2 * f71805f.c - driver for the Fintek F71805F/FG and F71872F/FG Super-I/O
3 * chips integrated hardware monitoring features
4 * Copyright (C) 2005-2006 Jean Delvare <khali@linux-fr.org>
5 *
6 * The F71805F/FG is a LPC Super-I/O chip made by Fintek. It integrates
7 * complete hardware monitoring features: voltage, fan and temperature
8 * sensors, and manual and automatic fan speed control.
9 *
10 * The F71872F/FG is almost the same, with two more voltages monitored,
11 * and 6 VID inputs.
12 *
13 * The F71806F/FG is essentially the same as the F71872F/FG. It even has
14 * the same chip ID, so the driver can't differentiate between.
