19*7ebd8b66SMauro Carvalho Chehab-----------
20*7ebd8b66SMauro Carvalho Chehab
21*7ebd8b66SMauro Carvalho ChehabThe Texas Instruments TMP102 implements one temperature sensor.  Limits can be
22*7ebd8b66SMauro Carvalho Chehabset through the Overtemperature Shutdown register and Hysteresis register.  The
23*7ebd8b66SMauro Carvalho Chehabsensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0
24*7ebd8b66SMauro Carvalho Chehabdegree from -40 to +125 C. Resolution of the sensor is 0.0625 degree.  The
25*7ebd8b66SMauro Carvalho Chehaboperating temperature has a minimum of -55 C and a maximum of +150 C.
26*7ebd8b66SMauro Carvalho Chehab
27*7ebd8b66SMauro Carvalho ChehabThe TMP102 has a programmable update rate that can select between 8, 4, 1, and
28*7ebd8b66SMauro Carvalho Chehab0.5 Hz. (Currently the driver only supports the default of 4 Hz).
29*7ebd8b66SMauro Carvalho Chehab
30*7ebd8b66SMauro Carvalho ChehabThe driver provides the common sysfs-interface for temperatures (see
31*7ebd8b66SMauro Carvalho ChehabDocumentation/hwmon/sysfs-interface.rst under Temperatures).
