Public bug reported:
Add non-sof soundwire support to AMD platforms
[ Impact ]
This patch series introduce non-sof soundwire support for AMD platform,
as well as code reorganization in preparation for that.
[ Test ]
1. Install the test kernel
2. Install proper alsa-ucm-confs
3. Confirm the audio function normally on the DUT with 1) AMD soundwire and 2)
existing Intel platforms using soundwire. Might include:
* Checkbox audio test plan
* Built-in speaker and built-in mic
* Audio function when headphone is connected to the DUT.
[ Where problems could occur ]
Patches needed, other than 3 SAUCE patches that planned to upstream in
6.13 cycle, are listed in [1] to [8] below.
Soundwire used to appear mostly on Intel platforms and is almost always
in combination with sof. To support AMD, it has to be refactored into a
more generic framework (or at least that's what AMD people did). This
happens in patch series [1][2] and [3], extracting soundwire code from
the sound/soc/intel directory to a more generic location, as well as
rename/refactor things to better fit the ASoC context. This will impact
all other soundwire platforms and if not done correctly, regression risk
may be high.
The all other patch sets other than [5] are AMD specific, so
theoretically the impact is limited to AMD platforms with soundwire,
which are rather uncommon.
