17	Description
18	-----------
19	
20	LM95235 and LM95245 are 11-bit digital temperature sensors with a 2-wire System
21	Management Bus (SMBus) interface and TruTherm technology that can monitor
22	the temperature of a remote diode as well as its own temperature.
23	The chips can be used to very accurately monitor the temperature of
24	external devices such as microprocessors.
25	
26	All temperature values are given in millidegrees Celsius. Local temperature
27	is given within a range of -127 to +127.875 degrees. Remote temperatures are
28	given within a range of -127 to +255 degrees. Resolution depends on
29	temperature input and range.
30	
31	Each sensor has its own critical limit. Additionally, there is a relative
32	hysteresis value common to both critical limits. To make life easier to
33	user-space applications, two absolute values are exported, one for each
34	channel, but these values are of course linked. Only the local hysteresis
35	can be set from user-space, and the same delta applies to the remote
36	hysteresis.
37	
38	The lm95245 driver can change its update interval to a fixed set of values.
39	It will round up to the next selectable interval. See the datasheet for exact
40	values. Reading sensor values more often will do no harm, but will return
41	'old' values.
