[PATCH v1 0/3] Add CPUFreq support for loongson2f

[Wu Zhangjin <wuzhangjin@gmail.com>]

This patchset adds CPUFreq support for loongson2f, 'Cause loongson2f doesn't
have a fixed MIPS Timer(relative to cpu frequency), If we enable CPUFreq, the
system time will be broken.  So, an external Timer is needed, Herein, In Lemote
loongson2f family machine, there is a CS5536 MFGPT Timer, in Dexxon Gdium, it
use i8253.

This v1 revision have incorporated with the feedbacks from "Dominik Brodowski"
and Ralf. And this Thread have replied more feedbacks from Ralf:
