Hi Rob,

I also got the same two messages as BO-Chen when running
dt_binding_check [1]. 

If I remove the following items/minItems/maxItems in the mediatek,gce-
client property, the two message disappear. I don't know what's wrong
with the original syntax. Do you have any suggestions for this?

-    items:
-      items:
-        - description: phandle of GCE
-        - description: GCE subsys id
-        - description: register offset
-        - description: register size
-    minItems: 7
-    maxItems: 7
