'-' is not valid in labels. Why do we have a whole other example just for 'resets' instead of 'reset-gpios'? That's not really worth it. Rob

I (wrongly) fixed that in the realtek.example.dtb content, which is derived from the realtek.yaml. As it has a newer mtime, it was not updated with dt_binding_check. > > Why do we have a whole other example just for 'resets' instead of > 'reset-gpios'? That's not really worth it. However, as it is not worth it, I'll drop it. > Rob
