dt-bindings: Cleanup standard unit properties

2021-01-29T22:36:06+00:00

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.

reported:

dt-bindings: Fix JSON pointers

2020-12-18T21:14:44+00:00

The correct syntax for JSON pointers begins with a '/' after the '#'.
Without a '/', the string should be interpreted as a subschema
identifier. The jsonschema module currently doesn't handle subschema
identifiers and incorrectly allows JSON pointers to begin without a '/'.
Let's fix this before it becomes a problem when jsonschema module is
fixed.

dt-bindings: More whitespace clean-ups in schema files

2020-10-26T21:13:56+00:00

Clean-up incorrect indentation, extra spaces, and missing EOF newline in
schema files. Most of the clean-ups are for list indentation which
should always be 2 spaces more than the preceding keyword.

Found with yamllint (now integrated into the checks).
