* This structure defines the mapping of certain auxiliary functions to the
* MAX3421E GPIO pins. The chip has eight GP inputs and eight GP outputs.
* A value of 0 indicates that the pin is not used/wired to anything.
*
* At this point, the only control the max3421-hcd driver cares about is
* to control Vbus (5V to the peripheral).
