15 | * Atari keyboard driver for Linux/m68k | |
16 | * | |
17 | * The low level init and interrupt stuff is handled in arch/mm68k/atari/atakeyb.c | |
18 | * (the keyboard ACIA also handles the mouse and joystick data, and the keyboard | |
19 | * interrupt is shared with the MIDI ACIA so MIDI data also get handled there). | |
20 | * This driver only deals with handing key events off to the input layer. | |
