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