[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. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Dave Jones <davej@redhat.com>

142Description: Discover and change clock speed of CPUs
143
144 Clock scaling allows you to change the clock speed of the
145 CPUs on the fly. This is a nice method to save battery
146 power, because the lower the clock speed, the less power
147 the CPU consumes.
148
149 There are many knobs to tweak in this directory.
150
151 See files in Documentation/cpu-freq/ for more information.
152
153 In particular, read Documentation/cpu-freq/user-guide.txt
154 to learn how to control the knobs.
