Subject[PATCH v2] dt-bindings: chrome: google,cros-ec-typec: restrict allowed properties
Date
Describe exactly what properties are allowed in Google Chrome OS EC Type
C port, so the schema can properly validate the DTS. Existing DTS
defines always connectors with unit addresses, not a sole "connector"
child.
