Oh wow, thanks for rustifying PWM. That might be my chance to actually
learn Rust.

I don't know when I will find the time to look into that in detail but
one thing I'd like to have for Rust support is that the drivers use the
new abstraction (i.e. .round_waveform_tohw() + .round_waveform_fromhw()
+ .read_waveform() + .write_waveform()) instead of the older .apply()
callback.

Best regards
Uwe
