or a thermistor. The driver reports the currently selected mode, but
doesn't allow changing it. In theory, the BIOS should have configured
everything properly.


Fan Control
-----------

Both PWM (pulse-width modulation) and DC fan speed control methods are
supported. The right one to use depends on external circuitry on the
motherboard, so the driver assumes that the BIOS set the method
properly. The driver will report the method, but won't let you change
it.

When the PWM method is used, you can select the operating frequency,
from 187.5 kHz (default) to 31 Hz. The best frequency depends on the
fan model. As a rule of thumb, lower frequencies seem to give better
control, but may generate annoying high-pitch noise. Fintek recommends
not going below 1 kHz, as the fan tachometers get confused by lower
frequencies as well.

When the DC method is used, Fintek recommends not going below 5 V, which
corresponds to a pwm value of 106 for the driver. The driver doesn't
enforce this limit though.

Three different fan control modes are supported:

* Manual mode
You ask for a specific PWM duty cycle or DC voltage.

* Fan speed mode
You ask for a specific fan speed. This mode assumes that pwm1
corresponds to fan1, pwm2 to fan2 and pwm3 to fan3.

* Temperature mode
You define 3 temperature/fan speed trip points, and the fan speed is
adjusted depending on the measured temperature, using interpolation.
This mode is not yet supported by the driver.

Hardware Interfaces
-------------------

All the chips suported by this driver are LPC Super-I/O chips, accessed
through the LPC bus (ISA-like I/O ports). The IT8712F additionally has an
SMBus interface to the hardware monitoring functions. This driver no
longer supports this interface though, as it is slower and less reliable
than the ISA access, and was only available on a small number of
motherboard models.
