13Description
14-----------
15
16This driver supports hardware montoring for Maxim MAX16064 Quad Power-Supply
17Controller with Active-Voltage Output Control and PMBus Interface.
18
19The driver is a client driver to the core PMBus driver.
20Please see Documentation/hwmon/pmbus for details on PMBus client drivers.

23Usage Notes
24-----------
25
26This driver does not auto-detect devices. You will have to instantiate the
27devices explicitly. Please see Documentation/i2c/instantiating-devices for
28details.

40The following attributes are supported. Limits are read-write; all other
41attributes are read-only.
42
43in[1-4]_label "vout[1-4]"
44in[1-4]_input Measured voltage. From READ_VOUT register.
45in[1-4]_min Minumum Voltage. From VOUT_UV_WARN_LIMIT register.
46in[1-4]_max Maximum voltage. From VOUT_OV_WARN_LIMIT register.
47in[1-4]_lcrit Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register.
48in[1-4]_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
49in[1-4]_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status.
50in[1-4]_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status.
51in[1-4]_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
52in[1-4]_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
53
54temp1_input Measured temperature. From READ_TEMPERATURE_1 register.
55temp1_max Maximum temperature. From OT_WARN_LIMIT register.
56temp1_crit Critical high temperature. From OT_FAULT_LIMIT register.
57temp1_max_alarm Chip temperature high alarm. Set by comparing
58 READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
59 status is set.
60temp1_crit_alarm Chip temperature critical high alarm. Set by comparing
61 READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
62 status is set.
