      PCI ACPI: Rework PCI handling of wake-up · eb9d0fe4
      Rafael J. Wysocki authored
      * Introduce function acpi_pm_device_sleep_wake() for enabling and
        disabling the system wake-up capability of devices that are power
        manageable by ACPI.
      
      * Introduce function acpi_bus_can_wakeup() allowing other (dependent)
        subsystems to check if ACPI is able to enable the system wake-up
        capability of given device.
      
      * Introduce callback .sleep_wake() in struct pci_platform_pm_ops and
        for the ACPI PCI 'driver' make it use acpi_pm_device_sleep_wake().
      
      * Introduce callback .can_wakeup() in struct pci_platform_pm_ops and
        for the ACPI 'driver' make it use acpi_bus_can_wakeup().
      
      * Move the PME# handlig code out of pci_enable_wake() and split it
        into two functions, pci_pme_capable() and pci_pme_active(),
        allowing the caller to check if given device is capable of
        generating PME# from given power state and to enable/disable the
        device's PME# functionality, respectively.
      
      * Modify pci_enable_wake() to use the new ACPI callbacks and the new
        PME#-related functions.
      
      * Drop the generic .platform_enable_wakeup() callback that is not
        used any more.
      
      * Introduce device_set_wakeup_capable() that will set the
        power.can_wakeup flag of given device.
      
      * Rework PCI device PM initialization so that, if given device is
        capable of generating wake-up events, either natively through the
        PME# mechanism, or with the help of the platform, its
        power.can_wakeup flag is set and its power.should_wakeup flag is
        unset as appropriate.
      
      * Make ACPI set the power.can_wakeup flag for devices found to be
        wake-up capable by it.
      
      * Make the ACPI wake-up code enable/disable GPEs for devices that
        have the wakeup.flags.prepared flag set (which means that their
        wake-up power has been enabled).
