1	Allwinner A80 USB Clock Control Binding
2	---------------------------------------
3	
4	Required properties :
5	- compatible: must contain one of the following compatibles:
6			- "allwinner,sun9i-a80-usb-clocks"
7	
8	- reg: Must contain the registers base address and length
9	- clocks: phandle to the clocks feeding the USB subsystem. Two are needed:
10	  - "bus": the bus clock for the whole USB subsystem
11	  - "hosc": the high frequency oscillator (usually at 24MHz)
12	- clock-names: Must contain the clock names described just above
13	- #clock-cells : must contain 1
14	- #reset-cells : must contain 1
15	
16	Example:
17	usb_clocks: clock@a08000 {
18		compatible = "allwinner,sun9i-a80-usb-clks";
19		reg = <0x00a08000 0x8>;
20		clocks = <&ccu CLK_BUS_USB>, <&osc24M>;
21		clock-names = "bus", "hosc";
22		#clock-cells = <1>;
23		#reset-cells = <1>;
24	};
