74 * The VIM3 on-board  MCU can mux the PCIe/USB3.0 shared differential

77 * The PHY driving these differential lines is shared between

80 * If the MCU is configured to mux the PCIe/USB3.0 differential lines

82 * USB3.0 from the USB Complex and enable the PCIe controller.
83 * The End User is not expected to uncomment the following except for

85 * update these nodes accordingly if PCIe mode is selected by the MCU.
