 * 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.
