| 25 | Description |
| 26 | ----------- |
| 27 | |
| 28 | This driver supports hardware montoring for National Semiconductor LM25066, |
| 29 | LM5064, and LM5064 Power Management, Monitoring, Control, and Protection ICs. |
| 30 | |
| 31 | The driver is a client driver to the core PMBus driver. Please see |
| 32 | Documentation/hwmon/pmbus for details on PMBus client drivers. |
| 33 | |
| 34 | |
| 35 | Usage Notes |
| 36 | ----------- |
| 37 | |
| 38 | This driver does not auto-detect devices. You will have to instantiate the |
| 39 | devices explicitly. Please see Documentation/i2c/instantiating-devices for |
| 40 | details. |
| 41 | |
| 42 | |
| 43 | Platform data support |
| 44 | --------------------- |
| 45 | |
| 46 | The driver supports standard PMBus driver platform data. |
