| 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. | |
| 9 | ||
| 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. |
