Perhaps add a default phy mode, like on other SoCs?

    phy-mode = "rgmii"';

Also missing:

    #address-cells = <1>;
    #size-cells = <0>;

Same comments for eth1.

I skipped this (even it was available on the other SoCs) as I consider the
phy-mode is board specific.

Same for these.

IC.  Still, it's good to have some consistency across boards.

These are required, and always have the same values, so it makes more
sense to have them in the SoC .dtsi file, once.

I remember I had a compilation warning with an Ethernet controller
configured with fixed-link having #address-cells, #size-cells. With
fixed-link these were not needed.

Anyway... I'll keep all in dtsi if you prefer it this way.

I think EtherAVB always use MDIO for management, so fixed-link is
not applicable.
