ASoC: qcom: sc7280: make use of common helpers

2025-10-29T14:54:40Z

sc7280 machine driver can make use of common sdw functions to do most of the soundwire related operations. Remove such redundant code from sc7280 driver.

ASoC: qcom: sdw: fix memory leak for sdw_stream_runtime

2025-10-29T14:54:38Z

For some reason we endedup allocating sdw_stream_runtime for every cpu dai, this has two issues. 1. we never set snd_soc_dai_set_stream for non soundwire dai, which means there is no way that we can free this, resulting in memory leak 2. startup and shutdown callbacks can be called without hw_params callback called. This combination results in memory leak because machine driver sruntime array pointer is only set in hw_params callback. Fix this by 1. adding a helper function to get sdw_runtime for substream which can be used by shutdown callback to get hold of sruntime to free. 2. only allocate sdw_runtime for soundwire dais.

ASoC: qcom: sc7280: Fix missing Soundwire runtime stream alloc

2024-10-22T20:00:38Z

Commit 15c7fab0e047 ("ASoC: qcom: Move Soundwire runtime stream alloc to soundcards") moved the allocation of Soundwire stream runtime from the Qualcomm Soundwire driver to each individual machine sound card driver, except that it forgot to update SC7280 card. Just like for other Qualcomm sound cards using Soundwire, the card driver should allocate and release the runtime. Otherwise sound playback will result in a NULL pointer dereference or other effect of uninitialized memory accesses (which was confirmed on SDM845 having similar issue).

ASoC: DT matching and header cleanups

2023-10-09T22:14:18Z

Merge series from Rob Herring : This is a series is part of ongoing clean-ups related to device matching and DT related implicit includes. Essentially of_device.h has a bunch of implicit includes and generally isn't needed any nore except for of_match_device(). As we also generally want to get rid of of_match_device() as well, I've done that so we're not updating the includes twice.

ASoC: qcom: reduce number of binding headers includes

2023-10-09T12:14:19Z

Move the includes of binding headers from Qualcomm SoC sound drivers headers to unit files actually using these bindings. This reduces the amount of work for C preprocessor and makes usage of bindings easier to follow. No impact expected on the final binaries.

ASoC: qcom: explicitly include binding headers when used

2023-10-09T12:14:18Z

Few units use qcom,lpass.h binding headers but they rely on them being included through a different header. Make the usage explicit which allows easier to find the users of a header.

ASoC: Explicitly include correct DT includes

2023-10-09T12:13:56Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
