| 19 | Description | |
| 20 | ----------- | |
| 21 | ||
| 22 | This driver supports the MAX16601 VR13.HC Dual-Output Voltage Regulator | |
| 23 | Chipset. | |
| 24 | ||
| 25 | The driver is a client driver to the core PMBus driver. | |
| 26 | Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. | |
| 27 | ||
| 28 | ||
| 29 | Usage Notes | |
| 30 | ----------- | |
| 31 | ||
| 32 | This driver does not auto-detect devices. You will have to instantiate the | |
| 33 | devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for | |
| 34 | details. | |
| 35 | ||
| 36 | ||
| 37 | Platform data support | |
| 38 | --------------------- | |
| 39 | ||
| 40 | The driver supports standard PMBus driver platform data. | |
| 41 | ||
