This doesn't yet do anything in the tools, but make it explicit so we can check either 'unevaluatedProperties' or 'additionalProperties' is present in schemas. 'unevaluatedProperties' is appropriate when including another schema (via '$ref') and all possible properties and/or child nodes are not explicitly listed in the schema with the '$ref'. This is in preparation to add a meta-schema to check for missing 'unevaluatedProperties' or 'additionalProperties'. This has been a constant source of review issues.

title: STMicroelectronics STM32 Voltage reference buffer bindings
|
|
|
|
description: |
|
|
Some STM32 devices embed a voltage reference buffer which can be used as
|
|
voltage reference for ADCs, DACs and also as voltage reference for external
|
|
components through the dedicated VREF+ pin.
