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.
