Hello Krzysztof,
I review https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/example-schema.yaml?h=v7.0-rc1
I will do following modify
-    enum:
-      - aspeed,ast2400-sd-controller
-      - aspeed,ast2500-sd-controller
-      - aspeed,ast2600-sd-controller
+    oneOf:
+      - items:
+          - enum:
+              - aspeed,ast2400-sd-controller
+              - aspeed,ast2500-sd-controller
+              - aspeed,ast2600-sd-controller
+      - items:
+          - const: aspeed,ast2700-sd-controller
+          - const: aspeed,ast2600-sd-controller
+
Thanks the review.
