+Date: April 2015
+Contact: Alexandra Yates <alexandra.yates@linux.intel.org>
+Description:
+ The /sys/power/pm_wakeup_irq file reports to user space the IRQ
+ number of the first wakeup interrupt (that is, the first
+ interrupt from an IRQ line armed for system wakeup) seen by the
+ kernel during the most recent system suspend/resume cycle.
+
+ This output is useful for system wakeup diagnostics of spurious
+ wakeup interrupts.
