how can I increase i.MX6UL PWM clock speed?

Hi,

 

I'm working on a project where we'd like to run an i.MX6UL PWM at 1MHz.  Experiments under Linux suggest the clock feeding the PWM is only 24MHz, which gives us a max practical PWM frequency of about 400KHz.

 

Is there any way to increase the speed of the clock feeding the PWM to 100MHz?  If so, where are these clocks configured in Linux?

 

Thanks,
Cliff
