+SYNOPSIS DWC3 CORE
+
+DWC3- USB3 CONTROLLER
+
+Required properties:
+ - compatible: Should be "synopsis,dwc3"
+ - reg : Address and length of the register set for the device
+ - interrupts: Interrupts used by the dwc3 controller.
+ - interrupt-parent: the phandle for the interrupt controller that
+ services interrupts for this device.
+
+Optional properties:
+ - tx-fifo-resize: determines if the fifo spaces can be reallocated according
+ to use-cases.
+
+This is usually a subnode to DWC3 glue to which it is connected.
