30  *	wakeup - Report/change current wakeup option for device
32  *	Some devices support "wakeup" events, which are hardware signals
34  *	devices have one of three values for the sysfs power/wakeup file:
38  *	 + "\n" for temporary or permanent inability to issue wakeup.
42  *	Familiar examples of devices that can issue wakeup events include
47  *	Some wakeup events use normal IRQ lines; other use special out
51  *	wakeup signaling as part of changing device power states, respecting
54  *	Devices may not be able to generate wakeup events from all power
57  *	active, or which may have wakeup disabled.  Some drivers rely on
58  *	wakeup events internally (unless they are disabled), keeping
92  *	wakeup_count - Report the number of wakeup events related to the device
