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