phase of system suspend and hibernation (after image creation) to decide what to do with wakeup devices. Specifically, if this callback is present and returns "true", the generic PM domain code will not execute .stop_device() for the given wakeup device and its PM domain won't be powered off.

Make generic PM domains support system-wide power transitions (system suspend and hibernation). Add suspend, resume, freeze, thaw, poweroff and restore callbacks to be associated with struct generic_pm_domain objects and make pm_genpd_init() use them as appropriate. The new callbacks do nothing for devices belonging to power domains that were powered down at run time (before the transition). For the other devices the action carried out depends on the type of the transition. During system suspend the power domain .suspend() callback executes pm_generic_suspend() for the device, while the PM domain .suspend_noirq() callback runs pm_generic_suspend_noirq() for it, stops it and eventually removes power from the PM domain it belongs to (after all devices in the domain have been stopped and its subdomains have been powered off). During system resume the PM domain .resume_noirq() callback restores power to the PM domain (when executed for it first time), starts the device and executes pm_generic_resume_noirq() for it, while the .resume() callback executes pm_generic_resume() for the device. Finally, the .complete() callback executes pm_runtime_idle() for the device which should put it back into the suspended state if its runtime PM usage count is equal to zero at that time. The actions carried out during hibernation and resume from it are analogous to the ones described above. Signed-off-by: NRafael J. Wysocki <rjw@sisk.pl> Reviewed-by: NKevin Hilman <khilman@ti.com>

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. Signed-off-by: NRafael J.

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.

In the past we would use the GSI value to preset the ACPI SCI IRQ which worked great as GSI == IRQ: ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 low level) While that is most often seen, there are some oddities: ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 20 low level) which means that GSI 20 (or pin 20) is to be overriden for IRQ 9. Our code that presets the interrupt for ACPI SCI however would use the GSI 20 instead of IRQ 9 ending up with: xen: sci override: global_irq=20 trigger=0 polarity=1 xen: registering gsi 20 triggering 0 polarity 1 xen: --> pirq=20 -> irq=20 xen: acpi sci 20 .. snip.. calling acpi_init+0x0/0xbc @ 1 ACPI: SCI (IRQ9) allocation failed ACPI Exception: AE_NOT_ACQUIRED, Unable to install System Control Interrupt handler (20110413/evevent-119) ACPI: Unable to start the ACPI Interpreter as the ACPI interpreter made a call to 'acpi_gsi_to_irq' which got nine. It used that value to request an IRQ (request_irq) and since that was not present it failed. The fix is to recognize that for interrupts that are overriden (in our case we only care about the ACPI SCI) we should use the IRQ number to present the IRQ instead of the using GSI. End result is that we get: xen: sci override: global_irq=20 trigger=0 polarity=1 xen: registering gsi 20 triggering 0 polarity 1 xen: --> pirq=20 -> irq=9 (gsi=9) xen: acpi sci 9 which fixes the ACPI interpreter failing on startup.
