Despite minimal datasheet differences, the driver seems
perfectly compatible with CMM-4030D-261.
Tested CMM-4030D-261 to work with this changes:
/ {
cmm4030d: cmm4030d {
#sound-dai-cells = <0>;
compatible = "cui,cmm-4030d-261";
};
sound_mic {
compatible = "simple-audio-card";
simple-audio-card,name = "i2s mem mic";
simple-audio-card,format = "i2s";
simple-audio-card,bitclock-master = <&sound_master>;
simple-audio-card,frame-master = <&sound_master>;
sound_master: simple-audio-card,cpu {
sound-dai = <&ssi2>;
system-clock-frequency = <2822400>;
};
simple-audio-card,codec {
sound-dai = <&cmm4030d>;
};
};
};

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.
