By default, the I2S ports are configured in master mode during DSP powerup sequences, the FS and BCLK lines will be driven on startup, even when the topology file explicitly requires the SSP to be slave. This may be problematic for external components configured in master mode who don't expect the Intel SOC/PCH to drive. Fix by configuring the SSP as slave before the SSP outputs are enabled to avoid this transient behavior. When the topology file configures the SSP as clock master, the initial slave configuration will be overridden.

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.
