tmp43xtmp401, 411, 43x series I2C temperature sensor driver

/dev/sensors/temperature/i2c/tmp43x*

The tmp43x driver supports the Texas Instruments TMP401, TMP411, TMP431, TMP432, and TMP435 I2C temperature sensor devices. All devices support a “local” sensor and at least one remote sensor called “remote1”. The TMP432 supports a second remote temperature sensor called “remote2”.

All of the sensors are registered with the kernel sensor framework and an interface to them is provied by ksensor(4D). The temperature is measured in units of 1/16th of a degree Celsius and the devices generally have +/-1 degree Celsius of accuracy.

Temperature information is available to the system through the fault management architecture (FMA). The file system location and programming interface to the tmp43x temperature sensors are considered .
