[PATCH] dt-bindings: Cleanup standard unit properties

Rob Herring robh at kernel.org
Thu Jan 28 14:45:15 EST 2021 

Properties with standard unit suffixes already have a type and don't need
type definitions. They also default to a single entry, so 'maxItems: 1'
can be dropped.

adi,ad5758 is an oddball which defined an enum of arrays. While a valid
schema, it is simpler as a whole to only define scalar constraints.
