The SDCA_CASCADE bit is a SoundWire 1.2 addition. It is technically in the DP0_INT register, but SDCA interrupts shall not be handled as part of the DP0 interrupt processing. The existing code has clear comments that we don't want to touch the SDCA_CASCADE bit, but it's actually cleared due to faulty logic dating from SoundWire 1.0 In theory clearing this bit should have no effect: a cascade bit remains set while all ORed status are set, but better safe than sorry.

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 reStructuredText 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.
