|
|
*
|
|
* 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.
