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 Kernel driver pmbus 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 How to instantiate I2C devices 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.
