4Description:
5		Provide a place in sysfs for the devfreq objects.
6		This allows accessing various devfreq specific variables.
7		The name of devfreq object denoted as ... is same as the
8		name of device using devfreq.

13Description:
14		The /sys/class/devfreq/.../governor shows the name of the
15		governor used by the corresponding devfreq object.

20Description:
21		The /sys/class/devfreq/.../cur_freq shows the current
22		frequency of the corresponding devfreq object.

24What:		/sys/class/devfreq/.../polling_interval
25Date:		September 2011
26Contact:	MyungJoo Ham <[email protected]>
27Description:
28		The /sys/class/devfreq/.../polling_interval shows and sets
29		the requested polling interval of the corresponding devfreq
30		object. The values are represented in ms. If the value is
31		less than 1 jiffy, it is considered to be 0, which means
32		no polling. This value is meaningless if the governor is
33		not polling; thus. If the governor is not using
34		devfreq-provided central polling
35		(/sys/class/devfreq/.../central_polling is 0), this value
36		may be useless.

38What:		/sys/class/devfreq/.../userspace/set_freq
39Date:		September 2011

41Description:
42		The /sys/class/devfreq/.../userspace/set_freq shows and
43		sets the requested frequency for the devfreq object if
44		userspace governor is in effect.
