The pulse width/frequency modulation peripheral supports generating a repeating pulse. It is useful for controlling LCD brightness.
Surely this should be modeled as a driver that's instantiated from DT, which provides n PWMs. As such, I'd expect the driver to have some kind of init/probe function, and:
+void pwfm_enable(struct pwfm_ctlr *pwfm, int rate, int pulse_width,
int freq_divider);
to take a pwm_id parameter too.
