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