1 /*
2 * Synaptics TouchPad PS/2 mouse driver
3 *
4 * 2003 Dmitry Torokhov <dtor@mail.ru>
5 * Added support for pass-through port. Special thanks to Peter Berg Larsen
6 * for explaining various Synaptics quirks.
7 *
8 * 2003 Peter Osterlund <petero2@telia.com>
9 * Ported to 2.5 input device infrastructure.
10 *
11 * Copyright (C) 2001 Stefan Gmeiner <riddlebox@freesurf.ch>
12 * start merging tpconfig and gpm code to a xfree-input module
13 * adding some changes and extensions (ex. 3rd and 4th button)
14 *
15 * Copyright (c) 1997 C. Scott Ananian <cananian@alumni.priceton.edu>
16 * Copyright (c) 1998-2000 Bruce Kalk <kall@compass.com>
