prompt "CPU idle drivers for ARM64"
default NO_CPUIDLE_DRIVER

bool "Generic ARM64 CPU idle Driver"
select ARM64_CPU_SUSPEND
select DT_IDLE_STATES
help
Select this to enable generic cpuidle driver for ARM64.
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 ARM64_CPUIDLE_SPRD
bool "Spreadtrum ARM64 CPU idle Driver"
select DT_IDLE_STATES
help
Select this to enable spreadtrum cpuidle driver for ARM v8.
It provides a spreadtrum idle driver whose idle states are configured
at run-time through DT nodes. The CPUidle suspend backend is
initialized by the device tree parsing code on matching the entry
method to the respective CPU operations.
config NO_CPUIDLE_DRIVER
bool "NO CPUIDLE DRIVER"
help
If the curren system is arm32, we have to select this config.This config
has not load any arm64 idle drivers.But cpu can also enter WFI.
