+What:           /sys/devices/.../power_resources_D0/

+Description:
+                The /sys/devices/.../power_resources_D0/ directory is only
+                present for device objects representing ACPI device nodes that
+                use ACPI power resources for power management.
+
+                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 D0.  The names
+                of the links are the same as the names of the directories they
+                point to.
