4 Description:
5                 The /sys/devices/.../power_resources_D2/ directory is only
6                 present for device objects representing ACPI device nodes that
7                 use ACPI power resources for power management and support ACPI
8                 power state D2.
10                 If present, it contains symbolic links to device directories
11                 representing ACPI power resources that need to be turned on for
12                 the given device node to be in ACPI power state D2.  The names
13                 of the links are the same as the names of the directories they
14                 point to.
