You could enable pm_runtime_use_autosuspend() for pwm use, then set the timeout to the cycle length, then in the runtime_suspend make sure the enable bit is cleared if requested. But this too seems inaccurate, it would be best to clear the enable bit on some cycle completion interrupt if such thing is available. Regards, Tony
