9 Select this to enable generic cpuidle driver for ARM.
10 It provides a generic idle driver whose idle states are configured
11 at run-time through DT nodes. The CPUidle suspend backend is
12 initialized by calling the CPU operations init idle hook
13 provided by architecture code.

23 Select this option to enable CPU idle driver for big.LITTLE based
24 ARM systems. Driver manages CPUs coordination through MCPM and
25 define different C-states for little and big cores through the
26 multiple CPU idle drivers infrastructure.
