[PATCH] dt-bindings: leds: Add missing (unevaluated|additional)Properties on child nodes

[PATCH] dt-bindings: leds: Add missing (unevaluated|additional)Properties on child nodes

[Rob Herring]

In order to ensure only documented properties are present, node schemas
must have unevaluatedProperties or additionalProperties set to false
(typically).

Patch does way more than that:

Can we get some explanation why that's correct?

Best regards,

It only 'ensure only documented properties are present', but yeah, it
is sometimes more than just adding unevaluatedProperties.

> Can we get some explanation why that's correct?

...adds missing $ref if needed, and fixes resulting errors about
unevaluatedProperties.

BTW, these are just the simple ones. The led bindings with multi-led
nodes are more of a mess. I haven't decided exactly how to fix those.
