| CPU idle is a generic framework for supporting software-controlled |
| idle processor power management. It includes modular cross-platform |
| governors that can be swapped during runtime. |
| |
| If you're using an ACPI-enabled platform, you should say Y here. |

| MTK governor is used for MTK SoCs to select the correct idle state, |
| which applies system scenario-based policy. |
| MTK governor is specified for MTK SoCs. |
| MTK CPUidle drivers should be paired with MTK governer. |

| help |
| MTK added many proprietary cpuidle drivers and governors. |
| And some of them set to be default for all projects. |
| But not all (MTK) projects use these driver. |
| Set this option to avoid using MTK driver / gorvernor by default. |
