*
|
|
* 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.
