ASoC: SOF: Intel: use hdev->info.link_mask directly

2026-02-03T13:47:11+00:00

The link_mask variable is not changed after setting to
hdev->info.link_mask until it is used for another purpose to get the
used SoundWire links and set to mach->mach_params.links. Besides, the
link_mask variable should be reset before any link id is added to the
link_mask. To fix the issue above and avoid confusing, use the
hdev->info.link_mask variable directly to check if the SoundWire link
is enabled.

For those amps that use their name as name prefix the amp id should be
added after a hyphen symbol. Like "rt1320-1".

ASoC: SOF: Intel: use sof_sdw as default SDW machine driver

2025-10-13T10:23:29+00:00

If there is no SoundWire machine matches the existing acpi match table,
get the required machine data from the acpi table and construct the
link adrs and endpoints. Pass the data to the default Intel SoundWire
machine driver. And we don't need to add new item to the acpi match
table in common cases.
We will construct a dummy topology name. The dummy topology is just
used to extract the platform name for function topology and should not
be used.

ASoC: SOF: Intel: only detect codecs when HDA DSP probe

2025-08-29T08:50:37+00:00

SDW codecs use the global HDaudio WAKEEN/STS to detect wakes since LNL.
But the wake event is handled in the SDW driver. We should only clear
WAKESTS for the HDA and IDISP codecs that was detected when HDA DSP
probe. The SoundWire codec will be included in the codec_mask if we read
the STATESTS register when a SoundWire codec wake event happens.
The commit avoid updating bus->codec_mask in resume to not clear WAKESTS
of SoundWire codecs.
