13 | Description | ||
14 | ----------- | ||
15 | |||
16 | This driver supports hardware montoring for Analog Devices ADM1275 Hot-Swap | ||
17 | Controller and Digital Power Monitor. | ||
18 | |||
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. | ||
23 | |||
24 | The driver is a client driver to the core PMBus driver. Please see | ||
25 | Documentation/hwmon/pmbus for details on PMBus client drivers. | ||
26 | |||
27 | |||
28 | Usage Notes | ||
29 | ----------- | ||
30 | |||
31 | This driver does not auto-detect devices. You will have to instantiate the | ||
32 | devices explicitly. Please see Documentation/i2c/instantiating-devices for | ||
33 | details. | ||
34 | |||
35 | |||
36 | Platform data support | ||
37 | --------------------- | ||
38 | |||
39 | The driver supports standard PMBus driver platform data. Please see | ||
40 | Documentation/hwmon/pmbus for details. | ||
41 | |||
42 | |||
43 | Sysfs entries | ||
44 | ------------- | ||
45 | |||
46 | The following attributes are supported. Limits are read-write; all other | ||
47 | attributes are read-only. | ||
48 | |||
49 | in1_label "vin1" or "vout1" depending on chip variant and | ||
50 | configuration. | ||
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. | ||
56 | |||
57 | curr1_label "iout1" | ||
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. | ||
