Hi Rob and krzysztof,
I got the two messages when running dt_binding_check [1]. This binding
patch was sent previously in [2].
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
