The current interfaces between ASoC and SoundWire are limited by the platform_device infrastructure to an init() and exit() (mapped to the platform driver.probe and .remove) To help with the platform detection, machine driver selection and management of power dependencies between DSP and SoundWire IP, the ASoC side requires: a) an ACPI scan helper, to report if any devices are exposed in the DSDT tables, and if any links are disabled by the BIOS. b) a probe helper that allocates the resources without actually starting the bus. c) a startup helper which does start the bus when all power dependencies are settled. d) an exit helper to free all resources e) an interrupt_enable/disable helper, typically invoked after the startup helper but also used in suspend routines. This patch moves all required interfaces to sdw_intel.h, mainly to allow SoundWire and ASoC parts to be merged separately once the header files are shared between trees. To avoid compilation issues, the conflicts in intel_init.c are blindly removed. This would in theory prevent the code from working, but since there are no users of the Intel Soundwire driver this has no impact. Functionality will be restored when the removal of platform devices is complete. Support for SoundWire + SOF builds will only be provided once all the required pieces are upstream.

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.
