+Date: April 2013
+Contact: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+ The /sys/devices/.../power_resources_wakeup/ directory is only
+ present for device objects representing ACPI device nodes that
+ require ACPI power resources for wakeup signaling.
+ If present, it contains symbolic links to device directories
+ representing ACPI power resources that need to be turned on for
+ the given device node to be able to signal wakeup. The names of
+ the links are the same as the names of the directories they
+ point to.
