+ * The VIM3 on-board MCU can mux the PCIe/USB3.0 shared differential
+ * lines using a FUSB340TMX USB 3.1 SuperSpeed Data Switch between
+ * an USB3.0 Type A connector and a M.2 Key M slot.
+ * The PHY driving these differential lines is shared between
+ * the USB3.0 controller and the PCIe Controller, thus only
+ * a single controller can use it.
+ * If the MCU is configured to mux the PCIe/USB3.0 differential lines
+ * to the M.2 Key M slot, uncomment the following block to disable
+ * USB3.0 from the USB Complex and enable the PCIe controller.
+ * The End User is not expected to uncomment the following except for
+ * testing purposes, but instead rely on the firmware/bootloader to
+ * update these nodes accordingly if PCIe mode is selected by the MCU.
