- 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.
