/** \file
* This file provides access to:
* - global variables available to all hw/dmx routines, and
* - enumerations and typedefs needed by input routines in hw/dmx (and
* hw/dmx/input).
*
* The goal is that no files in hw/dmx should include header files from
* hw/dmx/input -- the interface defined here should be the only
* interface exported to the hw/dmx layer. \see input/dmxinputinit.c.
