If you say yes here you get support for National Semiconductor LM90,
LM86, LM89 and LM99, Analog Devices ADM1032 and ADT7461, and Maxim
- MAX6646, MAX6647, MAX6649, MAX6657, MAX6658, MAX6659, MAX6680 and
- MAX6681 sensor chips.
+ MAX6646, MAX6647, MAX6648, MAX6649, MAX6657, MAX6658, MAX6659,
+ MAX6680, MAX6681 and MAX6692 sensor chips.
This driver can also be built as a module. If so, the module
will be called lm90.
