Kernel driver d1u74t
====================

Supported chips:

  * Murata D1U74T

    Prefix: 'd1u74t'

    Addresses scanned: -

    Datasheet: Publicly available at the Murata website

Authors:
    Abdurrahman Hussain <abdurrahman@nexthop.ai>


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

This driver implements support for Murata D1U74T 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.
