Actually, we need more cpu freqs which are 50MHz integer multiples.

what about reducing the voltage as well?
From rk3288-specific discussions I remember that reducing the frequency
without touching the voltage, didn't really save so much energy. And it looks like it was running 816MHz at 1.0V just fine as well. I guess you should find out which voltages are really necessary for each step. Heiko
