TMP464 provides one local and four remote +sensors. TMP468 provides one local and eight remote sensors. +Temperature is measured in degrees Celsius. The chips are wired over +I2C/SMBus and specified over a temperature range of -40 to +125 degrees +Celsius. Resolution for both the local and remote channels is 0.0625 +degree C. + +The chips support only temperature measurements. The driver exports +temperature values, limits, and alarms via the following sysfs files: + +**temp[1-9]_input** + +**temp[1-9]_max** + +**temp[1-9]_max_hyst** + +**temp[1-9]_max_alarm** + +**temp[1-9]_crit** + +**temp[1-9]_crit_alarm** + +**temp[1-9]_crit_hyst** + +**temp[2-9]_offset** + +**temp[2-9]_fault** + +Each sensor can be individually disabled via Devicetree or from sysfs +via: + +**temp[1-9]_enable** + +If labels were specified in Devicetree, additional sysfs files will +be present: + +**temp[1-9]_label** + +The update interval is configurable with the following sysfs attribute. + +**update_interval** -- cgit v1.2.3
