 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 driver provides the common sysfs-interface for temperatures (see
 Documentation/hwmon/sysfs-interface.rst under Temperatures).

          This driver can also be built as a module. If so, the module
          will be called tmp102.
