13 | Description | ||
14 | ----------- | ||
15 | |||
16 | This driver supports hardware montoring for Maxim MAX8688 Digital Power-Supply | ||
17 | Controller/Monitor with PMBus Interface. | ||
18 | |||
19 | The driver is a client driver to the core PMBus driver. Please see | ||
20 | Documentation/hwmon/pmbus for details on PMBus client drivers. | ||
21 | |||
22 | |||
23 | Usage Notes | ||
24 | ----------- | ||
25 | |||
26 | This driver does not auto-detect devices. You will have to instantiate the | ||
27 | devices explicitly. Please see Documentation/i2c/instantiating-devices for | ||
28 | details. | ||
29 | |||
30 | |||
31 | Platform data support | ||
32 | --------------------- | ||
33 | |||
34 | The driver supports standard PMBus driver platform data. | ||
35 | |||

37 | Sysfs entries | ||
38 | ------------- | ||
39 | |||
40 | The following attributes are supported. Limits are read-write; all other | ||
41 | attributes are read-only. | ||
42 | |||
43 | in1_label "vout1" | ||
44 | in1_input Measured voltage. From READ_VOUT register. | ||
45 | in1_min Minumum Voltage. From VOUT_UV_WARN_LIMIT register. | ||
46 | in1_max Maximum voltage. From VOUT_OV_WARN_LIMIT register. | ||
47 | in1_lcrit Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register. | ||
48 | in1_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register. | ||
49 | in1_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status. | ||
50 | in1_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status. | ||
51 | in1_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status. | ||
52 | in1_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status. | ||
53 | |||
54 | curr1_label "iout1" | ||
55 | curr1_input Measured current. From READ_IOUT register. | ||
56 | curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register. | ||
57 | curr1_crit Critical maximum current. From IOUT_OC_FAULT_LIMIT register. | ||
58 | curr1_max_alarm Current high alarm. From IOUT_OC_WARN_LIMIT register. | ||
59 | curr1_crit_alarm Current critical high alarm. From IOUT_OC_FAULT status. | ||

61 | temp1_input Measured temperature. From READ_TEMPERATURE_1 register. | ||
62 | temp1_max Maximum temperature. From OT_WARN_LIMIT register. | ||
63 | temp1_crit Critical high temperature. From OT_FAULT_LIMIT register. | ||
64 | temp1_max_alarm Chip temperature high alarm. Set by comparing | ||
65 | READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING | ||
66 | status is set. | ||
67 | temp1_crit_alarm Chip temperature critical high alarm. Set by comparing | ||
68 | READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT | ||
69 | status is set. | ||
