NOTES:

/*
* Changes:
*
* 2002.09.09 Takashi Iwai <tiwai@suse.de>
* split the code to several files. each low-level routine
* is stored in the local file and called from registration
* function from card_info struct.
*
* 2002.11.26 James Stafford <jstafford@ampltd.com>
* Added support for VT1724 (Envy24HT)
* I have left out support for 176.4 and 192 KHz for the moment.
* I also haven't done anything with the internal S/PDIF transmitter or the MPU-401
*
* 2003.02.20 Taksahi Iwai <tiwai@suse.de>
* Split vt1724 part to an independent driver.
* The GPIO is accessed through the callback functions now.
*
* 2004.03.31 Doug McLain <nostar@comcast.net>
* Added support for Event Electronics EZ8 card to hoontech.c.
