+Description:
+                The /sys/power/pm_async file controls the switch allowing the
+                user space to enable or disable asynchronous suspend and resume
+                of devices.  If enabled, this feature will cause some device
+                drivers' suspend and resume callbacks to be executed in parallel
+                with each other and with the main suspend thread.  It is enabled
+                if this file contains "1", which is the default.  It may be
+                disabled by writing "0" to this file, in which case all devices
+                will be suspended and resumed synchronously.

+Description:
+                The /sys/power/wakeup_count file allows user space to put the
+                system into a sleep state while taking into account the
+                concurrent arrival of wakeup events.  Reading from it returns
+                the current number of registered wakeup events and it blocks if
+                some wakeup events are being processed at the time the file is
+                read from.  Writing to it will only succeed if the current
+                number of wakeup events is equal to the written value and, if
+                successful, will make the kernel abort a subsequent transition
+                to a sleep state if any wakeup events are reported after the
+                write has returned.
