6 bool "Generic ARM/ARM64 CPU idle Driver"
8 select CPU_IDLE_MULTIPLE_DRIVERS
10 Select this to enable generic cpuidle driver for ARM.
11 It provides a generic idle driver whose idle states are configured
12 at run-time through DT nodes. The CPUidle suspend backend is
13 initialized by calling the CPU operations init idle hook
14 provided by architecture code.

18 depends on ARM_PSCI_FW
20 select CPU_IDLE_MULTIPLE_DRIVERS
22 Select this to enable PSCI firmware based CPUidle driver for ARM.
23 It provides an idle driver that is capable of detecting and
24 managing idle states through the PSCI firmware interface.
