23  * @name: Name of the wakeup source
24  * @id: Wakeup source id
25  * @entry: Wakeup source list entry
26  * @lock: Wakeup source lock
28  * @timer: Wakeup timer list
29  * @timer_expires: Wakeup timer expiration
30  * @total_time: Total time this wakeup source has been active.
31  * @max_time: Maximum time this wakeup source has been continuously active.
32  * @last_time: Monotonic clock when the wakeup source's was touched last time.
34  * @event_count: Number of signaled wakeup events.
35  * @active_count: Number of times the wakeup source was activated.
36  * @relax_count: Number of times the wakeup source was deactivated.
37  * @expire_count: Number of times the wakeup source's timeout has expired.

223  * device_init_wakeup - Device wakeup initialization.
225  * @enable: Whether or not to enable @dev as a wakeup device.
227  * By default, most devices should leave wakeup disabled.  The exceptions are
228  * devices that everyone expects to be wakeup sources: keyboards, power buttons,
230  * own wakeup requests but merely forward requests from one bus to another
231  * (like PCI bridges) should have wakeup enabled by default.
