19 -----------
20
21 This driver implements support for the Maxim M
22 chips.
23
24 The three devices are very similar, but the MA
25 set; only two remote temperature inputs vs the
26 two ICs.
27
28 The driver is able to distinguish between the
29 entries as follows:

31 - MAX1805, MAX1668 and MAX1989:
32
33 =============== == ===========================
34 temp1_input ro local (ambient) temperature
35 temp1_max rw local temperature maximum t
36 temp1_max_alarm ro local temperature maximum t
37 temp1_min rw local temperature minimum t
38 temp1_min_alarm ro local temperature minimum t
39 temp2_input ro remote temperature 1
40 temp2_max rw remote temperature 1 maximu
41 temp2_max_alarm ro remote temperature 1 maximu
42 temp2_min rw remote temperature 1 minimu
43 temp2_min_alarm ro remote temperature 1 minimu
44 temp3_input ro remote temperature 2
45 temp3_max rw remote temperature 2 maximu
46 temp3_max_alarm ro remote temperature 2 maximu
47 temp3_min rw remote temperature 2 minimu
48 temp3_min_alarm ro remote temperature 2 minimu
49 =============== == ===========================
