-Description
------------
-
-The LM83 is a digital temperature sensor. It senses its own temperature as
-well as the temperature of up to three external diodes. It is compatible
-with many other devices such as the LM84 and all other ADM1021 clones.
-The main difference between the LM83 and the LM84 in that the later can
-only sense the temperature of one external diode.
-
-Using the adm1021 driver for a LM83 should work, but only two temperatures
-will be reported instead of four.
-
-The LM83 is only found on a handful of motherboards. Both a confirmed
-list and an unconfirmed list follow. If you can confirm or infirm the
-fact that any of these motherboards do actually have an LM83, please
-contact us. Note that the LM90 can easily be misdetected as a LM83.
-
-Confirmed motherboards:
-    SBS         P014
-
-Unconfirmed motherboards:
-    Gigabyte    GA-8IK1100
-    Iwill       MPX2
-    Soltek      SL-75DRV5
-
-The driver has been successfully tested by Magnus Forsström, who I'd
-like to thank here. More testers will be of course welcome.
-
-The fact that the LM83 is only scarcely used can be easily explained.
-Most motherboards come with more than just temperature sensors for
-health monitoring. They also have voltage and fan rotation speed
-sensors. This means that temperature-only chips are usually used as
-secondary chips coupled with another chip such as an IT8705F or similar
-chip, which provides more features. Since systems usually need three
-temperature sensors (motherboard, processor, power supply) and primary
-chips provide some temperature sensors, the secondary chip, if needed,
-won't have to handle more than two temperatures. Thus, ADM1021 clones
-are sufficient, and there is no need for a four temperatures sensor
-chip such as the LM83. The only case where using an LM83 would make
-sense is on SMP systems, such as the above-mentioned Iwill MPX2,
-because you want an additional temperature sensor for each additional
-CPU.
-
-On the SBS P014, this is different, since the LM83 is the only hardware
-monitoring chipset. One temperature sensor is used for the motherboard
-(actually measuring the LM83's own temperature), one is used for the
-CPU. The two other sensors must be used to measure the temperature of
-two other points of the motherboard. We suspect these points to be the
-north and south bridges, but this couldn't be confirmed.
-
-All temperature values are given in degrees Celsius. Local temperature
-is given within a range of 0 to +85 degrees. Remote temperatures are
-given within a range of 0 to +125 degrees. Resolution is 1.0 degree,
-accuracy is guaranteed to 3.0 degrees (see the datasheet for more
-details).
-
-Each sensor has its own high limit, but the critical limit is common to
-all four sensors. There is no hysteresis mechanism as found on most
-recent temperature sensors.
-
-The lm83 driver will not update its values more frequently than every
-other second; reading them more often will do no harm, but will return
-'old' values.
