* f71805f.c - driver for the Fintek F71805F/FG and F71872F/FG Super-I/O
|
|
* chips integrated hardware monitoring features
|
|
* Copyright (C) 2005-2006 Jean Delvare <khali@linux-fr.org>
|
|
*
|
|
* The F71805F/FG is a LPC Super-I/O chip made by Fintek. It integrates
|
|
* complete hardware monitoring features: voltage, fan and temperature
|
|
* sensors, and manual and automatic fan speed control.
|
|
*
|
|
* The F71872F/FG is almost the same, with two more voltages monitored,
|
|
* and 6 VID inputs.
|
|
*
|
|
* The F71806F/FG is essentially the same as the F71872F/FG. It even has
|
|
* the same chip ID, so the driver can't differentiate between.
