          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.

	  Select this option to enable CPU idle driver for big.LITTLE based
	  ARM systems. Driver manages CPUs coordination through MCPM and
	  define different C-states for little and big cores through the
	  multiple CPU idle drivers infrastructure.
