From 9726b43a4d7aaa5b30f559e78768aeb3d17bc224 Mon Sep 17 00:00:00 2001 From: Wu Zhangjin Date: Tue, 17 Nov 2009 01:32:58 +0800 Subject: MIPS: Add basic CPUFreq options. This patch adds basic options for MIPS CPUFreq support. Since the cp0 timer's frequency is based on the processor clockrate it can not be used with CPUFReq; an additional external timer is required.
