13	Description
14	-----------
15	
16	LM95234 is an 11-bit digital temperature sensor with a 2-wire System Management
17	Bus (SMBus) interface and TrueTherm technology that can very accurately monitor
18	the temperature of four remote diodes as well as its own temperature.
19	The four remote diodes can be external devices such as microprocessors,
20	graphics processors or diode-connected 2N3904s. The LM95234's TruTherm
21	beta compensation technology allows sensing of 90 nm or 65 nm process
22	thermal diodes accurately.
23	
24	All temperature values are given in millidegrees Celsius. Temperature
25	is provided within a range of -127 to +255 degrees (+127.875 degrees for
26	the internal sensor). Resolution depends on temperature input and range.
27	
28	Each sensor has its own maximum limit, but the hysteresis is common to all
29	channels. The hysteresis is configurable with the tem1_max_hyst attribute and
30	affects the hysteresis on all channels. The first two external sensors also
31	have a critical limit.
32	
33	The lm95234 driver can change its update interval to a fixed set of values.
34	It will round up to the next selectable interval. See the datasheet for exact
35	values. Reading sensor values more often will do no harm, but will return
36	'old' values.
