Hi Krzysztof,

Thanks for your comments and time spent on reviewing my patch.
All of those improvements will be included in next version. 
Also, I would like to know your opinion about one. 

quoted

+  marvell,system-controller:

+    description: a phandle to the system controller.

+patternProperties:

The name should be "(ethernet-)?port", unless anything depends on
particular naming?

What do you think about pattern "^(ethernet-)?eth[0-9a-f]+(@.*)?$"?
It resembles pattern found in net/ethernet-phy.yaml like
properties:$nodename:pattern:"^ethernet-phy(@[a-f0-9]+)?$", while 
still passing `dt_binding_check' and `dtbs_check'. It should also 
comply with your comment.

Best regards,
Michał
