Kernel driver `adm1025.o'
=========================
Status: Complete, known to work but not heavily tested
Supported chips:
* Analog Devices ADM1025
Prefix: 'adm1025'
Addresses scanned: I2C 0x2c - 0x2e
Datasheet: Publicly available at the Analog Devices website
* Philips NE1619
Prefix: 'ne1619'
Addresses scanned: I2C 0x2c - 0x2d
Datasheet: Publicly available at the Philips website
The NE1619 presents some differences with the original ADM1025:
* Only two possible addresses (0x2c - 0x2d).
* No temperature offset register, but we don't use it anyway.
* No INT mode for pin 16. We don't play with it anyway.

Description
-----------
(This is from Analog Devices.) The ADM1025 is a complete system hardware
monitor for microprocessor-based systems, providing measurement and limit
comparison of various system parameters. Five voltage measurement inputs
are provided, for monitoring +2.5V, +3.3V, +5V and +12V power supplies and
the processor core voltage. The ADM1025 can monitor a sixth power-supply
voltage by measuring its own VCC. One input (two pins) is dedicated to a
remote temperature-sensing diode and an on-chip temperature sensor allows
ambient temperature to be monitored.
One specificity of this chip is that the pin 11 can be hardwired in two
different manners. It can act as the +12V power-supply voltage analog
input, or as the a fifth digital entry for the VID reading (bit 4). It's
kind of strange since both are useful, and the reason for designing the
chip that way is obscure at least to me. The bit 5 of the configuration
register can be used to define how the chip is hardwired. Please note
that it is not a choice you have to make as the user. The choice was
already made by your motherboard's maker. If the configuration bit isn't
set properly, you'll have a wrong +12V reading or a wrong VID reading.
The way the driver handles that is to preserve this bit through the
initialization process, assuming that the BIOS set it up properly
beforehand. If it turns out not to be true in some cases, we'll provide
a module parameter to force modes.
