Way to change imx23 cpu and ddr frequencies in linux 4.x

anatolivanov · ‎11-26-2015

HI!

I`m using buildroot to produce runnable linux image for my imx23-based board. Now i need to set cpu freq at startup of the system to 392.73MHz.

I thought that it possible to do it with "cpufreq" utility but buildroot fails to compile it for imx23. Also i need to set ddr freq to 96MHz.

So can anybody show me way how to set cpu and ddr freqs of the system or advice something else?
