| 37 | Description |
| 38 | ----------- |
| 39 | |
| 40 | This driver supports hardware monitoring for Flex PIM4328 and |
| 41 | compatible digital power interface modules. |
| 42 | |
| 43 | The driver is a client driver to the core PMBus driver. Please see |
| 44 | Documentation/hwmon/pmbus.rst and Documentation.hwmon/pmbus-core for details |
| 45 | on PMBus client drivers. |
| 46 | |
| 47 | |
| 48 | Usage Notes |
| 49 | ----------- |
| 50 | |
| 51 | This driver does not auto-detect devices. You will have to instantiate the |
| 52 | devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for |
| 53 | details. |
| 54 | |
| 55 | |
| 56 | Platform data support |
| 57 | --------------------- |
| 58 | |
| 59 | The driver supports standard PMBus driver platform data. |
| 60 | |
| 61 | |
