Raw Blame History

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

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