- *
- * AD1816 lowlevel sound driver for Linux 2.6.0 and above
- *
- * Copyright (C) 1998-2003 by Thorsten Knabe <linux@thorsten-knabe.de>
- *
- * Based on the CS4232/AD1848 driver Copyright (C) by Hannu Savolainen 1993-1996
- *
- *
- * version: 1.5
- * status: beta
- * date: 2003/07/15
- *
- * Changes:
- * Oleg Drokin: Some cleanup of load/unload functions. 1998/11/24
- *
- * Thorsten Knabe: attach and unload rewritten,
- * some argument checks added 1998/11/30
- *
- * Thorsten Knabe: Buggy isa bridge workaround added 1999/01/16
- *
- * David Moews/Thorsten Knabe: Introduced options
- * parameter. Added slightly modified patch from
- * David Moews to disable dsp audio sources by setting
- * bit 0 of options parameter. This seems to be
- * required by some Aztech/Newcom SC-16 cards. 1999/04/18
- *
- * Christoph Hellwig: Adapted to module_init/module_exit. 2000/03/03
- *
- * Christoph Hellwig: Added isapnp support 2000/03/15
- *
- * Arnaldo Carvalho de Melo: get rid of check_region 2001/10/07
- *
- * Thorsten Knabe: Compiling with CONFIG_PNP enabled
- * works again. It is now possible to use more than one
- * AD1816 sound card. Sample rate now may be changed during
- * playback/capture. printk() uses log levels everywhere.
- * SMP fixes. DMA handling fixes.
- * Other minor code cleanup. 2003/07/15
- *
