config I2C_MAINBOARD
bool "Hardware sensors mainboard support"
depends on EXPERIMENTAL && I2C && I2C_PROC
help
Many modern mainboards have some kind of I2C interface integrated. This
is often in the form of a SMBus, or System Management Bus, which is
basically the same as I2C but which uses only a subset of the I2C
protocol.
You will also want the latest user-space utilties: you can find them
in the lm_sensors package, which you can download at
http://www.lm-sensors.nu
config I2C_AMD756
tristate " AMD 756/766"
depends on I2C_MAINBOARD
help
If you say yes to this option, support will be included for the AMD
756/766/768 mainboard I2C interfaces.
This can also be built as a module which can be inserted and removed
while the kernel is running. If you want to compile it as a module,
say M here and read <file:Documentation/modules.txt>.
The module will be called i2c-amd756.o.
You will also need the latest user-space utilties: you can find them
in the lm_sensors package, which you can download at

Many modern mainboards have some kind of I2C interface integrated.
This is often in the form of a SMBus, or System Management Bus, which
is basically the same as I2C but which uses only a subset of the I2C
protocol.
You will also want the latest user-space utilties: you can find them
in the lm_sensors package, which you can download at
http://www.lm-sensors.nu

If you say yes here you get support for Analog Devices ADM1021
and ADM1023 sensor chips and clones: Maxim MAX1617 and MAX1617A,
Genesys Logic GL523SM, National Semi LM84, TI THMC10,
and the XEON processor built-in sensor. This can also
be built as a module which can be inserted and removed while the
kernel is running.
The module will be called adm1021.o.
