Description

This driver supports the MAX16508 VR13 Dual-Output Voltage Regulator as well as the MAX16600, MAX16601, and MAX16602 VR13.HC Dual-Output Voltage Regulator chipsets.

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.

Platform data support

The driver supports standard PMBus driver platform data.
