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

what about reducing the voltage as well?

quoted

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

Thank you for your comments. :-)

Yes, these patches currently still in draft stage. Modify the frequency 
of 816MHz is for mac apll patch can be FROMLIST for Kylin Board,
and will work cpu frequency table as a start.

We know you want to set the appropriate frequency of different batches 
of The RK3036 SoCs take some time,so I just tested a fixed
high voltage 1.2v on my evb board, the frequency of the voltage to 
ensure that we can work needed.
We'll start work dynamically adjust the voltage.

Thanks.
