CPU Frequency change on Tegra X1

Hi everyone,

I come looking for your help because I want to change the frequency of the CPU (use the maximum frequency all the time) but I do not work on linux. Therefore I cannot use this way : https://elinux.org/Jetson/Performance

I want to write on registers but I do not find which registers I must use. I found dfllCPU_out, described on tegra210-soc-base.dtsi . It describes many information and several register address but I am not sure that is what I need.

Could you please give me tips to find which registers I should use and how to use them. Indeed, I think that I have to change voltage of the CPU too.

Thank you for your future help.
