This is what I tried:

--- a/Documentation/devicetree/bindings/trivial-devices.yaml
+++ b/Documentation/devicetree/bindings/trivial-devices.yaml
@@ -424,6 +424,9 @@ required:
   - compatible
   - reg

-additionalProperties: false
+allOf:
+  - $ref: /schemas/spi/spi-peripheral-props.yaml#
+
+unevaluatedProperties: false

but still get:

$ make CHECK_DTBS=y rockchip/rv1108-elgin-r1.dtb
  SCHEMA  Documentation/devicetree/bindings/processed-schema.json

'spi-cpol' were unexpected)

Any suggestions?
