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)
