  43 Description
  44 -----------
  45
  46 This driver implements support for Maxim MAX20710, MAX20730, MAX20734, and MAX20743
  47 Integrated, Step-Down Switching Regulators with PMBus support.
  48
  49 The driver is a client driver to the core PMBus driver.
  50 Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.

  53 Usage Notes
  54 -----------
  55
  56 This driver does not auto-detect devices. You will have to instantiate the
  57 devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
  58 details.
