+ * sound/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)
+ *
