Some jacks integrated on devices with this codec, such as certain Apple Silicon Macs, have quite trigger-happy tip sense switches that cause a tip sense IRQ before the plug is fully seated. If users are unfortunate with their timing, this can lead to headsets being detected as mic-less headphones among other issues with the codec's device detection routines. Introduce some rudimentary ring sense interrupt handling so that we can re-trigger the codec's detection routines when we are certain that the plug is fully seated. This seems to differ from what other Cirrus drivers do, but is necessary for devices to be reliably detected properly here.

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.
