synopsys DWC3 CORE
DWC3- USB3 CONTROLLER
Required properties:
- compatible: must be "snps,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. The first element
in the array is expected to be a handle to the USB2/HS PHY and
the second element is expected to be a handle to the USB3/SS PHY
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.
