Parse the /aliases node to assign any fixed bus numbers, as is done with
the i2c subsystem. Numbering for non-aliased busses will start after the
highest fixed bus number.
This allows an alias node such as:
aliases {
i3c0 = &bus_a,
i3c4 = &bus_b,
};
to set the numbering for a set of i3c controllers:
/* fixed-numbered bus, assigned "i3c-0" */
bus_a: i3c-master {
};
/* another fixed-numbered bus, assigned "i3c-4" */
bus_b: i3c-master {
};
/* dynamic-numbered bus, likely assigned "i3c-5" */
bus_c: i3c-master {
};
If no i3c device aliases are present, the numbering will stay as-is,
starting from 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 Restructured Text 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.
