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. | |
