| 43 | Description | |
| 44 | ----------- | |
| 45 | ||
| 66102281 | 46 | This driver supports the MAX16508 VR13 Dual-Output Voltage Regulator |
| a6f7c5d0 GR |
47 | as well as the MAX16600, MAX16601, and MAX16602 VR13.HC Dual-Output |
| 48 | Voltage Regulator chipsets. | |
| 2138f885 GR |
49 | |
| 50 | The driver is a client driver to the core PMBus driver. | |
| 51 | Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. | |
| 52 | ||
| 53 | ||
| 54 | Usage Notes | |
| 55 | ----------- | |
| 56 | ||
| 57 | This driver does not auto-detect devices. You will have to instantiate the | |
| 58 | devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for | |
| 59 | details. | |
| 60 | ||
| 61 | ||
| 62 | Platform data support | |
| 63 | --------------------- | |
| 64 | ||
| 65 | The driver supports standard PMBus driver platform data. | |
| 66 | ||
