+What: /sys/devices/.../power_resources_D1/
+Date: January 2013
+Contact: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+Description:
+ The /sys/devices/.../power_resources_D1/ directory is only
+ present for device objects representing ACPI device nodes that
+ use ACPI power resources for power management and support ACPI
+ power state D1.
+
+ 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 in ACPI power state D1. The names
+ of the links are the same as the names of the directories they
+ point to.
