16 This driver supports hardware montoring for Maxim MAX8688 Digital Power-Supply
17 Controller/Monitor with PMBus Interface.
19 The driver is a client driver to the core PMBus driver. Please see
20 Documentation/hwmon/pmbus for details on PMBus client drivers.
26 This driver does not auto-detect devices. You will have to instantiate the
27 devices explicitly. Please see Documentation/i2c/instantiating-devices for
34 The driver supports standard PMBus driver platform data.
40 The following attributes are supported. Limits are read-write; all other
41 attributes are read-only.
44 in1_input Measured voltage. From READ_VOUT register.
45 in1_min Minimum Voltage. From VOUT_UV_WARN_LIMIT register.
46 in1_max Maximum voltage. From VOUT_OV_WARN_LIMIT register.
47 in1_lcrit Critical minimum 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 in1_highest Historical maximum voltage.
54 in1_reset_history Write any value to reset history.
57 curr1_input Measured current. From READ_IOUT register.
58 curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register.
59 curr1_crit Critical maximum current. From IOUT_OC_FAULT_LIMIT register.
60 curr1_max_alarm Current high alarm. From IOUT_OC_WARN_LIMIT register.
61 curr1_crit_alarm Current critical high alarm. From IOUT_OC_FAULT status.
62 curr1_highest Historical maximum current.
63 curr1_reset_history Write any value to reset history.
65 temp1_input Measured temperature. From READ_TEMPERATURE_1 register.
66 temp1_max Maximum temperature. From OT_WARN_LIMIT register.
67 temp1_crit Critical high temperature. From OT_FAULT_LIMIT register.
68 temp1_max_alarm Chip temperature high alarm. Set by comparing
69 READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
71 temp1_crit_alarm Chip temperature critical high alarm. Set by comparing
72 READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
74 temp1_highest Historical maximum temperature.
75 temp1_reset_history Write any value to reset history.
