[CPUFREQ] Documentation: ABI: /sys/devices/system/cpu/cpu#/cpufreq/ 



This is a complex interface and is already described in
Documentation/cpu-freq/, especially in the user-guide.txt file.

No need to copy/paste all that information. Let's just alert the reader
to the presence of the user-guide.

Description:	Discover and change clock speed of CPUs



		Clock scaling allows you to change the clock speed of the

		CPUs on the fly. This is a nice method to save battery

		power, because the lower the clock speed, the less power

		the CPU consumes.



		There are many knobs to tweak in this directory.



		See files in Documentation/cpu-freq/ for more information.



		In particular, read Documentation/cpu-freq/user-guide.txt

		to learn how to control the knobs.
