1TI Keystone Soc USB Controller
2
3DWC3 GLUE
4
5Required properties:
6 - compatible: should be "ti,keystone-dwc3".
7 - #address-cells, #size-cells : should be '1' if the device has sub-nodes
8   with 'reg' property.
9 - reg : Address and length of the register set for the USB subsystem on
10   the SOC.
11 - interrupts : The irq number of this device that is used to interrupt the
12   MPU.
13 - ranges: allows valid 1:1 translation between child's address space and
14   parent's address space.
15 - clocks: Clock IDs array as required by the controller.
16 - clock-names: names of clocks correseponding to IDs in the clock property.

18Sub-nodes:
19The dwc3 core should be added as subnode to Keystone DWC3 glue.
20- dwc3 :
21   The binding details of dwc3 can be found in:
22   Documentation/devicetree/bindings/usb/dwc3.txt

24Example:
25	usb: usb@2680000 {
26		compatible = "ti,keystone-dwc3";
27		#address-cells = <1>;
28		#size-cells = <1>;
29		reg = <0x2680000 0x10000>;
30		clocks = <&clkusb>;
31		clock-names = "usb";
32		interrupts = <GIC_SPI 393 IRQ_TYPE_EDGE_RISING>;
33		ranges;
34		status = "disabled";
35
36		dwc3@2690000 {
37			compatible = "synopsys,dwc3";
38			reg = <0x2690000 0x70000>;
39			interrupts = <GIC_SPI 393 IRQ_TYPE_EDGE_RISING>;
40			usb-phy = <&usb_phy>, <&usb_phy>;
