The power domains are a property of / implemented in the PMU. As such,
they should be modelled as child nodes of the PMU.

Note: Ideally, the newly added properties (ranges, etc.) should only be
'required' if "^power-domain@[0-9a-f]+$" exists as a patternProperty,
as they're needed only in that case. As-is, this patch now causes
warnings for existing DTs as they don't specify the new properties (and
they shouldn't need to). Only if DTs are updated to include
power-domains, such an update should also add the new properties.
I've not been able to come up with the correct schema syntax to achieve
that. dependencies, dependentRequired, and dependentSchemas don't seem
to support patterns. Similarly,
- if:
required:
- ...
then:
required:
- ...
doesn't allow patterns in the 'if' block (or I didn't get the syntax
right).This is a known limitation in json-schema. Not sure if they've come up with a solution yet. Rob
