	  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.

        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

config CPU_IDLE_GOV_MENU
	bool "Menu governor (for tickless system)"
	default y

	select ARM_CPU_SUSPEND
	help
	  Select this to enable cpuidle on Calxeda processors.

	bool "CPU Idle Driver for Xilinx Zynq processors"
	depends on ARCH_ZYNQ
	help
	  Select this to enable cpuidle on Xilinx Zynq processors.
