1What:		/sys/class/devfreq/.../
2Date:		September 2011
3Contact:	MyungJoo Ham <[email protected]>
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.

10What:		/sys/class/devfreq/.../governor
11Date:		September 2011
12Contact:	MyungJoo Ham <[email protected]>
13Description:
14		The /sys/class/devfreq/.../governor shows the name of the
15		governor used by the corresponding devfreq object.
16
17What:		/sys/class/devfreq/.../cur_freq
18Date:		September 2011
19Contact:	MyungJoo Ham <[email protected]>
20Description:
21		The /sys/class/devfreq/.../cur_freq shows the current
22		frequency of the corresponding devfreq object. Same as
23		target_freq when get_cur_freq() is not implemented by
24		devfreq driver.
25
26What:		/sys/class/devfreq/.../target_freq
27Date:		September 2012
28Contact:	Rajagopal Venkat <[email protected]>
29Description:
30		The /sys/class/devfreq/.../target_freq shows the next governor
31		predicted target frequency of the corresponding devfreq object.
32
33What:		/sys/class/devfreq/.../polling_interval
34Date:		September 2011
35Contact:	MyungJoo Ham <[email protected]>
36Description:
37		The /sys/class/devfreq/.../polling_interval shows and sets
38		the requested polling interval of the corresponding devfreq
39		object. The values are represented in ms. If the value is
40		less than 1 jiffy, it is considered to be 0, which means
41		no polling. This value is meaningless if the governor is
42		not polling; thus. If the governor is not using
43		devfreq-provided central polling
44		(/sys/class/devfreq/.../central_polling is 0), this value
45		may be useless.
46
47What:		/sys/class/devfreq/.../userspace/set_freq
48Date:		September 2011
49Contact:	MyungJoo Ham <[email protected]>
50Description:
51		The /sys/class/devfreq/.../userspace/set_freq shows and
52		sets the requested frequency for the devfreq object if
53		userspace governor is in effect.
54
55What:		/sys/class/devfreq/.../available_frequencies
56Date:		October 2012
57Contact:	Nishanth Menon <[email protected]>
58Description:
59		The /sys/class/devfreq/.../available_frequencies shows
60		the available frequencies of the corresponding devfreq object.
61		This is a snapshot of available frequencies and not limited
62		by the min/max frequency restrictions.
