This describes the interface for the ADT7475 driver:
2
+
3
+
(there are 4 fans, numbered fan1 to fan4):
4
+
5
+
fanX_input Read the current speed of the fan (in RPMs)
6
+
fanX_min Read/write the minimum speed of the fan. Dropping
7
+
below this sets an alarm.
8
+
9
+
(there are three PWMs, numbered pwm1 to pwm3):
10
+
11
+
pwmX Read/write the current duty cycle of the PWM. Writes
12
+
only have effect when auto mode is turned off (see
13
+
below). Range is 0 - 255.
14
+
15
+
pwmX_enable Fan speed control method:
16
+
17
+
0 - No control (fan at full speed)
18
+
1 - Manual fan speed control (using pwm[1-*])
19
+
2 - Automatic fan speed control
20
+
21
+
pwmX_auto_channels_temp Select which channels affect this PWM
22
+
23
+
1 - TEMP1 controls PWM
24
+
2 - TEMP2 controls PWM
25
+
4 - TEMP3 controls PWM
26
+
6 - TEMP2 and TEMP3 control PWM
27
+
7 - All three inputs control PWM
28
+
29
+
pwmX_freq Read/write the PWM frequency in Hz. The number
30
+
should be one of the following:
31
+
32
+
11 Hz
33
+
14 Hz
34
+
22 Hz
35
+
29 Hz
36
+
35 Hz
37
+
44 Hz
38
+
58 Hz
39
+
88 Hz
40
+
41
+
pwmX_auto_point1_pwm Read/write the minimum PWM duty cycle in automatic mode
42
+
43
+
pwmX_auto_point2_pwm Read/write the maximum PWM duty cycle in automatic mode
44
+
45
+
(there are three temperature settings numbered temp1 to temp3):
46
+
47
+
tempX_input Read the current temperature. The value is in milli
48
+
degrees of Celsius.
49
+
50
+
tempX_max Read/write the upper temperature limit - exceeding this
51
+
will cause an alarm.
52
+
53
+
tempX_min Read/write the lower temperature limit - exceeding this
54
+
will cause an alarm.
55
+
56
+
tempX_offset Read/write the temperature adjustment offset
57
+
58
+
tempX_crit Read/write the THERM limit for remote1.
59
+
60
+
tempX_crit_hyst Set the temperature value below crit where the
61
+
fans will stay on - this helps drive the temperature
62
+
low enough so it doesn't stay near the edge and
63
+
cause THERM to keep tripping.
64
+
65
+
tempX_auto_point1_temp Read/write the minimum temperature where the fans will
66
+
turn on in automatic mode.
67
+
68
+
tempX_auto_point2_temp Read/write the maximum temperature over which the fans
69
+
will run in automatic mode. tempX_auto_point1_temp
70
+
and tempX_auto_point2_temp together define the
71
+
range of automatic control.
72
+
73
+
tempX_alarm Read a 1 if the max/min alarm is set
74
+
tempX_fault Read a 1 if either temp1 or temp3 diode has a fault
75
+
76
+
(There are two voltage settings, in1 and in2):
77
+
78
+
inX_input Read the current voltage on VCC. Value is in
79
+
millivolts.
80
+
81
+
inX_min read/write the minimum voltage limit.
82
+
Dropping below this causes an alarm.
83
+
84
+
inX_max read/write the maximum voltage limit.
85
+
Exceeding this causes an alarm.
86
+
87
+
inX_alarm Read a 1 if the max/min alarm is set.
