  22. Description
  23. -----------
  24. This driver implements support for Maxim MAX20710, MAX20730, MAX20734, and MAX20743
  25. Integrated, Step-Down Switching Regulators with PMBus support.
  26. The driver is a client driver to the core PMBus driver.
  27. Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
  28. Usage Notes
  29. -----------
  30. This driver does not auto-detect devices. You will have to instantiate the
  31. devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
  32. details.
