21 This driver implements support for the Maxim MAX1668, MAX1805 and MAX1989
24 The three devices are very similar, but the MAX1805 has a reduced feature
25 set; only two remote temperature inputs vs the four available on the other
28 The driver is able to distinguish between the devices and creates sysfs
31 - MAX1805, MAX1668 and MAX1989:

37 temp1_min rw local temperature minimum threshold for alarm
38 temp1_min_alarm ro local temperature minimum threshold alarm
39 temp2_input ro remote temperature 1
40 temp2_max rw remote temperature 1 maximum threshold for alarm
41 temp2_max_alarm ro remote temperature 1 maximum threshold alarm
42 temp2_min rw remote temperature 1 minimum threshold for alarm
