Thinking again. Why additionalProperties? unevaluatedProperties
looks more reasonable for me. There are additional properties but
they should be evaluated by another schema.

and then it just accepts anything with compatible twl6032-charger e.g.
and does not care about anything in patch 2, because it has a different
compatible.

Or a ti,twl4030.yaml and a ti,twl603X.yaml. 6030 and 6032 have more in
common than the 4030.
I would propose that is something for the next more final cleaning
up/conversion round. First I would like to avoid having drained
batteries because of no charging, so allow for more automated testing
and bisecting. 
I think I will prepare a v2 series on monday.
