Hello Rob,

We found that if we write this, and the error will disapear:
 properties:
   compatible:
-    - const: mediatek,mt8195-vdo1-rdma
+    items:
+      - const: mediatek,mt8195-vdo1-rdma

But from Krzysztof's review[1], he adviced us to drop items.

Is there any suggsetion for this error or do we have any
misunderstanding?
