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)". > > + > > + '#size-cells': > > + description: Number of size cells on the MDIO bus. > > + const: 0 Also I'll drop this. > > + ports: > > + type: object > > I think ethernet-ports is the preferred name.

You can have a 0 port switch? Thank you for pointed it out. I'll add "ethernet-ports" and drop '#address-cells' and '#size-cells'. Best regards, Yoshihiro Shimoda > Andrew
