scaling_available_governors: could be "conservative ondemand userspace powersave performance", when we want to change the frequency manually, we set it to "userspace".
scaling_cur_freq
scaling_setspeed

ex: sudo sh -c 'echo 2400000 > scaling_setspeed' # set frequency to 2400000(2.4G)
ex: cat scaling_cur_freq # check if the frequency has been changed.
