How to Read the CPU Core Clock Frequency from dts file

I am working with IMX8M Mini EVK Yocto Linux version.


We can read the cpu current frequency from sys interface.

For example: I want to read the CPU0

cd /sys/devices/system/cpu/cpu0/cpufreq/

cat cpuinfo_cur_freq


gives the current cpu frequency, is there any other way to find the cpu frequency apart from this.

from dts file can we read the value theoretically


Thank you, Sreedhar.
