0006  *
0007  * The F71805F/FG is a LPC Super-I/O chip made by Fintek. It integrates
0008  * complete hardware monitoring features: voltage, fan and temperature
0009  * sensors, and manual and automatic fan speed control.
0010  *
0011  * The F71872F/FG is almost the same, with two more voltages monitored,
0012  * and 6 VID inputs.
0013  *
0014  * The F71806F/FG is essentially the same as the F71872F/FG. It even has
0015  * the same chip ID, so the driver can't differentiate between.
