 * Name:  stm32_usbpullup
 *
 * Description:
 *   If USB is supported and the board supports a pullup via GPIO (for USB software
 *   connect and disconnect), then the board software must provide stm32_pullup.
 *   See include/nuttx/usb/usbdev.h for additional description of this method.

 * Name:  stm32_usbsuspend
 *
 * Description:
 *   Board logic must provide the stm32_usbsuspend logic if the USBDEV driver is
 *   used.  This function is called whenever the USB enters or leaves suspend mode.
 *   This is an opportunity for the board logic to shutdown clocks, power, etc.
 *   while the USB is suspended.
