This patch exports I2Sx_IOE to allow user to config mclk
direction from DT.
e.g.
i2s2 mclk as output:
&ext_codec {
clocks = <&cru I2S2_MCLKOUT>;
clock-names = "mclk";
assigned-clocks = <&cru I2S2_MCLK_IOE>, <&cru I2S2_MCLKOUT>;
assigned-clock-rates = <0>, <12288000>;
assigned-clock-parents = <&cru I2S2_MCLKOUT>;
};

i2s2 mclk as input:

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
