- * Copyright (C) by Hannu Savolainen 1993-1997
- *
- * mad16.c
- *
- * Initialization code for OPTi MAD16 compatible audio chips. Including
- *
- * OPTi 82C928 MAD16 (replaced by C929)
- * OAK OTI-601D Mozart
- * OAK OTI-605 Mozart (later version with MPU401 Midi)
- * OPTi 82C929 MAD16 Pro
- * OPTi 82C930
- * OPTi 82C924
- *
- * These audio interface chips don't produce sound themselves. They just
- * connect some other components (OPL-[234] and a WSS compatible codec)
- * to the PC bus and perform I/O, DMA and IRQ address decoding. There is
- * also a UART for the MPU-401 mode (not 82C928/Mozart).
- * The Mozart chip appears to be compatible with the 82C928, although later
- * issues of the card, using the OTI-605 chip, have an MPU-401 compatible Midi
- * port. This port is configured differently to that of the OPTi audio chips.
- *
- * Changes
- *
- * Alan Cox Clean up, added module selections.
- *
- * A. Wik Added support for Opti924 PnP.
- * Improved debugging support. 16-May-1998
- * Fixed bug. 16-Jun-1998
- *
- * Torsten Duwe Made Opti924 PnP support non-destructive
- * 23-Dec-1998
- *
- * Paul Grayson Added support for Midi on later Mozart cards.
- * 25-Nov-1999
- * Christoph Hellwig Adapted to module_init/module_exit.
- * Arnaldo C. de Melo got rid of attach_uart401 21-Sep-2000
- *
- * Pavel Rabel Clean up Nov-2000
