16 This driver implements support for the Maxim MAX1668, MAX1805 and MAX1989
19 The three devices are very similar, but the MAX1805 has a reduced feature
20 set; only two remote temperature inputs vs the four available on the other
23 The driver is able to distinguish between the devices and creates sysfs
26 MAX1805, MAX1668 and MAX1989:
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
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
60 Set to non-zero if you wish to prevent write access to alarm thresholds.
