| * 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. |
