Current pinmux group for audio in/out assumes 4ch I2S case but the UniPhier AIO hardware also supports 1ch and 2ch I2S. So divide current ain1 group into ain1, ain1_dat2 and ain1_dat4 groups. Divide other ain and aout in the same way.

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.
