PWM overlay broken?

[OttawaHacker]

I've setup the pwm overlay but while it shows up the pwm devices in /devices - it is missing the pwm0 control

I've read couple posts where ppl have been able to override the overlays by decompiling the original one, but I can't make sense of the dtc dtb dtbo and dtsi files 😕 

Any guides or other suggestions to fix the pwm control?

If anyone else is having the same issue, the overlays are just fine - the pwm0 control only shows up after you do

echo 0 > ${PWM}/pwm/pwmchip*/export
