  27. Description
  28. -----------
  29. This driver supports hardware montoring for National Semiconductor / TI LM25056,
  30. LM25066, LM5064, and LM5064 Power Management, Monitoring, Control, and
  31. Protection ICs.
  32. The driver is a client driver to the core PMBus driver. Please see
  33. Documentation/hwmon/pmbus for details on PMBus client drivers.
  34. Usage Notes
  35. -----------
  36. This driver does not auto-detect devices. You will have to instantiate the
  37. devices explicitly. Please see Documentation/i2c/instantiating-devices for
  38. details.
  39. Platform data support
  40. ---------------------
  41. The driver supports standard PMBus driver platform data.
  42. Sysfs entries
