Rafael J. Wysocki 41a2a4665d ACPI / PM: Expose lists of device wakeup power resources to user space 
Commit 18a3870 (ACPI / PM: Expose lists of device power resources
to user space) exposed the lists of ACPI power resources associated
with power states of ACPI devices, but it didn't expose the lists
of ACPI wakeup power resources, which also is necessary to get the
full picture of dependencies between ACPI devices and power
resources.

For this reason, for every ACPI device node having a list of ACPI
wakeup power resources associated with it, expose that list to user
space in analogy with commit 18a3870.

What: /sys/devices/.../power_resources_wakeup/ Date: April 2013 Contact: Rafael J. Wysocki rafael.j.wysocki@intel.com Description: 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.
