Current dai_link related property are parsed and enabled only on CPU
port node (A)(b)(c). OTOH, Audio Graph Card2 supports many connections
like Multi-CPU, DPCM, Codec2Codec today. For example in Multi-CPU case,
it will be checked via (X) -> (B) -> (b) process, but (X) / (B) part
property is not parsed.
>From dai_link related settings point of view, (B) (C) part and Codec
port also enabled is more viscerally understandable, and useful.
card2 {
(X) links = <&snd-cpu (A)
&snd-multi (B)
&snd-dpcm (C)
...>
multi {
ports {
(B) snd-multi: port { ... };
...
};
};
dpcm {
ports {
(C) snd-dpcm: port { ... };
...
};
};
codec2codec {
...
};
};
cpu_device {
ports {
(A) snd-cpu: port { ... };
(b) mcpu: port { ... };
(c) dcpu: port { ... };
}
};
One note here is that if it was Multi-CPU/Codec case, 1st port only
enabled to have property it.

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.
