32What:		/sys/class/devfreq/.../polling_interval
33Date:		September 2011
34Contact:	MyungJoo Ham <myungjoo.ham@samsung.com>
35Description:
36		The /sys/class/devfreq/.../polling_interval shows and sets
37		the requested polling interval of the corresponding devfreq
38		object. The values are represented in ms. If the value is
39		less than 1 jiffy, it is considered to be 0, which means
40		no polling. This value is meaningless if the governor is
41		not polling; thus. If the governor is not using
42		devfreq-provided central polling
43		(/sys/class/devfreq/.../central_polling is 0), this value
44		may be useless.
