  32. Description
  33. -----------
  34. This driver supports hardware montoring for National Semiconductor / TI LM25056,
  35. LM25063, LM25066, LM5064, and LM5066 Power Management, Monitoring, Control, and
  36. Protection ICs.
  37. The driver is a client driver to the core PMBus driver. Please see
  38. Documentation/hwmon/pmbus for details on PMBus client drivers.
  39. Usage Notes
  40. -----------
  41. This driver does not auto-detect devices. You will have to instantiate the
  42. devices explicitly. Please see Documentation/i2c/instantiating-devices for
  43. details.
  44. Platform data support
  45. ---------------------
  46. The driver supports standard PMBus driver platform data.
  47. Sysfs entries
