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 see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
This driver does not auto-detect devices. You will have to instantiate the devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for details.
The shunt (sense) resistor value can be configured by a device tree property; see Documentation/devicetree/bindings/hwmon/pmbus/ti,lm25066.yaml for details.
The driver supports standard PMBus driver platform data.
The following attributes are supported. Limits are read-write; all other attributes are read-only.
