| 9 | Select this to enable generic cpuidle driver for ARM. | |
| 10 | It provides a generic idle driver whose idle states are configured | |
| 11 | at run-time through DT nodes. The CPUidle suspend backend is | |
| 12 | initialized by calling the CPU operations init idle hook | |
| 13 | provided by architecture code. | |

22 | help |
| 23 | Select this option to enable CPU idle driver for big.LITTLE based | |
| 24 | ARM systems. Driver manages CPUs coordination through MCPM and | |
| 25 | define different C-states for little and big cores through the | |
| 26 | multiple CPU idle drivers infrastructure. | |
