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. | |

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 | |
