My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

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?
