Description¶
This driver implements support for Maxim MAX20710, MAX20730, MAX20734, and MAX20743 Integrated, Step-Down Switching Regulators with PMBus support.
The driver is a client driver to the core PMBus driver. Please see Kernel driver pmbus 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.
