| 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. |
