| 4 | * mad16.c |
| 5 | * |
| 6 | * Initialization code for OPTi MAD16 compatible audio chips. Including |
| 7 | * |
| 8 | * OPTi 82C928 MAD16 (replaced by C929) |
| 9 | * OAK OTI-601D Mozart |
| 10 | * OAK OTI-605 Mozart (later version with MPU401 Midi) |
| 11 | * OPTi 82C929 MAD16 Pro |
| 12 | * OPTi 82C930 |
| 13 | * OPTi 82C924 |
| 14 | * |
| 15 | * These audio interface chips don't produce sound themselves. They just |
| 16 | * connect some other components (OPL-[234] and a WSS compatible codec) |
| 17 | * to the PC bus and perform I/O, DMA and IRQ address decoding. There is |
| 18 | * also a UART for the MPU-401 mode (not 82C928/Mozart). |
| 19 | * The Mozart chip appears to be compatible with the 82C928, although later |
| 20 | * issues of the card, using the OTI-605 chip, have an MPU-401 compatible Midi |
| 21 | * port. This port is configured differently to that of the OPTi audio chips. |
| 22 | * |
| 23 | * Changes |
| 24 | * |
| 25 | * Alan Cox Clean up, added module selections. |
| 26 | * |
| 27 | * A. Wik Added support for Opti924 PnP. |
| 28 | * Improved debugging support. 16-May-1998 |
| 29 | * Fixed bug. 16-Jun-1998 |
| 30 | * |
| 31 | * Torsten Duwe Made Opti924 PnP support non-destructive |
| 32 | * 23-Dec-1998 |
| 33 | * |
| 34 | * Paul Grayson Added support for Midi on later Mozart cards. |
| 35 | * 25-Nov-1999 |
| 36 | * Christoph Hellwig Adapted to module_init/module_exit. |
| 37 | * Arnaldo C. de Melo got rid of attach_uart401 21-Sep-2000 |
| 38 | * |
| 39 | * Pavel Rabel Clean up Nov-2000 |
