[PATCH v2 3/3] dt-bindings: serial: restrict possible child node names

From: Krzysztof Kozlowski
Date: Fri Jan 27 2023 - 04:33:02 EST


The re-usable serial.yaml schema matches every property with ".*"
pattern, thus any other schema referencing it will not report unknown
(unevaluated) properties. This hides several wrong properties. It is
a limitation of dtschema, thus provide a simple workaround: expect
children to be only of few names matching upstream usage (Bluetooth,
GNSS, GPS and MCU).
