[PATCH 1/2] dt-bindings: iio: temperature: ltc2983: Fix child node unevaluated properties

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The child node schemas are missing 'unevaluatedProperties' constraints,
so any unknown properties are allowed. The current structure with
multiple patternProperties schemas doesn't work for
unevaluatedProperties as each sub-schema is evaluated independently. To
fix this, move the sub-schema for all child nodes to a $defs entry and
reference it from each named child node.
