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