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.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
