* Filename: w83977af_ir.c
* Version: 1.0
* Description: FIR driver for the Winbond W83977AF Super I/O chip
* Status: Experimental.
* Author: Paul VanderSpek
* Created at: Wed Nov 4 11:46:16 1998
* Modified at: Fri Jan 28 12:10:59 2000

* similar.
*
* Notice that all functions that needs to access the chip in _any_
* way, must save BSR register on entry, and restore it on exit.
* It is _very_ important to follow this policy!
