No such thing. There's a set of common properties, but that is all.
You still need to document which properties apply because it is

Ideally, the nodes should be named something we can match on like
"-pins$", but if not you can do:
additionalProperties:
type: object
$ref: pincfg-node.yaml#
properties:
bias-disable: true
...
additionalProperties: false
