36*4882a593SmuzhiyunDescription
37*4882a593Smuzhiyun-----------
38*4882a593Smuzhiyun
39*4882a593SmuzhiyunThis driver implements support for the National Semiconductor LM92
40*4882a593Smuzhiyuntemperature sensor.
41*4882a593Smuzhiyun
42*4882a593SmuzhiyunEach LM92 temperature sensor supports a single temperature sensor. There are
43*4882a593Smuzhiyunalarms for high, low, and critical thresholds. There's also an hysteresis to
44*4882a593Smuzhiyuncontrol the thresholds for resetting alarms.
45*4882a593Smuzhiyun
46*4882a593SmuzhiyunSupport was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635,
47*4882a593Smuzhiyunwhich are mostly compatible. They have not all been tested, so you
48*4882a593Smuzhiyunmay need to use the force parameter.
