+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.

+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.
