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
