| 36 | Description | |
| 37 | ----------- | |
| 38 | ||
| 92417dad | 39 | This driver supports hardware monitoring for National Semiconductor / TI LM25056, |
| 666c1490 | 40 | LM25066, LM5064, and LM5066/LM5066I Power Management, Monitoring, |
| 5783ec2e | 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. | |
