* Description:
* up_buttoninit() must be called to initialize button resources. After
* that, up_buttons() may be called to collect the current state of all
* buttons or up_irqbutton() may be called to register button interrupt
* handlers.
*
* After up_buttoninit() has been called, up_buttons() may be called to
* collect the state of all buttons. up_buttons() returns an 8-bit bit set
* with each bit associated with a button. See the BUTTON_*_BIT
* definitions in board.h for the meaning of each bit.
*
* up_irqbutton() may be called to register an interrupt handler that will
* be called when a button is depressed or released. The ID value is a
* button enumeration value that uniquely identifies a button resource. See the
* BUTTON_* definitions in board.h for the meaning of enumeration
* value. The previous interrupt handler address is returned (so that it may
* restored, if so desired).
