   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.
