dtc generates the following warning when building the LAN966x devicetree
overlay (lan966x_pci.dtso):
Warning (interrupts_property): /fragment@0/__overlay__/pci-ep-bus@0/oic@e00c0120: Missing interrupt-parent
The oic interrupt parent is the PCI device itself. The PCI device node
is the node on which the dtbo will be applied and this node already has
properties needed.
In order to remove the warning, add the missing properties in the
overlay fragment node. Properties in this node will not be added when
the overlay is applied (which is what we expect) but makes dtc happy.

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.
