-enable_wake
------------
-
-Usage:
-
-if (dev->driver && dev->driver->enable_wake)
- dev->driver->enable_wake(dev,state,enable);
-
-This callback is generally only relevant for devices that support the PCI PM
-spec and have the ability to generate a PME# (Power Management Event Signal)
-to wake the system up. (However, it is possible that a device may support
-some non-standard way of generating a wake event on sleep.)
-
-Bits 15:11 of the PMC (Power Mgmt Capabilities) Register in a device's
-PM Capabilities describe what power states the device supports generating a
-wake event from:
-
-+------------------+
-| Bit | State |
-+------------------+
-| 11 | D0 |
-| 12 | D1 |
-| 13 | D2 |
-| 14 | D3hot |
-| 15 | D3cold |
-+------------------+
-
-A device can use this to enable wake events:
-
- pci_enable_wake(dev,state,enable);
-
-Note that to enable PME# from D3cold, a value of 4 should be passed to
-pci_enable_wake (since it uses an index into a bitmask). If a driver gets
-a request to enable wake events from D3, two calls should be made to
-pci_enable_wake (one for both D3hot and D3cold).
