SSICR has SWSP bit (= Serial WS Polarity) which decides WS pin 1st channel polarity (low or hi). This bit shouldn't exchange after running. Current SSI "parent" doesn't care SSICR, just controls clock only. Because of this behavior, if platform uses SSI0 as playback, SSI1 as capture, and if user starts capture -> playback order, SSI0 SSICR::SWSP bit exchanged 0 -> 1 during captureing, and it makes capture noise. This patch cares SSICR on SSI parent, too.

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.
