Overclocking i.MX6 DualLite from 792 MHz to 1 GHz

I am using an i.MX6 DualLite Sabre SD board here. It runs with a kernel configuration that limits the max CPU frequency to 792 MHz.

From what I saw, NXP rated the DualLite to a maximum frequency of 1.2 GHz.

Is it then possible to raise the CPU frequency on my Sabre SD board to 1 GHz? This should be within the stable range, shouldn't it? If so, what do I have to configure / patch to get 1 GHz?

Hi Carlos

 

>Is it then possible to raise the CPU frequency on my Sabre SD board to 1 GHz? 

 

it is supported in nxp linux releases, one can look at dts file:

https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm/boot/dts/imx6dl.dtsi?h=lf-5.10.y
cpu0: cpu@0 {
operating-points = <
/* kHz uV */
996000 1250000..

Usage can be found in AN4576 sect.5.4.3  how to set cpu frequency 

i.MX 6DualLite Power Consumption Measurement

and sect.2.5.3 CPU Frequency Scaling (CPUFREQ)   i.MX Linux Reference Manual​
