Required properties:
- compatible : should be one of
* allwinner,sun4i-a10-usb-phy
* allwinner,sun5i-a13-usb-phy
* allwinner,sun6i-a31-usb-phy
* allwinner,sun7i-a20-usb-phy
- reg : a list of offset + length pairs
- reg-names :
* "phy_ctrl"
* "pmu1"
* "pmu2" for sun4i, sun6i or sun7i
- #phy-cells : from the generic phy bindings, must be 1
- clocks : phandle + clock specifier for the phy clocks

* "usb2_reset" for sun4i, sun6i or sun7i
Example:
usbphy: phy@0x01c13400 {
#phy-cells = <1>;
compatible = "allwinner,sun4i-a10-usb-phy";
/* phy base regs, phy1 pmu reg, phy2 pmu reg */
reg = <0x01c13400 0x10 0x01c14800 0x4 0x01c1c800 0x4>;
reg-names = "phy_ctrl", "pmu1", "pmu2";
clocks = <&usb_clk 8>;
clock-names = "usb_phy";
resets = <&usb_clk 1>, <&usb_clk 2>;
reset-names = "usb1_reset", "usb2_reset";
};
