The 1-PPS case is the "easy" one. If the PWM is adjustable on the fly, then people will use it with higher frequency signals. > I am up if this can be solved generically.

What happens today when the PWM frequency or duty cycle are changed while the signal is enabled? Do different PWM devices/drivers behave the same way? Does this series change the behavior of the am335x and friends? Thanks, Richard
