Both controllers share the USB3 PHY which can be configured for either USB3 or PCIe operation. The USB3 XHCI controller supports USB 2.0 and USB 3.0 SuperSpeed operation. The PCIe controller is compatible with PCIe Gen2 specifications. Also add the topmisc syscon node required for USB/PCIe PHY multiplexing.
