Description |
|
----------- |
|
|
|
This driver supports hardware monitoring 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.rst 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.rst for |
|
details. |
|

|
|
Platform data support |
|
--------------------- |
|
|
|
The driver supports standard PMBus driver platform data. |
|
|
|
|
|
Sysfs entries |
|
------------- |
|
|
|
The following attributes are supported. Limits are read-write; all other |
|
attributes are read-only. |
|
|
|
======================= ======================================================== |
|
in[1-4]_label "vout[1-4]" |
|
in[1-4]_input Measured voltage. From READ_VOUT register. |
|
in[1-4]_min Minimum Voltage. From VOUT_UV_WARN_LIMIT register. |
|
in[1-4]_max Maximum voltage. From VOUT_OV_WARN_LIMIT register. |
|
in[1-4]_lcrit Critical minimum 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. |
|
temp1_max Maximum temperature. From OT_WARN_LIMIT register. |
|
temp1_crit Critical high temperature. From OT_FAULT_LIMIT register. |
|
temp1_max_alarm Chip temperature high alarm. Set by comparing |
|
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. |
|
temp1_reset_history Write any value to reset history. |
