| 41 | Description | |
| 42 | ----------- | |
| 43 | ||
| 92417dad | 44 | This driver supports hardware monitoring for National Semiconductor / TI LM25056, |
| 5783ec2e XW |
45 | LM25063, LM25066, LM5064, and LM5066/LM5066I Power Management, Monitoring, |
| 46 | Control, and Protection ICs. | |
| 03e9bd8d GR |
47 | |
| 48 | The driver is a client driver to the core PMBus driver. Please see | |
| 49 | Documentation/hwmon/pmbus for details on PMBus client drivers. | |
| 50 | ||
| 51 | ||
| 52 | Usage Notes | |
| 53 | ----------- | |
| 54 | ||
| 55 | This driver does not auto-detect devices. You will have to instantiate the | |
| 56 | devices explicitly. Please see Documentation/i2c/instantiating-devices for | |
| 57 | details. | |
| 58 | ||
| 59 | ||
| 60 | Platform data support | |
| 61 | --------------------- | |
| 62 | ||
| 63 | The driver supports standard PMBus driver platform data. | |
