| Description: | |
| The /sys/devices/.../power_resources_D2/ directory is only | |
| present for device objects representing ACPI device nodes that | |
| use ACPI power resources for power management and support ACPI | |
| power state D2. | |
| 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 D2. The names | |
| of the links are the same as the names of the directories they | |
| point to. |
