| 7 | use ACPI power resources for power management and support ACPI |
| 8 | power state D2. |

| 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 |
