config ARM_CPUIDLE
bool "Generic ARM/ARM64 CPU idle Driver"
select DT_IDLE_STATES
select CPU_IDLE_MULTIPLE_DRIVERS
help
Select this to enable generic cpuidle driver for ARM.
It provides a generic idle driver whose idle states are configured
at run-time through DT nodes. The CPUidle suspend backend is
initialized by calling the CPU operations init idle hook
provided by architecture code.
config ARM_BIG_LITTLE_CPUIDLE
bool "Support for ARM big.LITTLE processors"
depends on ARCH_VEXPRESS_TC2_PM || ARCH_EXYNOS
depends on MCPM && !ARM64
select ARM_CPU_SUSPEND
select CPU_IDLE_MULTIPLE_DRIVERS
select DT_IDLE_STATES
help
Select this option to enable CPU idle driver for big.LITTLE based
ARM systems. Driver manages CPUs coordination through MCPM and
define different C-states for little and big cores through the
multiple CPU idle drivers infrastructure.
config ARM_CLPS711X_CPUIDLE
bool "CPU Idle Driver for CLPS711X processors"
depends on ARCH_CLPS711X && !ARM64 || COMPILE_TEST
help
Select this to enable cpuidle on Cirrus Logic CLPS711X SOCs.
config ARM_HIGHBANK_CPUIDLE
bool "CPU Idle Driver for Calxeda processors"
depends on ARM_PSCI && !ARM64
select ARM_CPU_SUSPEND
help
Select this to enable cpuidle on Calxeda processors.
config ARM_KIRKWOOD_CPUIDLE
bool "CPU Idle Driver for Marvell Kirkwood SoCs"
depends on MACH_KIRKWOOD && !ARM64
help
This adds the CPU Idle driver for Marvell Kirkwood SoCs.
config ARM_ZYNQ_CPUIDLE
bool "CPU Idle Driver for Xilinx Zynq processors"
depends on ARCH_ZYNQ && !ARM64
help
Select this to enable cpuidle on Xilinx Zynq processors.
config ARM_U8500_CPUIDLE
bool "Cpu Idle Driver for the ST-E u8500 processors"
depends on ARCH_U8500 && !ARM64
help
Select this to enable cpuidle for ST-E u8500 processors
config ARM_AT91_CPUIDLE
bool "Cpu Idle Driver for the AT91 processors"
default y
depends on ARCH_AT91 && !ARM64
help
Select this to enable cpuidle for AT91 processors
config ARM_EXYNOS_CPUIDLE
bool "Cpu Idle Driver for the Exynos processors"
depends on ARCH_EXYNOS && !ARM64
select ARCH_NEEDS_CPU_IDLE_COUPLED if SMP
help
Select this to enable cpuidle for Exynos processors
config ARM64_EXYNOS_CPUIDLE
bool "Exynos ARM64 CPU idle Driver"
depends on ARCH_EXYNOS && ARM64
select CPU_IDLE_MULTIPLE_DRIVERS
select DT_IDLE_STATES
help
Select this to enable cpuidle for ARM64 Exynos processors.
config ARM_MVEBU_V7_CPUIDLE
bool "CPU Idle Driver for mvebu v7 family processors"
depends on ARCH_MVEBU && !ARM64
help
Select this to enable cpuidle on Armada 370, 38x and XP processors.
