A list of DT properties from the 'properties' section that
must always be present.
+additionalProperties / unevaluatedProperties
+ Keywords controlling how schema will validate properties not matched by this
+ schema's 'properties' or 'patternProperties'. Each schema is supposed to
+ have exactly one of these keywords in top-level part, so either
+ additionalProperties or unevaluatedProperties. Nested nodes, so properties
+ being objects, are supposed to have one as well.
+
+ * additionalProperties: false
+ Most common case, where no additional schema is referenced or if this
+ binding allows subset of properties from other referenced schemas.
+
+ * unevaluatedProperties: false
+ Used when this binding references other schema whose all properties
+ should be allowed.
+
+ * additionalProperties: true
+ Rare case, used for schemas implementing common set of properties. Such
+ schemas are supposed to be referenced by other schemas, which then use
+ 'unevaluatedProperties: false'. Typically bus or common-part schemas.

Optional. A list of one or more DTS hunks implementing the
binding. Note: YAML doesn't allow leading tabs, so spaces must be used instead.
Add to the list of schema contents expected keywords with their explanation: additionalProperties and unevaluatedProperties. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> --- .../devicetree/bindings/writing-schema.rst | 20 +++++++++++++++++++ 1 file changed, 20 insertions(+)
