Description¶
This driver supports hardware monitoring for National Semiconductor / TI LM25056,LM25066, LM5064, and LM5066/LM5066I Power Management, Monitoring,Control, and Protection ICs.
The driver is a client driver to the core PMBus driver. Please seeDocumentation/hwmon/pmbus.rst for details on PMBus client drivers.
Usage Notes¶
This driver does not auto-detect devices. You will have to instantiate thedevices explicitly. Please see Documentation/i2c/instantiating-devices.rst fordetails.
Platform data support¶
The driver supports standard PMBus driver platform data.
