The errors are because this schema will be applied to every 'pmic' node.

The node name here should be just 'regulators', but that should be in
the MFD schema and you should remove this level here. So the MFD would
have:

properties:
regulators:
type: object
$ref: schemas/regulator/mt6359-regulator.yaml#

And this should be at the top level of this doc.

I prefer to see a single complete example in the MFD schema rather than
piecemeal schemas in each sub schema.
