Input: adbhid - produce all CapsLock key events
[deliverable/linux.git] / drivers / macintosh / adbhid.c
1 /*
2 * drivers/macintosh/adbhid.c
3 *
4 * ADB HID driver for Power Macintosh computers.
5 *
6 * Adapted from drivers/macintosh/mac_keyb.c by Franz Sirl.
7 * drivers/macintosh/mac_keyb.c was Copyright (C) 1996 Paul Mackerras
8 * with considerable contributions from Ben Herrenschmidt and others.
9 *
10 * Copyright (C) 2000 Franz Sirl.
11 *
12 * Adapted to ADB changes and support for more devices by
13 * Benjamin Herrenschmidt. Adapted from code in MkLinux
14 * and reworked.
15 *
16 * Supported devices:
17 *
18 * - Standard 1 button mouse
19 * - All standard Apple Extended protocol (handler ID 4)
20 * - mouseman and trackman mice & trackballs
21 * - PowerBook Trackpad (default setup: enable tapping)
22 * - MicroSpeed mouse & trackball (needs testing)
23 * - CH Products Trackball Pro (needs testing)
24 * - Contour Design (Contour Mouse)
25 * - Hunter digital (NoHandsMouse)
26 * - Kensignton TurboMouse 5 (needs testing)
27 * - Mouse Systems A3 mice and trackballs <aidan@kublai.com>
28 * - MacAlly 2-buttons mouse (needs testing) <pochini@denise.shiny.it>
29 *
30 * To do:
31 *
32 * Improve Kensington support.
33 * Split mouse/kbd
34 * Move to syfs
