  22. Description
  23. -----------
  24. This driver supports the MAX16508 VR13 Dual-Output Voltage Regulator
  25. as well as the MAX16600, MAX16601, and MAX16602 VR13.HC Dual-Output
  26. Voltage Regulator chipsets.
  27. The driver is a client driver to the core PMBus driver.
  28. Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
  29. Usage Notes
  30. -----------
  31. This driver does not auto-detect devices. You will have to instantiate the
  32. devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
  33. details.
  34. Platform data support
  35. ---------------------
  36. The driver supports standard PMBus driver platform data.
  37. Sysfs entries
