Description |
|
----------- |
|
|
|
This driver supports hardware monitoring for Maxim MAX8688 Digital Power-Supply |
|
Controller/Monitor with 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. |
|

|
|
|
The following attributes are supported. Limits are read-write; all other |
|
attributes are read-only. |
|
|
|
======================= ======================================================== |
|
in1_label "vout1" |
|
in1_input Measured voltage. From READ_VOUT register. |
|
in1_min Minimum Voltage. From VOUT_UV_WARN_LIMIT register. |
|
in1_max Maximum voltage. From VOUT_OV_WARN_LIMIT register. |
|
in1_lcrit Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register. |
|
in1_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT |
|

|
status. |
|
in1_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT |
|
status. |
|
in1_highest Historical maximum voltage. |
|
in1_reset_history Write any value to reset history. |
|
|
|
curr1_label "iout1" |
|
curr1_input Measured current. From READ_IOUT register. |
|
curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register. |
