From 0cda8b91f2e096bbef1cb05f23c42e423eae7728 Mon Sep 17 00:00:00 2001 From: Alex Chiang <achiang@hp.com> Date: Wed, 21 Oct 2009 21:45:46 -0600 Subject: [PATCH] [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.
