17Description
18-----------
19
20This driver supports hardware monitoring for Maxim MAX16064 Quad Power-Supply
21Controller with Active-Voltage Output Control and PMBus Interface.
22
23The driver is a client driver to the core PMBus driver.
24Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.

27Usage Notes
28-----------
29
30This driver does not auto-detect devices. You will have to instantiate the
31devices explicitly. Please see Documentation/i2c/instantiating-devices for
32details.

44The following attributes are supported. Limits are read-write; all other
45attributes are read-only.
46
47======================= ========================================================
48in[1-4]_label		"vout[1-4]"
49in[1-4]_input		Measured voltage. From READ_VOUT register.
50in[1-4]_min		Minimum Voltage. From VOUT_UV_WARN_LIMIT register.
51in[1-4]_max		Maximum voltage. From VOUT_OV_WARN_LIMIT register.
52in[1-4]_lcrit		Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register.
53in[1-4]_crit		Critical maximum voltage. From VOUT_OV_FAULT_LIMIT
54			register.
55in[1-4]_min_alarm	Voltage low alarm. From VOLTAGE_UV_WARNING status.
56in[1-4]_max_alarm	Voltage high alarm. From VOLTAGE_OV_WARNING status.
57in[1-4]_lcrit_alarm	Voltage critical low alarm. From VOLTAGE_UV_FAULT
58			status.
59in[1-4]_crit_alarm	Voltage critical high alarm. From VOLTAGE_OV_FAULT
60			status.
61in[1-4]_highest		Historical maximum voltage.
62in[1-4]_reset_history	Write any value to reset history.
63
64temp1_input		Measured temperature. From READ_TEMPERATURE_1 register.
65temp1_max		Maximum temperature. From OT_WARN_LIMIT register.
66temp1_crit		Critical high temperature. From OT_FAULT_LIMIT register.
67temp1_max_alarm		Chip temperature high alarm. Set by comparing
68			READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
69			status is set.
70temp1_crit_alarm	Chip temperature critical high alarm. Set by comparing
71			READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
72			status is set.
73temp1_highest		Historical maximum temperature.
74temp1_reset_history	Write any value to reset history.
