+DWC3- USB3 CONTROLLER
+
+Required properties:
+ - compatible: must be "synopsys,dwc3"
+ - reg : Address and length of the register set for the device
+ - interrupts: Interrupts used by the dwc3 controller.
+ - usb-phy : array of phandle for the PHY device
+
+Optional properties:
+ - tx-fifo-resize: determines if the FIFO *has* to be reallocated.
+
+This is usually a subnode to DWC3 glue to which it is connected.
