Maxim MAX663x family are mostly compatible with LM92, but they lack any identification register. Weakening the detect function would make it prone to false positives, and current one doesn't detect all chips. Therefore, the detect function for max6635 devices is removed in favor of explicit device instatiation.

Description
|
|
-----------
|
|
|
|
This driver implements support for the National Semiconductor LM92
|
|
temperature sensor.
|
|
|
|
Each LM92 temperature sensor supports a single temperature sensor. There are
|
|
alarms for high, low, and critical thresholds. There's also an hysteresis to
|
|
control the thresholds for resetting alarms.
|
|
|
|
Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635,
|
|
which are mostly compatible. They have not all been tested, so you
|
|
may need to use the force parameter.
