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.
