Kernel driver inspur-ipsps1¶
Supported chips:
Inspur Power System power supply unit
Author: John Wang <wangzqbj@inspur.com>
Description¶
This driver supports Inspur Power System power supplies. This driver is a client to the core PMBus driver.
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.
