   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.
