help
Enabling this option will add specific SMBus support for the Tyan
S4882 motherboard. On this 4-CPU board, the SMBus is multiplexed
over 8 different channels, where the various memory module EEPROMs
and temperature sensors live. Saying yes here will give you access
to these in addition to the trunk.
This driver can also be built as a module. If so, the module
will be called i2c-amd756-s4882.

/*
* lm63.c - driver for the National Semiconductor LM63 temperature sensor
* with integrated fan control
* Copyright (C) 2004 Jean Delvare <khali@linux-fr.org>
* Based on the lm90 driver.
*
* The LM63 is a sensor chip made by National Semiconductor. It measures
* two temperatures (its own and one external one) and the speed of one
* fan, those speed it can additionally control. Complete datasheet can be
* obtained from National's website at:
* http://www.national.com/pf/LM/LM63.html
*
* The LM63 is basically an LM86 with fan speed monitoring and control
* capabilities added. It misses some of the LM86 features though:
* - No low limit for local temperature.
* - No critical limit for local temperature.
* - Critical limit for remote temperature can be changed only once. We
* will consider that the critical limit is read-only.
*
* The datasheet isn't very clear about what the tachometer reading is.
* I had a explanation from National Semiconductor though. The two lower
* bits of the read value have to be masked out. The value is still 16 bit
* in width.
