Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.

There were changes in v11, I thought you'd want to review again?

Anyway, I can resend a v12 with all the Rb/Ab if that works better for you.

Looked like a minor change from the changelog, so it would have been
appropriate to keep. However, I see another issue.

This won't work because the top level schema restricts this to 1. The
top level needs to say:

power-domains:
  minItems: 1
  maxItems: 3

And you need just 'minItems: 3' here and 'maxItems: 1' in the else clause.

And drop the description. That's every 'power-domains' property.
