2 | * f71805f.c - driver for the Fintek F71805F/FG and F71872F/FG Super-I/O |
3 | * chips integrated hardware monitoring features | |

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 | * | |
51c997d8 JD |
10 | * The F71872F/FG is almost the same, with two more voltages monitored, |
11 | * and 6 VID inputs. | |
12 | * | |
9cab0217 JD |
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. | |
