21 This driver supports hardware montoring for Maxim MAX34440 PMBus 6-Channel
22 Power-Supply Manager and MAX34441 PMBus 5-Channel Power-Supply Manager
23 and Intelligent Fan Controller.
25 The driver is a client driver to the core PMBus driver. Please see
26 Documentation/hwmon/pmbus for details on PMBus client drivers.
32 This driver does not auto-detect devices. You will have to instantiate the
33 devices explicitly. Please see Documentation/i2c/instantiating-devices for
40 The driver supports standard PMBus driver platform data.
46 The following attributes are supported. Limits are read-write; all other
47 attributes are read-only.
49 in[1-6]_label "vout[1-6]".
50 in[1-6]_input Measured voltage. From READ_VOUT register.
51 in[1-6]_min Minumum Voltage. From VOUT_UV_WARN_LIMIT register.
52 in[1-6]_max Maximum voltage. From VOUT_OV_WARN_LIMIT register.
53 in[1-6]_lcrit Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register.
54 in[1-6]_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
55 in[1-6]_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status.
56 in[1-6]_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status.
57 in[1-6]_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
58 in[1-6]_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
59 in[1-6]_highest Historical maximum voltage.
60 in[1-6]_reset_history Write any value to reset history.
62 curr[1-6]_label "iout[1-6]".
63 curr[1-6]_input Measured current. From READ_IOUT register.
64 curr[1-6]_max Maximum current. From IOUT_OC_WARN_LIMIT register.
65 curr[1-6]_crit Critical maximum current. From IOUT_OC_FAULT_LIMIT register.
66 curr[1-6]_max_alarm Current high alarm. From IOUT_OC_WARNING status.
67 curr[1-6]_crit_alarm Current critical high alarm. From IOUT_OC_FAULT status.
68 curr[1-6]_highest Historical maximum current.
69 curr[1-6]_reset_history Write any value to reset history.
71 in6 and curr6 attributes only exist for MAX34440.
73 temp[1-8]_input Measured temperatures. From READ_TEMPERATURE_1 register.
74 temp1 is the chip's internal temperature. temp2..temp5
75 are remote I2C temperature sensors. For MAX34441, temp6
76 is a remote thermal-diode sensor. For MAX34440, temp6..8
77 are remote I2C temperature sensors.
78 temp[1-8]_max Maximum temperature. From OT_WARN_LIMIT register.
79 temp[1-8]_crit Critical high temperature. From OT_FAULT_LIMIT register.
80 temp[1-8]_max_alarm Temperature high alarm.
81 temp[1-8]_crit_alarm Temperature critical high alarm.
82 temp[1-8]_highest Historical maximum temperature.
83 temp[1-8]_reset_history Write any value to reset history.
85 temp7 and temp8 attributes only exist for MAX34440.
