Different generations of Intel hardware rely on different programming sequences to enable SoundWire IP. In existing hardware, the SoundWire interrupt is enabled with a register field in the DSP register space. With HDaudio multi-link extensions registers, the SoundWire interrupt will be enabled with a generic interrupt enable field in LCTL, without any dependency on the DSP being enabled. Add a per-chip callback following the example of the check_sdw_irq() model already upstream. Note that the callback is not populated yet for MeteorLake (MTL) since the interrupts are already enabled in the init. A follow-up patch will move the functionality to this callback after a couple of cleanups.

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.
