  13. Description
  14. -----------
  15. This driver supports hardware monitoring for below power supply devices
  16. which support PMBus Protocol:
  17. * BEL PFE1100
  18. 1100 Watt AC to DC power-factor-corrected (PFC) power supply.
  19. PMBus Communication Manual is not publicly available.
  20. * BEL PFE3000
  21. 3000 Watt AC/DC power-factor-corrected (PFC) and DC-DC power supply.
  22. PMBus Communication Manual is not publicly available.
  23. The driver is a client driver to the core PMBus driver. Please see
  24. Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
  25. Usage Notes
  26. -----------
  27. This driver does not auto-detect devices. You will have to instantiate the
  28. devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
  29. details.
  30. Example: the following will load the driver for an PFE3000 at address 0x20
  31. on I2C bus #1::
  32. $ modprobe bel-pfe
  33. $ echo pfe3000 0x20 > /sys/bus/i2c/devices/i2c-1/new_device
  34. Platform data support
  35. ---------------------
  36. The driver supports standard PMBus driver platform data.
