f30c2269 2 * sound/oss/opl3sa2.c
1da177e4
LT		 3 *
4 * A low level driver for Yamaha OPL3-SA2 and SA3 cards.
5 * NOTE: All traces of the name OPL3-SAx have now (December 2000) been
6 * removed from the driver code, as an email exchange with Yamaha
7 * provided the information that the YMF-719 is indeed just a
8 * re-badged 715.
9 *
10 * Copyright 1998-2001 Scott Murray <scott@spiteful.org>
11 *
12 * Originally based on the CS4232 driver (in cs4232.c) by Hannu Savolainen
13 * and others. Now incorporates code/ideas from pss.c, also by Hannu
14 * Savolainen. Both of those files are distributed with the following

26 *
27 * Change History
28 * --------------
29 * Scott Murray Original driver (Jun 14, 1998)
30 * Paul J.Y. Lahaie Changed probing / attach code order
31 * Scott Murray Added mixer support (Dec 03, 1998)
32 * Scott Murray Changed detection code to be more forgiving,
33 * added force option as last resort,
34 * fixed ioctl return values. (Dec 30, 1998)
35 * Scott Murray Simpler detection code should work all the time now
36 * (with thanks to Ben Hutchings for the heuristic),
37 * removed now unnecessary force option. (Jan 5, 1999)
38 * Christoph Hellwig Adapted to module_init/module_exit (Mar 4, 2000)
39 * Scott Murray Reworked SA2 versus SA3 mixer code, updated chipset
40 * version detection code (again!). (Dec 5, 2000)
41 * Scott Murray Adjusted master volume mixer scaling. (Dec 6, 2000)
42 * Scott Murray Based on a patch by Joel Yliluoma (aka Bisqwit),
43 * integrated wide mixer and adjusted mic, bass, treble
44 * scaling. (Dec 6, 2000)
45 * Scott Murray Based on a patch by Peter Englmaier, integrated
46 * ymode and loopback options. (Dec 6, 2000)
47 * Scott Murray Inspired by a patch by Peter Englmaier, and based on
48 * what ALSA does, added initialization code for the
49 * default DMA and IRQ settings. (Dec 6, 2000)
50 * Scott Murray Added some more checks to the card detection code,
51 * based on what ALSA does. (Dec 12, 2000)
52 * Scott Murray Inspired by similar patches from John Fremlin,
53 * Jim Radford, Mike Rolig, and Ingmar Steen, added 2.4
54 * ISA PnP API support, mainly based on bits from
55 * sb_card.c and awe_wave.c. (Dec 12, 2000)
56 * Scott Murray Some small cleanups to the init code output.
57 * (Jan 7, 2001)
58 * Zwane Mwaikambo Added PM support. (Dec 4 2001)
59 *
60 * Adam Belay Converted driver to new PnP Layer (Oct 12, 2002)
61 * Zwane Mwaikambo Code, data structure cleanups. (Feb 15 2002)
62 * Zwane Mwaikambo Free resources during auxiliary device probe
63 * failures (Apr 29 2002)
64 *
