Sorry if this is redundant: I wonder if it'd make sense to prefix the property like this: "raspberrypi,wifi-2.4ghz-coexistence." I tend to associate the lack of pref= ix with generic properties, and also thought it was a rule. Although I may hav= e as well imagined it. Other than that the series looks OK to me.
