mb/google/volteer: Add SoundWire codecs to volteer variant
Enable drivers for SoundWire codecs and define the topology in the devicetree for the volteer variant with the SoundWire daughter board connected. +------------------+ +-------------------+ | | | Headphone Codec | | Intel Tigerlake | +--->| Realtek ALC5682 | | SoundWire | | | ID 1 | | Controller | | +-------------------+ | | | | Link 0 +----+ +-------------------+ | | | Left Speaker Amp | | Link 1 +----+--->| Maxim MAX98373 | | | | | ID 3 | | Link 2 | | +-------------------+ | | | | Link 3 | | +-------------------+ | | | | Right Speaker Amp | +------------------+ +--->| Maxim MAX98373 | | ID 7 | +-------------------+ This was tested by booting the firmware and dumping the SSDT table to ensure that all SoundWire ACPI devices are created as expected with the properties that are defined in coreboot under \_SB.PCI0: HDAS - Intel Tigerlake HDA PCI device HDAS.SNDW - Intel Tigerlake SoundWire Controller HDAS.SNDW.SW01 - Realtek ALC5682 - Headphone Codec HDAS.SNDW.SW13 - Maxim MAX98373 - Left Speaker Amp HDAS.SNDW.SW17 - Maxim MAX98373 - Right Speaker Amp BUG=b:146482091 Signed-off-by: Duncan Laurie <dlaurie@google.com> Change-Id: I7782059807416369e0e1ba0d4d7c79dcab0fcbc5 Reviewed-on: https://review.coreboot.org/c/coreboot/+/40894 Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
