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

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.
