24 * Ported to 386bsd Oct 17, 1992
25 * Sandi Donno, Computer Science, University of Cape Town, South Africa
26 * Please send bug reports to sandi@cs.uct.ac.za
27 *
28 * Thanks are also due to Rick Macklem, rick@snowhite.cis.uoguelph.ca -
29 * although I was only partially successful in getting the alpha release
30 * of his "driver for the Logitech and ATI Inport Bus mice for use with
31 * 386bsd and the X386 port" to work with my Microsoft mouse, I nevertheless
32 * found his code to be an invaluable reference when porting this driver
33 * to 386bsd.
34 *
35 * Further modifications for latest 386BSD+patchkit and port to NetBSD,
36 * Andrew Herbert <andrew@werple.apana.org.au> - 8 June 1993
37 *
38 * Cloned from the Microsoft Bus Mouse driver, also by Erik Forsberg, by
39 * Andrew Herbert - 12 June 1993
40 *
41 * Modified for PS/2 mouse by Charles Hannum <mycroft@ai.mit.edu>
42 * - 13 June 1993
43 *
44 * Modified for PS/2 AUX mouse by Shoji Yuen <yuen@nuie.nagoya-u.ac.jp>
45 * - 24 October 1993
46 *
47 * Hardware access routines and probe logic rewritten by
48 * Kazutaka Yokota <yokota@zodiac.mech.utsunomiya-u.ac.jp>
49 * - 3, 14, 22 October 1996.
50 * - 12 November 1996. IOCTLs and rearranging `psmread', `psmioctl'...
51 * - 14, 30 November 1996. Uses `kbdio.c'.
52 * - 13 December 1996. Uses queuing version of `kbdio.c'.
91be4d71 53 * - January/February 1997. Tweaked probe logic for
984263bc
MD
54 * HiNote UltraII/Latitude/Armada laptops.
55 * - 30 July 1997. Added APM support.
91be4d71 56 * - 5 March 1997. Defined driver configuration flags (PSM_CONFIG_XXX).
984263bc
MD
57 * Improved sync check logic.
58 * Vendor specific support routines.
