| 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. | ||
