Changes in v5:
- formatting changes
- add unevaluatedProperties: false for nodes referencing
common schemas
- remove additionalProperties on nodes with
unevaluatedProperties: false
- add min and max to led index
Changes in v4:
- change dts example intendation from tabs
to spaces
- remove interrupt-names property
- remove obvious reg description
- split long(>80) lines
