Hi Krzysztof,

Makes sense. I'll take a look at hi3660-hikey960.dts itself since it
also has the port@0 required property warning on the same node. Will
send a separate patch.

Dropping patch 2/2 from this series.

Can patch 1/2 (.txt removal) be applied independently with your Reviewed-by?

Thanks,
