10:47 <ukleinek> heyho, I have no access to hardware docs (yet), could please someone lookup the duty and period length for a PWM on the mt8365 (or a similar SoC) for given values of clock freq, CLKDIV, PWMDWIDTH and PWMTHRES? I would expect something like duty = ((PWMTHRES + 1) << CLKDIV) / freq and period = ((PWMDWIDTH + 1) << CLKDIV) / freq). Can someone confirm please?

10:50 <ukleinek> In the PWM driver's .apply callback the "+ 1" isn't implemented, but I see the output toggling when I set PWMTHRES = 0

10:52 <ukleinek> so the formula above is what I think is the right one after a bit of playing around with the hardware feeding an FX2/sigrok.
