| 8 | Select this to enable generic cpuidle driver for ARM. |
| 9 | It provides a generic idle driver whose idle states are configured |
| 10 | at run-time through DT nodes. The CPUidle suspend backend is |
| 11 | initialized by calling the CPU operations init idle hook |
| 12 | provided by architecture code. |
