289005b650SMyungJoo Ham		The /sys/class/devfreq/.../central_polling shows whether

359005b650SMyungJoo HamDescription:
369005b650SMyungJoo Ham		The /sys/class/devfreq/.../polling_interval shows and sets
379005b650SMyungJoo Ham		the requested polling interval of the corresponding devfreq
389005b650SMyungJoo Ham		object. The values are represented in ms. If the value is
399005b650SMyungJoo Ham		less than 1 jiffy, it is considered to be 0, which means
409005b650SMyungJoo Ham		no polling. This value is meaningless if the governor is
419005b650SMyungJoo Ham		not polling; thus. If the governor is not using
429005b650SMyungJoo Ham		devfreq-provided central polling
439005b650SMyungJoo Ham		(/sys/class/devfreq/.../central_polling is 0), this value
449005b650SMyungJoo Ham		may be useless.
