18 | Description | |
19 | ----------- | |
20 | ||
21 | This driver implements support for Delta DPS920AB 920W 54V DC single output | |
22 | power supply with PMBus support. | |
23 | ||
24 | The driver is a client driver to the core PMBus driver. | |
25 | Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. | |
