The /sys/class/devfreq/.../available_governors shows
currently available governors in the system.

+What: /sys/class/devfreq/.../min_freq
+Date: January 2013
+Contact: MyungJoo Ham <myungjoo.ham@samsung.com>
+Description:
+ The /sys/class/devfreq/.../min_freq shows and stores
+ the minimum frequency requested by users. It is 0 if
+ the user does not care. min_freq overrides the
+ frequency requested by governors.

+What: /sys/class/devfreq/.../max_freq
+Date: January 2013

+Description:
+ The /sys/class/devfreq/.../max_freq shows and stores
+ the maximum frequency requested by users. It is 0 if
+ the user does not care. max_freq overrides the
+ frequency requested by governors and min_freq.
+ The max_freq overrides min_freq because max_freq may be
+ used to throttle devices to avoid overheating.
