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. |
