| 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. | |

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