* 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
