Description
-----------
This driver implements support for the IT8705F chip.
This chip is also known as SIS 950.
This driver also supports IT8712F, which adds SmBus access, and a Vid
input, used to report the Vcore voltage of the Pentium processor.
These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
joysticks and other miscellaneous stuff. For hardware monitoring,
they include an 'environmnent controller' with 3 temperature sensors,
3 FAN rotation speed sensors, 8 voltage sensors, and associated alarms.
Temperatures are measured in degrees Celcius. An alarm is triggered once
when the Overtemperature Shutdown limit is crossed; it is triggered again
as soon as it drops below the Hysteresis value.
FAN rotation speeds are reported in RPM (rotations per minute). An alarm is
triggered if the rotation speed has dropped below a programmable limit. FAN
readings can be divided by a programmable divider (1, 2, 4 or 8) to give
the readings more range or accuracy. This is important because some FANs
report only one 'tick' each rotation, while others report two - making
all readings twice as high. Not all RPM values can accurately be represented,
so some rounding is done. With a divider of 2, the lowest representable
value is around 2600 RPM.
Voltage sensors (also known as IN sensors) report their values in volts.
An alarm is triggered if the voltage has crossed a programmable minimum
or maximum limit. Note that minimum in this case always means 'closest to
zero'; this is important for negative voltage measurements. All voltage
inputs can measure voltages between 0 and 4.08 volts, with a resolution
of 0.016 volt.
The VID lines (IT8712F only) encode the core voltage value: the voltage level
your processor should work with. This is hardcoded by the mainboard and/or
processor itself. It is a value in volts.
If an alarm triggers, it will remain triggered until the hardware register
is read at least once. This means that the cause for the alarm may
already have disappeared! Note that in the current implementation, all
hardware registers are read whenever any data is read (unless it is less
than 1.5 seconds since the last update). This means that you can easily
miss once-only alarms.
The IT87xx only updates its values each 1.5 seconds; reading it more often
will do no harm, but will return 'old' values.

you can assume it is large enough. */
