This driver supports hardware montoring for Analog Devices ADM1075, ADM1275,

and ADM1276 Hot-Swap Controller and Digital Power Monitor.

ADM1276, ADM1293, and ADM1294 Hot-Swap Controller and Digital Power Monitors.

ADM1075, ADM1275, and ADM1276 are hot-swap controllers that allow a circuit

board to be removed from or inserted into a live backplane. They also feature

current and voltage readback via an integrated 12-bit analog-to-digital

converter (ADC), accessed using a PMBus interface.

These chips are 'Super I/O chips', supporting floppy disks, infrared ports,

joysticks and other miscellaneous stuff. For hardware monitoring, they

have support for 2 additional fans. The additional fans are supported by the

driver.

counters for fans 1 to 3. This is better (no more fan clock divider mess) but

not compatible with the older chips and revisions. The 16-bit tachometer mode

is enabled by the driver when one of the above chips is detected.

The IT8726F is just bit enhanced IT8716F with additional hardware

The IT8790E supports up to 3 fans. 16-bit fan mode is always enabled.

The IT8732F supports a closed-loop mode for fan control, but this is not

currently implemented by the driver.

Temperatures are measured in degrees Celsius. An alarm is triggered once

when the Overtemperature Shutdown limit is crossed.

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 (except IT8603E, IT8721F/IT8758E and IT8728F: 0.012 volt.) The

battery voltage in8 does not have limit registers.

voltage inputs can measure voltages between 0 and 4.08 volts, with a resolution

3.06 volts, with a resolution of 0.012 volt.  IT8732F can measure between 0 and

2.8 volts with a resolution of 0.0109 volt.  The battery voltage in8 does not
