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.
