Description¶
This driver supports the MAX16508 VR13 Dual-Output Voltage Regulator as well as the MAX16601 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.
