- *
- * 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
- *
