Adjusting NVIDIA PWM Fan Frequency to 2.4 kHz on Thor

[nagesh_accord]

@morganweng

However, we are still unable to adjust the frequency to the required value, and there does not appear to be a manual or reference guide available for this configuration.

Could you please advise how we can modify the PWM frequency to 2.4 kHz for this pin?

In addition, if we need to modify the PWM output setting or related pin configuration, could you also advise what steps, driver changes, device tree settings, or register configurations are required?

check if these links help:

Unable to set PWM to low frequency

Okay, can you share the result of rate, parent, possible_parents, period, duty_cycle and enable after you run the following commands for 810c610000.pwm? And also measure the signal from scope. As you can generate 500Hz PWM, could you generate other rate like 400Hz and 300Hz?
