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 | * | |
