These chips implement one or two 64remote and one local temperature sensors. Temperature is measured in degrees 65Celsius. Resolution of the remote sensor is 0.0625 degree. Local 66sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not 67supported by the driver so far, so using the default resolution of 0.5 68degree). 69 70The driver provides the common sysfs-interface for temperatures (see 71Documentation/hwmon/sysfs-interface.rst under Temperatures). 72 73The TMP411 and TMP431 chips are compatible with TMP401. TMP411 provides 74some additional features. 75 76* Minimum and Maximum temperature measured since power-on, chip-reset 77 78 Exported via sysfs attributes tempX_lowest and tempX_highest. 79 80* Reset of historical minimum/maximum temperature measurements 81 82 Exported via sysfs attribute temp_reset_history. Writing 1 to this 83 file triggers a reset. 84 85TMP432 is compatible with TMP401 and TMP431. It supports two external 86temperature sensors. 87 88TMP461 is compatible with TMP401. It supports offset correction 89that is applied to the remote sensor. 90 91* Sensor offset values are temperature values 92 93 Exported via sysfs attribute tempX_offset 94
