16 This driver supports hardware montoring for Analog Devices ADM1275 Hot-Swap
17 Controller and Digital Power Monitor.
19 The ADM1275 is a hot-swap controller that allows a circuit board to be removed
20 from or inserted into a live backplane. It also features current and voltage
21 readback via an integrated 12-bit analog-to-digital converter (ADC), accessed
22 using a PMBus. interface.
24 The driver is a client driver to the core PMBus driver. Please see
25 Documentation/hwmon/pmbus for details on PMBus client drivers.
31 This driver does not auto-detect devices. You will have to instantiate the
32 devices explicitly. Please see Documentation/i2c/instantiating-devices for
39 The driver supports standard PMBus driver platform data. Please see
40 Documentation/hwmon/pmbus for details.
46 The following attributes are supported. Limits are read-write; all other
47 attributes are read-only.
49 in1_label "vin1" or "vout1" depending on chip variant and
51 in1_input Measured voltage. From READ_VOUT register.
52 in1_min Minumum Voltage. From VOUT_UV_WARN_LIMIT register.
53 in1_max Maximum voltage. From VOUT_OV_WARN_LIMIT register.
54 in1_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status.
55 in1_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status.
58 curr1_input Measured current. From READ_IOUT register.
59 curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register.
60 curr1_max_alarm Current high alarm. From IOUT_OC_WARN_LIMIT register.
