- 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.
