STATUS:
2014-12-03: As nearly I can tell, the Itead Joystick shield cannot be
used with the SAMA5D3-Xplained. I believe that the EMAC PHY chip is
enableed and since it shares pins with the Joystick, it interferes with
the Joystick inputs. There is probably more wrong than this; perhaps I
am not setting up the pins correctly. But having seen the states of the
button output pins change when powering up the board, I have lost hope
of getting the shield to work on this board. I leave the
implementation in place only for reference.
