19*4882a593Smuzhiyun-----------
20*4882a593Smuzhiyun
21*4882a593SmuzhiyunThe Texas Instruments TMP102 implements one temperature sensor.  Limits can be
22*4882a593Smuzhiyunset through the Overtemperature Shutdown register and Hysteresis register.  The
23*4882a593Smuzhiyunsensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0
24*4882a593Smuzhiyundegree from -40 to +125 C. Resolution of the sensor is 0.0625 degree.  The
25*4882a593Smuzhiyunoperating temperature has a minimum of -55 C and a maximum of +150 C.
26*4882a593Smuzhiyun
27*4882a593SmuzhiyunThe TMP102 has a programmable update rate that can select between 8, 4, 1, and
28*4882a593Smuzhiyun0.5 Hz. (Currently the driver only supports the default of 4 Hz).
29*4882a593Smuzhiyun
30*4882a593SmuzhiyunThe driver provides the common sysfs-interface for temperatures (see
31*4882a593SmuzhiyunDocumentation/hwmon/sysfs-interface.rst under Temperatures).
