26	Description
27	-----------
28	
29	This driver implements support for Texas Instruments TMP401, TMP411,
30	TMP431, and TMP432 chips. These chips implement one or two remote and
31	one local temperature sensors. Temperature is measured in degrees
32	Celsius. Resolution of the remote sensor is 0.0625 degree. Local
33	sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not
34	supported by the driver so far, so using the default resolution of 0.5
35	degree).
36	
37	The driver provides the common sysfs-interface for temperatures (see
38	Documentation/hwmon/sysfs-interface under Temperatures).
39	
40	The TMP411 and TMP431 chips are compatible with TMP401. TMP411 provides
41	some additional features.
42	
43	* Minimum and Maximum temperature measured since power-on, chip-reset
44	
45	  Exported via sysfs attributes tempX_lowest and tempX_highest.
46	
47	* Reset of historical minimum/maximum temperature measurements
48	
49	  Exported via sysfs attribute temp_reset_history. Writing 1 to this
50	  file triggers a reset.
51	
52	TMP432 is compatible with TMP401 and TMP431. It supports two external
53	temperature sensors.
