zl3073x devlink support
=======================

This document describes the devlink features implemented by the ``zl3073x``
device driver.

Parameters
==========

   :widths: 5 5 90

   * - Name
     - Mode
     - Notes
   * - ``clock_id``
     - driverinit
     - Set the clock ID that is used by the driver for registering DPLL devices
       and pins.

Info versions
=============

The ``zl3073x`` driver reports the following versions

    * - ``custom_cfg``
      - running
      - 1.3.0.1
      - Device configuration version customized by OEM

Flash Update
============

The ``zl3073x`` driver implements support for flash update using the
``devlink-flash`` interface. It supports updating the device flash using a
combined flash image ("bundle") that contains multiple components (firmware
parts and configurations).

During the flash procedure, the standard firmware interface is not available,
so the driver unregisters all DPLLs and associated pins, and re-registers them
once the flash procedure is complete.

The driver does not support any overwrite mask flags.

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.
