+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.
