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

Usage Notes
|
|
-----------
|
|
|
|
This driver does not auto-detect devices. You will have to instantiate the
|
|
devices explicitly. Please see Documentation/i2c/instantiating-devices for
|
|
details.

|
|
attributes are read-only.
|
|
|
|
in[1-4]_label "vout[1-4]"
|
|
in[1-4]_input Measured voltage. From READ_VOUT register.

|
|
in[1-4]_max Maximum voltage. From VOUT_OV_WARN_LIMIT register.
|
|
in[1-4]_lcrit Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register.
|
|
in[1-4]_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
|
|
in[1-4]_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status.
|
|
in[1-4]_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status.
|
|
in[1-4]_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
|
|
in[1-4]_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
|
|
in[1-4]_highest Historical maximum voltage.
|
|
in[1-4]_reset_history Write any value to reset history.
|
|
|
|
temp1_input Measured temperature. From READ_TEMPERATURE_1 register.

|
READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
|
|
status is set.
|
|
temp1_crit_alarm Chip temperature critical high alarm. Set by comparing
|
|
READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
|
|
status is set.
|
|
temp1_highest Historical maximum temperature.
|
|
