17	Description
18	-----------
19	
20	LM95233 and LM95234 are 11-bit digital temperature sensors with a 2-wire
21	System Management Bus (SMBus) interface and TrueTherm technology
22	that can very accurately monitor the temperature of two (LM95233)
23	or four (LM95234) remote diodes as well as its own temperature.
24	The remote diodes can be external devices such as microprocessors,
25	graphics processors or diode-connected 2N3904s. The chip's TruTherm
26	beta compensation technology allows sensing of 90 nm or 65 nm process
27	thermal diodes accurately.
28	
29	All temperature values are given in millidegrees Celsius. Temperature
30	is provided within a range of -127 to +255 degrees (+127.875 degrees for
31	the internal sensor). Resolution depends on temperature input and range.
32	
33	Each sensor has its own maximum limit, but the hysteresis is common to all
34	channels. The hysteresis is configurable with the tem1_max_hyst attribute and
35	affects the hysteresis on all channels. The first two external sensors also
36	have a critical limit.
37	
38	The lm95234 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.
