This driver implements support for Texas Instruments TMP401, TMP411, |
c0a686018 hwmon: (tmp401) A... |

TMP431, TMP432, TMP435, and TMP461 chips. These chips implement one or two remote and one local temperature sensors. Temperature is measured in degrees |

Celsius. Resolution of the remote sensor is 0.0625 degree. Local sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not supported by the driver so far, so using the default resolution of 0.5 degree). The driver provides the common sysfs-interface for temperatures (see |

Documentation/hwmon/sysfs-interface under Temperatures). |

TMP461 is compatible with TMP401. It supports offset correction that is applied to the remote sensor. * Sensor offset values are temperature values Exported via sysfs attribute tempX_offset |
