|
|
* ADB HID driver for Power Macintosh computers.
|
|
*
|
|
* Adapted from drivers/macintosh/mac_keyb.c by Franz Sirl.
|
|
* drivers/macintosh/mac_keyb.c was Copyright (C) 1996 Paul Mackerras

|
|
* 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.
|
|
* Split mouse/kbd
|
|
* Move to syfs
