The recommendation is for you to use of-thermal, yes. In that way you
may benefit of describing your thermal hw specific data over DT. And you
can benefit of the existing cooling devices that have DT cooling
descriptors too, such as gpio-fan, and cpufreq-cooling, yes.

To use cpufreq-cooling, you may want to make sure your device works with
cpufreq-dt driver.

I would appreciate if you could clean up the IMX code to use the DT way
of describing thermal.
