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 for
|
|
details.
|
|
|
|
|
|
Platform data support
|
|
---------------------
|
|
|
|
The driver supports standard PMBus driver platform data.

======================= ========================================================
|
|
in1_label "vout1"

|
|
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.
