Kernel driver dps920ab
========================

Supported chips:

  * Delta DPS920AB

    Prefix: 'dps920ab'

    Addresses scanned: -

Authors:
    Robert Marko <robert.marko@sartura.hr>


Description
-----------

This driver implements support for Delta DPS920AB 920W 54V DC single output
power supply with PMBus support.

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.

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.
