| 36 | Description |
| 37 | ----------- |
| 38 | |
| 39 | This driver supports hardware monitoring for National Semiconductor / TI LM25056, |
| 40 | LM25066, LM5064, and LM5066/LM5066I Power Management, Monitoring, |
| 41 | Control, and Protection ICs. |
| 42 | |
| 43 | The driver is a client driver to the core PMBus driver. Please see |
| 44 | Documentation/hwmon/pmbus for details on PMBus client drivers. |
| 45 | |
| 46 | |
| 47 | Usage Notes |
| 48 | ----------- |
| 49 | |
| 50 | This driver does not auto-detect devices. You will have to instantiate the |
| 51 | devices explicitly. Please see Documentation/i2c/instantiating-devices for |
| 52 | details. |
| 53 | |
| 54 | |
| 55 | Platform data support |
| 56 | --------------------- |
| 57 | |
| 58 | The driver supports standard PMBus driver platform data. |
| 59 | |
| 60 | |
