13	Description
14	-----------
16	The LM95245 is an 11-bit digital temperature sensor with a 2-wire System
17	Management Bus (SMBus) interface and TruTherm technology that can monitor
18	the temperature of a remote diode as well as its own temperature.
19	The LM95245 can be used to very accurately monitor the temperature of
20	external devices such as microprocessors.
22	All temperature values are given in millidegrees Celsius. Local temperature
23	is given within a range of -127 to +127.875 degrees. Remote temperatures are
24	given within a range of -127 to +255 degrees. Resolution depends on
25	temperature input and range.
27	Each sensor has its own critical limit. Additionally, there is a relative
28	hysteresis value common to both critical limits. To make life easier to
29	user-space applications, two absolute values are exported, one for each
30	channel, but these values are of course linked. Only the local hysteresis
31	can be set from user-space, and the same delta applies to the remote
32	hysteresis.
34	The lm95245 driver can change its update interval to a fixed set of values.
35	It will round up to the next selectable interval. See the datasheet for exact
36	values. Reading sensor values more often will do no harm, but will return
37	'old' values.
