Description
|
|
-----------
|
|
|
|
This driver supports hardware monitoring for Maxim MAX15301 controller chip and
|
|
compatible modules.
|
|
|
|
The driver is a client driver to the core PMBus driver. Please see
|
|
Documentation/hwmon/pmbus.rst and Documentation.hwmon/pmbus-core 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.
|
|
|
|
|
|
Module parameters
|
|
-----------------
|
|
|
|
delay
|
|
-----
|
|
|
|
The controller requires a minimum interval between I2C bus accesses.
|
|
The default interval is set to 100 us. For manual override, the driver
|
|
provides a writeable module parameter, 'delay', which can be used to
|
|
set the interval to a value between 0 and 65,535 microseconds.
|
|
|
|
|
|
