| Description |
| ----------- |
| |
| This driver supports hardware montoring for National Semiconductor LM25066, |
| LM5064, and LM5064 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. |
| |
| |
