Introduce a new 'of-fullname-regex' property that takes a regular
expression and matches against the OF_FULLNAME property. It allows
matching controllers that don't have a unique DT address across sibling
controllers, and thus dt-mmio can't be used.
One particular example of where this is needed is on MT8195 which has
multiple USB controllers described by two level deep nodes and using the
ranges property:
ssusb2: usb@112a1000 {
reg = <0 0x112a1000 0 0x2dff>, <0 0x112a3e00 0 0x0100>;
ranges = <0 0 0 0x112a0000 0 0x3f00>;
xhci2: usb@0 {

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.
