 28 /*
 29  * Changes:
 30  *
 31  *  2002.09.09  Takashi Iwai <tiwai@suse.de>
 32  *      split the code to several files.  each low-level routine
 33  *      is stored in the local file and called from registration
 34  *      function from card_info struct.
 35  *
 36  *  2002.11.26  James Stafford <jstafford@ampltd.com>
 37  *      Added support for VT1724 (Envy24HT)
 38  *      I have left out support for 176.4 and 192 KHz for the moment.
 39  *  I also haven't done anything with the internal S/PDIF transmitter or the MPU-401
 40  *
 41  *  2003.02.20  Taksahi Iwai <tiwai@suse.de>
 42  *      Split vt1724 part to an independent driver.
 43  *      The GPIO is accessed through the callback functions now.
 44  *
 45  * 2004.03.31 Doug McLain <nostar@comcast.net>
 46  *    Added support for Event Electronics EZ8 card to hoontech.c.
