You're right.  And that's also the same in leds-lp50xx.yaml and … well I did 
not look close enough, maybe the numbering scheme on the PCB on my desk 
confused me.

Okay, we are already talking about starting index.  What about the parent 
node's "led-controller" then in case there are more than one?  IIRC Rob 
acknowledged starting from 1 like "led-controller-1", "led-controller-2" and 
so on.

Thanks.

I'm not sure how many more iterations of this series we will need, at least 
one for the binding license acks I guess, so I could also adapt the child node 
indexes in schema and actual dts files in v8 or so.
