 | Description | 
 | ----------- | 
 |  | 
 | This driver supports hardware monitoring for below power supply devices | 
 | which support PMBus Protocol: | 
 |  | 
 |   * BEL PFE1100 | 
 |  | 
 |     1100 Watt AC to DC power-factor-corrected (PFC) power supply. | 
 |     PMBus Communication Manual is not publicly available. | 
 |  | 
 |   * BEL PFE3000 | 
 |  | 
 |     3000 Watt AC/DC power-factor-corrected (PFC) and DC-DC power supply. | 
 |     PMBus Communication Manual is not publicly available. | 
 |  | 
 | The driver is a client driver to the core PMBus driver. Please see | 
 | Documentation/hwmon/pmbus.rst for details on PMBus client drivers. | 
 |  | 
 |  | 
 | Usage Notes | 
 | ----------- | 
 |  | 
 | This driver does not auto-detect devices. You will have to instantiate the | 
 | devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for | 
 | details. | 
 |  | 
 | Example: the following will load the driver for an PFE3000 at address 0x20 | 
 | on I2C bus #1:: | 
 |  | 
 | 	$ modprobe bel-pfe | 
 | 	$ echo pfe3000 0x20 > /sys/bus/i2c/devices/i2c-1/new_device | 
 |  | 
 |  | 
 | Platform data support | 
 | --------------------- | 
 |  | 
 | The driver supports standard PMBus driver platform data. |
