| 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. | |
| 26 | ||
| 27 | ||
| 28 | Usage Notes | |
| 29 | ----------- | |
| 30 | ||
| 31 | This driver does not auto-detect devices. You will have to instantiate the | |
| 32 | devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for | |
| 33 | details. | |
