Here's what you need in your .config to use SoundWire on x86-based
hardware. Today this includes mostly Dell platforms, HP x360 convertible
laptops and Intel 'bishop canyon' NUC laptops.
CONFIG_REGMAP_SOUNDWIRE=m
CONFIG_REGMAP_SOUNDWIRE_MBQ=m
CONFIG_SND_INTEL_SOUNDWIRE_ACPI=m
CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH=m
CONFIG_SND_SOC_SOF_INTEL_SOUNDWIRE_LINK_BASELINE=m
CONFIG_SND_SOC_SOF_INTEL_SOUNDWIRE=m
CONFIG_SOUNDWIRE=m
CONFIG_SOUNDWIRE_CADENCE=m
CONFIG_SOUNDWIRE_INTEL=m
# CONFIG_SOUNDWIRE_QCOM is not set
CONFIG_SOUNDWIRE_GENERIC_ALLOCATION=m
I think you can get everything if you select these 3 high-level ones:
CONFIG_SOUNDWIRE
CONFIG_SND_SOC_SOF_INTEL_SOUNDWIRE
CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH
