1 | /* |
2 | * linux/drivers/char/keyboard.c |
3 | * |
4 | * Written for linux by Johan Myreen as a translation from |
5 | * the assembly version by Linus (with diacriticals added) |
6 | * |
7 | * Some additional features added by Christoph Niemann (ChN), March 1993 |
8 | * |
9 | * Loadable keymaps by Risto Kankkunen, May 1993 |
10 | * |
11 | * Diacriticals redone & other small changes, aeb@cwi.nl, June 1993 |
12 | * Added decr/incr_console, dynamic keymaps, Unicode support, |
13 | * dynamic function/string keys, led setting, Sept 1994 |
14 | * `Sticky' modifier keys, 951006. |
15 | * |
16 | * 11-11-96: SAK should now work in the raw mode (Martin Mares) |
17 | * |
18 | * Modified to provide 'generic' keyboard support by Hamish Macdonald |
19 | * Merge with the m68k keyboard driver and split-off of the PC low-level |
20 | * parts by Geert Uytterhoeven, May 1997 |
21 | * |
22 | * 27-05-97: Added support for the Magic SysRq Key (Martin Mares) |
23 | * 30-07-98: Dead keys redone, aeb@cwi.nl. |
24 | * 21-08-02: Converted to input API, major cleanup. (Vojtech Pavlik) |
