* Based on the lm83 driver. The LM90 is a sensor chip made by National
* Semiconductor. It reports up to two temperatures (its own plus up to
* one external one) with a 0.125 deg resolution (1 deg for local
* temperature) and a 3-4 deg accuracy. Complete datasheet can be
* obtained from National's website at:

* This driver also supports the LM89 and LM99, two other sensor chips
* made by National Semiconductor. Both have an increased remote
* temperature measurement accuracy (1 degree), and the LM99
* additionally shifts remote temperatures (measured and limits) by 16
* degrees, which allows for higher temperatures measurement. The
* driver doesn't handle it since it can be done easily in user-space.
* Complete datasheets can be obtained from National's website at:

* http://www.national.com/pf/LM/LM99.html
* Note that there is no way to differentiate between both chips.

* This driver also supports the LM86, another sensor chip made by
* National Semiconductor. It is exactly similar to the LM90 except it
* has a higher accuracy.
