* Cadence USB3 Controller
Required properties:
- compatible: "Cadence,usb3";
- reg: base address and length of the registers
- interrupts: interrupt for the USB controller
- interrupt-parent: the interrupt parent for this module
- clocks: reference to the USB clock
- clock-names: the name of clocks
- cdns3,usbphy: reference to the USB PHY
Optional properties:
- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"
- extcon: extcon phandler for cdns3 device
- power-domains: the power domain for cdns3 controller and phy
Examples:
