32 This driver implements support for Texas Instruments TMP464 and TMP468
33 temperature sensor chips. TMP464 provides one local and four remote
34 sensors. TMP468 provides one local and eight remote sensors.
35 Temperature is measured in degrees Celsius. The chips are wired over
36 I2C/SMBus and specified over a temperature range of -40 to +125 degrees
37 Celsius. Resolution for both the local and remote channels is 0.0625
40 The chips support only temperature measurements. The driver exports
41 temperature values, limits, and alarms via the following sysfs files:
47 **temp[1-9]_max_hyst**
49 **temp[1-9]_max_alarm**
53 **temp[1-9]_crit_alarm**
55 **temp[1-9]_crit_hyst**
61 Each sensor can be individually disabled via Devicetree or from sysfs
66 If labels were specified in Devicetree, additional sysfs files will
71 The update interval is configurable with the following sysfs attribute.
