  Integrated, Step-Down Switching Regulators with PMBus support.
  
  The driver is a client driver to the core PMBus driver.
  Please see Documentation/hwmon/pmbus.rst 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.rst for
  details.
