+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.
