Please see72Documentation/hwmon/pmbus.rst for details on PMBus client drivers.73 74 75Usage Notes76-----------77 78This driver does not auto-detect devices. You will have to instantiate the79devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for80details.81 82The shunt (sense) resistor value can be configured by a device tree property;83see Documentation/devicetree/bindings/hwmon/pmbus/ti,lm25066.yaml for details.84 85Platform data support86---------------------87 88The driver supports standard PMBus driver platform data.89 90 91Sysfs entries92-------------93 94The following attributes are supported.
