20 This driver supports hardware montoring for Analog Devices ADM1275 and ADM1276
21 Hot-Swap Controller and Digital Power Monitor.
23 ADM1275 and ADM1276 are hot-swap controllers that allow a circuit board to be
24 removed from or inserted into a live backplane. They also feature current and
25 voltage readback via an integrated 12-bit analog-to-digital converter (ADC),
26 accessed using a PMBus interface.
28 The driver is a client driver to the core PMBus driver. Please see
29 Documentation/hwmon/pmbus for details on PMBus client drivers.
35 This driver does not auto-detect devices. You will have to instantiate the
36 devices explicitly. Please see Documentation/i2c/instantiating-devices for
43 The driver supports standard PMBus driver platform data. Please see
44 Documentation/hwmon/pmbus for details.
50 The following attributes are supported. Limits are read-write, history reset
51 attributes are write-only, all other attributes are read-only.
53 in1_label "vin1" or "vout1" depending on chip variant and
55 in1_input Measured voltage.
56 in1_min Minumum Voltage.
57 in1_max Maximum voltage.
58 in1_min_alarm Voltage low alarm.
59 in1_max_alarm Voltage high alarm.
60 in1_highest Historical maximum voltage.
61 in1_reset_history Write any value to reset history.
64 curr1_input Measured current.
65 curr1_max Maximum current.
66 curr1_max_alarm Current high alarm.
67 curr1_lcrit Critical minimum current. Depending on the chip
68 configuration, either curr1_lcrit or curr1_crit is
69 supported, but not both.
70 curr1_lcrit_alarm Critical current low alarm.
71 curr1_crit Critical maximum current. Depending on the chip
72 configuration, either curr1_lcrit or curr1_crit is
73 supported, but not both.
74 curr1_crit_alarm Critical current high alarm.
75 curr1_highest Historical maximum current.
76 curr1_reset_history Write any value to reset history.
