4 Description:
5                 The /sys/devices/.../power_resources_wakeup/ directory is only
6                 present for device objects representing ACPI device nodes that
7                 require ACPI power resources for wakeup signaling.
9                 If present, it contains symbolic links to device directories
10                 representing ACPI power resources that need to be turned on for
11                 the given device node to be able to signal wakeup.  The names of
12                 the links are the same as the names of the directories they
13                 point to.
