| 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 |

| 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 |
