+Synopsys DesignWareCores SuperSpeed USB 3.0 Controller
+
+The device node for a USB3 Wrapper that is part of an OMAP5 SoC is as described
+in the document "Open Firmware Recommended Practice: Universal Serial Bus" with
+the following modifications and additions:
+
+Required properties:
+ - compatible : should be "ti,omap5-dwc3" or "ti,omap5430-dwc3".
+ - reg : the first address and length contains the address of DRD. The
+ second address and length contains the address of the wrapper.
+ - interrupts : < a b > where 'a' is the interrupt number and 'b' is a
+ field that represents an encoding of the sense and level
+ information for the interrupt line.
+ - child device : The child Synopsys DesignWareCore USB 3.0 DRD Controller
+
+Optional properties:
+ - utmi_mode : UTMI mode of the wrapper Interrupts (SW or HW). Refer to
+ OMAP5 TRM for more details (for TI wrapper only)
+
+Example of hardware mode OMAP5:
+
+ usb@4a020000 {
+ #address-cells = < 1 >;
+ #size-cells = < 1 >;
+ compatible = "ti,omap5430-dwc3", "ti,omap5-dwc3";
+ interrupt-parent = < &intc >;
+ interrupts = < 93 4 >;
+ reg = < 0x4a020000 0x10000 >;
+ utmi_mode = "hardware";
+ range;
+
+ usb@4a030000 {
+ #address-cells = < 3 >;
+ #size-cells = < 3 >;
+ compatible = "synopsys,dwc3";
+ interrupt-parent = < &intc >;
+ interupts = < 92 4 >;
+ reg = < 0x4a030000 0x8000 // First address is xHCI
+ 0x4a03c100 0x600 // Second is Global
+ 0x4a03c700 0x500 >; // Third is Device
+ };
+ };
+
+Example of software mode OMAP5:
+
+ usb@4a020000 {
+ #address-cells = < 1 >;
+ #size-cells = < 1 >;
+ compatible = "ti,omap5430-dwc3", "ti,omap5-dwc3";
+ interrupt-parent = < &intc >;
+ interrupts = < 93 4 >;
+ reg = < 0x4a020000 0x10000 ;
+ utmi_mode = "software";
+ range;
+
+ usb@4a030000 {
+ #address-cells = < 3 >;
+ #size-cells = < 3 >;
+ compatible = "synopsys,dwc3";
+ interrupt-parent = < &intc >;
+ interupts = < 92 4 >;
+ reg = < 0x4a030000 0x8000 // First address is xHCI
+ 0x4a03c100 0x600 // Second is Global
+ 0x4a03c700 0x500 >; // Third is Device
+ };
+ };
