2023-11-29ASoC: qcom: Add helper for allocating Soundwire stream runtimeKrzysztof Kozlowski
Newer Qualcomm SoC soundcards will need to allocate Soundwire stream runtime in their startup op. The code will be exactly the same for all soundcards, so add a helper for that.

2023-01-09ASoC: qcom: Fix building APQ8016 machine driver without SOUNDWIREStephan Gerhold
Older Qualcomm platforms like APQ8016 do not have hardware support for SoundWire, so kernel configurations made specifically for those platforms will usually not have CONFIG_SOUNDWIRE enabled. Unfortunately commit 8d89cf6ff229 ("ASoC: qcom: cleanup and fix dependency of QCOM_COMMON") breaks those kernel configurations, because SOUNDWIRE is now a required dependency for SND_SOC_QCOM_COMMON (and in turn also SND_SOC_APQ8016_SBC). Trying to migrate such a kernel config silently disables SND_SOC_APQ8016_SBC and breaks audio functionality. The soundwire helpers in common.c are only used by two of the Qualcomm audio machine drivers, so building and requiring CONFIG_SOUNDWIRE for all platforms is unnecessary. There is no need to stuff all common code into a single module. Fix the issue by moving the soundwire helpers to a separate SND_SOC_QCOM_SDW module/option that is selected only by the machine drivers that make use of them. This also allows reverting the imply/depends changes from the previous fix because both SM8250 and SC8280XP already depend on SOUNDWIRE, so the soundwire helpers will be only built if SOUNDWIRE is really enabled.
