/*
 * drivers/input/adbhid.c
 *
 * ADB HID driver for Power Macintosh computers.
 *
 * Adapted from drivers/macintosh/mac_keyb.c by Franz Sirl
 * (see that file for its authors and contributors).
 *
 * Copyright (C) 2000 Franz Sirl.
 *
 * Adapted to ADB changes and support for more devices by
 * Benjamin Herrenschmidt. Adapted from code in MkLinux
 * and reworked.
 *
 * Supported devices:
 *
 * - Standard 1 button mouse
 * - All standard Apple Extended protocol (handler ID 4)
 * - mouseman and trackman mice & trackballs
 * - PowerBook Trackpad (default setup: enable tapping)
 * - MicroSpeed mouse & trackball (needs testing)
 * - CH Products Trackball Pro (needs testing)
 * - Contour Design (Contour Mouse)
 * - Hunter digital (NoHandsMouse)
 * - Kensignton TurboMouse 5 (needs testing)
 * - Mouse Systems A3 mice and trackballs <aidan@kublai.com>
 * - MacAlly 2-buttons mouse (needs testing) <pochini@denise.shiny.it>
 *
 * To do:
 *
 * Improve Kensington support.
