the nodes in the dts are ordered by address, please move it accordingly. I 
guess a good position might be to have the "phy" before the "pinctrl" node.

Also please reorder the properties a bit to have the "compatible" at the top 
of the list, like

		compatible = "rockchip,rk3288-usb-phy";
		rockchip,grf = <&grf>;
		#phy-cells = <1>;
		#address-cells = <1>;
		#size-cells = <0>;
		status = "disabled";

		subnodes...


Thanks
Heiko
