32 This driver supports hardware monitoring for Analog Devices ADM1075, ADM1275,
33 ADM1276, ADM1278, ADM1293, and ADM1294 Hot-Swap Controller and Digital
36 ADM1075, ADM1275, ADM1276, ADM1278, ADM1293, and ADM1294 are hot-swap
37 controllers that allow a circuit board to be removed from or inserted into
38 a live backplane. They also feature current and voltage readback via an
39 integrated 12 bit analog-to-digital converter (ADC), accessed using a
42 The driver is a client driver to the core PMBus driver. Please see
43 Documentation/hwmon/pmbus for details on PMBus client drivers.
49 This driver does not auto-detect devices. You will have to instantiate the
50 devices explicitly. Please see Documentation/i2c/instantiating-devices for
53 The ADM1075, unlike many other PMBus devices, does not support internal voltage
54 or current scaling. Reported voltages, currents, and power are raw measurements,
55 and will typically have to be scaled.
61 The driver supports standard PMBus driver platform data. Please see
62 Documentation/hwmon/pmbus for details.
68 The following attributes are supported. Limits are read-write, history reset
69 attributes are write-only, all other attributes are read-only.
71 inX_label "vin1" or "vout1" depending on chip variant and
72 configuration. On ADM1075, ADM1293, and ADM1294,
73 vout1 reports the voltage on the VAUX pin.
74 inX_input Measured voltage.
75 inX_min Minimum Voltage.
76 inX_max Maximum voltage.
77 inX_min_alarm Voltage low alarm.
78 inX_max_alarm Voltage high alarm.
79 inX_highest Historical maximum voltage.
80 inX_reset_history Write any value to reset history.
83 curr1_input Measured current.
84 curr1_max Maximum current.
85 curr1_max_alarm Current high alarm.
86 curr1_lcrit Critical minimum current. Depending on the chip
87 configuration, either curr1_lcrit or curr1_crit is
88 supported, but not both.
89 curr1_lcrit_alarm Critical current low alarm.
90 curr1_crit Critical maximum current. Depending on the chip
91 configuration, either curr1_lcrit or curr1_crit is
92 supported, but not both.
93 curr1_crit_alarm Critical current high alarm.
94 curr1_highest Historical maximum current.
95 curr1_reset_history Write any value to reset history.
98 power1_input Input power.
99 power1_input_lowest Lowest observed input power. ADM1293 and ADM1294 only.
100 power1_input_highest Highest observed input power.
101 power1_reset_history Write any value to reset history.
103 Power attributes are supported on ADM1075, ADM1276,
104 ADM1293, and ADM1294.
106 temp1_input Chip temperature.
107 Temperature attributes are only available on ADM1278.
108 temp1_max Maximum chip temperature.
109 temp1_max_alarm Temperature alarm.
110 temp1_crit Critical chip temperature.
111 temp1_crit_alarm Critical temperature high alarm.
112 temp1_highest Highest observed temperature.
113 temp1_reset_history Write any value to reset history.
115 Temperature attributes are supported on ADM1278.
