1	Allwinner sun9i USB PHY
2	-----------------------
3	
4	Required properties:
5	- compatible : should be one of
6	  * allwinner,sun9i-a80-usb-phy
7	- reg : a list of offset + length pairs
8	- #phy-cells : from the generic phy bindings, must be 0
9	- phy_type : "hsic" for HSIC usage;
10		     other values or absence of this property indicates normal USB
11	- clocks : phandle + clock specifier for the phy clocks
12	- clock-names : depending on the "phy_type" property,
13	  * "phy" for normal USB
14	  * "hsic_480M", "hsic_12M" for HSIC
15	- resets : a list of phandle + reset specifier pairs
16	- reset-names : depending on the "phy_type" property,
17	  * "phy" for normal USB
18	  * "hsic" for HSIC
19	
20	Optional Properties:
21	- phy-supply : from the generic phy bindings, a phandle to a regulator that
22		       provides power to VBUS.
23	
24	It is recommended to list all clocks and resets available.
25	The driver will only use those matching the phy_type.
26	
27	Example:
28		usbphy1: phy@a01800 {
29			compatible = "allwinner,sun9i-a80-usb-phy";
30			reg = <0x00a01800 0x4>;
31			clocks = <&usb_phy_clk 2>, <&usb_phy_clk 10>,
32			       <&usb_phy_clk 3>;
33			clock-names = "hsic_480M", "hsic_12M", "phy";
34			resets = <&usb_phy_clk 18>, <&usb_phy_clk 19>;
35			reset-names = "hsic", "phy";
36			#phy-cells = <0>;
37		};
