/*
 * USB0 Peripheral Mode Overlay
 *
 * This overlay switches USB0 from host mode to peripheral mode
 * by configuring the USB controller node.
 *
 * Hardware requirement:
 * The DIP switch SW1 must be toggled to reconnect the USB0 HS
 * differential pair to the Micro-USB connector instead of the
 * on-board USB 3.0 hub.
 *
 * Without toggling SW1, there is no electrical path to the
 * Micro-USB connector and device mode will not function.
