[PATCH 2/2] hwmon: tmp102: Add support for TMP110 and TMP113 devices

[Flaviu Nistor <flaviu.nistor@gmail.com>]

TMP110 and TMP113 temperature sensors are software compatible
with TMP102 sensor but have different accuracy (maximum error).

 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).
