5Required properties:
6 - compatible: should be
7		"ti,keystone-dwc3" for Keystone 2 SoCs
8		"ti,am654-dwc3" for AM654 SoC
9 - #address-cells, #size-cells : should be '1' if the device has sub-nodes
10   with 'reg' property.
11 - reg : Address and length of the register set for the USB subsystem on
12   the SOC.
13 - interrupts : The irq number of this device that is used to interrupt the
14   MPU.
15 - ranges: allows valid 1:1 translation between child's address space and
16   parent's address space.

18SoC-specific Required Properties:
19The following are mandatory properties for Keystone 2 66AK2HK, 66AK2L and 66AK2E
20SoCs only:
21
22- clocks:		Clock ID for USB functional clock.
23- clock-names:		Must be "usb".
24
25
26The following are mandatory properties for 66AK2G and AM654:
27
28- power-domains:	Should contain a phandle to a PM domain provider node
29			and an args specifier containing the USB device id
30			value. This property is as per the binding,
31			Documentation/devicetree/bindings/soc/ti/sci-pm-domain.txt
32
33Sub-nodes:
34The dwc3 core should be added as subnode to Keystone DWC3 glue.
35- dwc3 :
36   The binding details of dwc3 can be found in:
37   Documentation/devicetree/bindings/usb/dwc3.txt

39Example:
40	usb: usb@2680000 {
41		compatible = "ti,keystone-dwc3";
42		#address-cells = <1>;
43		#size-cells = <1>;
44		reg = <0x2680000 0x10000>;
45		clocks = <&clkusb>;
46		clock-names = "usb";
47		interrupts = <GIC_SPI 393 IRQ_TYPE_EDGE_RISING>;
48		ranges;
49
50		dwc3@2690000 {
51			compatible = "synopsys,dwc3";
52			reg = <0x2690000 0x70000>;
53			interrupts = <GIC_SPI 393 IRQ_TYPE_EDGE_RISING>;
54			usb-phy = <&usb_phy>, <&usb_phy>;
55		};
