21	Description
22	-----------
23	
24	This driver implements support for Texas Instruments TMP421, TMP422
25	and TMP423 temperature sensor chips. These chips implement one local
26	and up to one (TMP421), up to two (TMP422) or up to three (TMP423)
27	remote sensors. Temperature is measured in degrees Celsius. The chips
28	are wired over I2C/SMBus and specified over a temperature range of -40
29	to +125 degrees Celsius. Resolution for both the local and remote
30	channels is 0.0625 degree C.
31	
32	The chips support only temperature measurement. The driver exports
33	the temperature values via the following sysfs files:
34	
35	temp[1-4]_input
36	temp[2-4]_fault
