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