NAME
       __pci_enable_wake - enable PCI device as wakeup event source

SYNOPSIS
       int __pci_enable_wake(struct pci_dev * dev, pci_power_t state, bool runtime, bool enable);

ARGUMENTS
       dev
	   PCI device affected

       state
	   PCI state from which device will issue wakeup events

       runtime
	   True if the events are to be generated at run time

       enable
	   True to enable event generation; false to disable

DESCRIPTION
       This enables the device as a wakeup event source, or disables it. When such events involves platform-specific hooks, those hooks are called
       automatically by this routine.

       Devices with legacy power management (no standard PCI PM capabilities) always require such platform hooks.

RETURN VALUE
       0 is returned on success -EINVAL is returned if device is not supposed to wake up the system Error code depending on the platform is
       returned if both the platform and the native mechanism fail to enable the generation of wake-up events
