Please could you explain this a bit more.

I think ethernet-ports is the preferred name.

So ports are not required? You can have a 0 port switch?

Hi Andrew,

Thank you for your review!

I realized that the property is completely wrong.
This #address-cells here (out of "port") is not needed.
So, I'll drop it.
Instead of that, I'll add a description of "#address-cell"
in the port as " Port number of ETHA (TSNA)".

Also I'll drop this.

OK. I'll rename it.

Thank you for pointed it out. I'll add "ethernet-ports" and
drop '#address-cells' and '#size-cells'.

Best regards,

Is serdes really the same h/w block? Based on addresses, doesn't seem 
like it.

It's better if you put MDIO under an 'mdio' node. That also needs a ref 
to mdio.yaml.

You're correct. The serdes is not the same h/w block. I'll fix it somehow.
