Currently, ACPI does not support the use of a nargs_prop (e.g., associated with a reference in fwnode_property_get_reference_args(). Instead, ACPI expects the number of arguments (nargs) to be explicitly passed or known. This behavior diverges from Open Firmware (OF), which allows the use of a #*-cells property in the referenced node to determine the number of arguments. Since fwnode_property_get_reference_args() is a common interface used across both OF and ACPI firmware paradigms, it is desirable to have a unified calling convention that works seamlessly for both. Add the support for ACPI to parse a nargs_prop from the referenced fwnode, aligning its behavior with the OF backend. This allows drivers and subsystems using fwnode_property_get_reference_args() to work in a firmware-agnostic way without having to hardcode or special-case argument counts for ACPI.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
