| Description | |
| ----------- | |
| This driver supports hardware montoring for National Semiconductor / TI LM25056, | |
| LM25063, LM25066, LM5064, and LM5066 Power Management, Monitoring, Control, and | |
| Protection ICs. | |
| The driver is a client driver to the core PMBus driver. Please see | |
| Documentation/hwmon/pmbus for details on PMBus client drivers. | |
| Usage Notes | |
| ----------- | |
| This driver does not auto-detect devices. You will have to instantiate the | |
| devices explicitly. Please see Documentation/i2c/instantiating-devices for | |
| details. | |
| Platform data support | |
| --------------------- | |
| The driver supports standard PMBus driver platform data. | |
