How to make Rock 3A and Rock CM3 IO board pwm fan running?

Hi All

I have installed **Dedicated 3007 Cooling Fan PWM control ** on CM3 IO board.
but the fan keeps on spinning continuously.
Can somebody tells me which pwm device tree node controls this fan.

There are around 15 PWM nodes in the dtsi plz pinpoint me to the configuration
so that I could test this on my boards.

Thanks
