* 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.
