Hello,
This is a patch for the linux-2.6.11.4 kernel that adds the driver
for the VIA vt1211 hw-sensor chip.
The driver is written by Mark D. Studebaker, I have just ported it to
the 2.6 kernel series from 2.4.
Best Regards,

+ Updates (latest first):
+
+ Sat Mar 19 11:23:36 CET 2005 -
+ Preparations for official release;
+ - Remove all the #ifdef stuff (ALL_SENSORS and no convertion
+ is now default).
+ - Remove normal_xxx_range defines which cause compile warnings.
+ - Remove uch_config initialization in vt1211_init_client
+ (trust the BIOS initialization instead, or use setting in
+ sensors.conf)
+ Tue Oct 5 17:17:01 CEST 2004 -
+ Corrected faulty return value in "show_temp_hyst()".
+ Sun Sep 26 09:14:36 CEST 2004 -
