The TMP102 has a programmable update rate that can select between 8, 4, 1, and

0.5 Hz. (Currently the driver only supports the default of 4 Hz).



The TMP110 and TMP113 are software compatible with TMP102, but have different

accuracy (maximum error) specifications. The TMP110 has an accuracy (maximum error)

of 1.0 degree, TMP113 has an accuracy (maximum error) of 0.3 degree, while TMP102

has an accuracy (maximum error) of 2.0 degree.



The driver provides the common sysfs-interface for temperatures (see

Documentation/hwmon/sysfs-interface.rst under Temperatures).
