/*

* The low level init and interrupt stuff is handled in arch/mm68k/atari/atakeyb.c
|
|
* (the keyboard ACIA also handles the mouse and joystick data, and the keyboard
|
|
* interrupt is shared with the MIDI ACIA so MIDI data also get handled there).
|
|
* This driver only deals with handing key events off to the input layer.
|
|
*
|
|
* Largely based on the old:

|
* Atari Mouse Driver for Linux
|
|
* by Robert de Vries (robert@and.nl) 19Jul93
|
|
*
|
|
* 16 Nov 1994 Andreas Schwab
|
|
* Compatibility with busmouse
|
|
* Support for three button mouse (shamelessly stolen from MiNT)
|
|
* third button wired to one of the joystick directions on joystick 1
|
|
*
|
|
* 1996/02/11 Andreas Schwab
|
|
* Module support
|
|
* Allow multiple open's
|
|
*
|
|
* Converted to use new generic busmouse code. 5 Apr 1998
