* Credits:
*
* This code is based on the FreeBSD driver written by Taku YAMAMOTO
*
*
* Original credits from the FreeBSD driver:
*
* Part of this code (especially in many magic numbers) was heavily inspired
* by the Linux driver originally written by
* Alan Cox <alan.cox@linux.org>, modified heavily by
* Zach Brown <zab@zabbo.net>.
*
* busdma()-ize and buffer size reduction were suggested by
* Cameron Grant <gandalf@vilnya.demon.co.uk>.
* Also he showed me the way to use busdma() suite.
*
* Internal speaker problems on NEC VersaPro's and Dell Inspiron 7500
* were looked at by
* Munehiro Matsuda <haro@tk.kubota.co.jp>,
* who brought patches based on the Linux driver with some simplification.
