Yes, I have one for this device. And Han Gao told me that he will send
the board patch for the evb board. So I only send the driver.
And the fragment for the evb board is likes below, I think it is kind
of trivial:

&gmac0 {
phy-handle = <&phy0>;
phy-mode = "rgmii-txid";
status = "okay";

mdio {
phy0: phy@0 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <0>;
reset-gpios = <&port0a 27 GPIO_ACTIVE_LOW>;
reset-assert-us = <100000>;
reset-deassert-us = <100000>;
};
};
};
