Description
-----------

The TMP103 is a digital output temperature sensor in a four-ball
wafer chip-scale package (WCSP). The TMP103 is capable of reading
temperatures to a resolution of 1°C. The TMP103 is specified for
operation over a temperature range of –40°C to +125°C.

Resolution: 8 Bits
Accuracy: ±1°C Typ (–10°C to +100°C)

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

Please refer how to instantiate this driver:
