help
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.
if CPU_IDLE
config CPU_IDLE_MULTIPLE_DRIVERS
bool "Support multiple cpuidle drivers"
default n
help
Allows the cpuidle framework to use different drivers for each CPU.
This is useful if you have a system with different CPU latencies and
states. If unsure say N.
config CPU_IDLE_GOV_LADDER
bool "Ladder governor (for periodic timer tick)"
default y

help
Select this to enable cpuidle on Calxeda processors.
