13	Description
14	-----------
15	
16	This driver implements support for the Maxim MAX1668, MAX1805 and MAX1989
17	chips.
18	
19	The three devices are very similar, but the MAX1805 has a reduced feature
20	set; only two remote temperature inputs vs the four avaible on the other
21	two ICs.
22	
23	The driver is able to distinguish between the devices and creates sysfs
24	entries as follows:
25	
26	MAX1805, MAX1668 and MAX1989:
27	
28	temp1_input     ro local (ambient) temperature
29	temp1_max       rw local temperature maximum threshold for alarm
30	temp1_max_alarm ro local temperature maximum threshold alarm
31	temp1_min       rw local temperature minimum threshold for alarm
32	temp1_min_alarm ro local temperature minimum threshold alarm
33	temp2_input     ro remote temperature 1
34	temp2_max       rw remote temperature 1 maximum threshold for alarm
35	temp2_max_alarm ro remote temperature 1 maximum threshold alarm
36	temp2_min       rw remote temperature 1 minimum threshold for alarm
37	temp2_min_alarm ro remote temperature 1 minimum threshold alarm
38	temp3_input     ro remote temperature 2
39	temp3_max       rw remote temperature 2 maximum threshold for alarm
40	temp3_max_alarm ro remote temperature 2 maximum threshold alarm
41	temp3_min       rw remote temperature 2 minimum threshold for alarm
42	temp3_min_alarm ro remote temperature 2 minimum threshold alarm
43	
44	MAX1668 and MAX1989 only:
45	temp4_input     ro remote temperature 3
46	temp4_max       rw remote temperature 3 maximum threshold for alarm
47	temp4_max_alarm ro remote temperature 3 maximum threshold alarm
48	temp4_min       rw remote temperature 3 minimum threshold for alarm
49	temp4_min_alarm ro remote temperature 3 minimum threshold alarm
50	temp5_input     ro remote temperature 4
51	temp5_max       rw remote temperature 4 maximum threshold for alarm
52	temp5_max_alarm ro remote temperature 4 maximum threshold alarm
53	temp5_min       rw remote temperature 4 minimum threshold for alarm
54	temp5_min_alarm ro remote temperature 4 minimum threshold alarm
55	
56	Module Parameters
57	-----------------
58	
59	* read_only: int
60	  Set to non-zero if you wish to prevent write access to alarm thresholds.
