There are certain use cases where these are needed independent of the platform, e.g. to control an analog switch or mux connected to speaker or headphone outputs. I agree that it is cleaner to move the IO muxing to a new schema though. Perhaps we could define something like a shared qcom,sndcard-common.yaml schema to avoid duplication for these generic properties? In the Linux driver, these are handled for all platforms in sound/soc/qcom/common.c. Thanks, Stephan

In the Linux > driver, these are handled for all platforms in sound/soc/qcom/common.c. This was added to the common driver code but it does not mean it is reasonable binding. I don't understand why for example we even accept here aux-devs, instead of putting them into one of DAI links. The pin-switches and widgets could be used, but are they? The only valid argument to keep them is that you added them to common driver code. Best regards, Krzysztof

[1/1] ASoC: dt-bindings: qcom,apq8016-sbc-sndcard: move to separate binding commit: 8716bd241fa120aacce5e0136125b7ecc74fe3b2 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark

It is typically the case (e.g. an analog speaker amplifier connected in parallel to the headphone output of one of the codecs), but I don't think we can assume that as a general rule. There are often multiple DAI links that go to one codec and then it might be tricky to decide which of the DAI links the aux-dev belongs to. > The pin-switches and widgets could be used, but are they? The only valid > argument to keep them is that you added them to common driver code. These go hand in hand with the aux-devs property. If you have multiple analog audio components connected to a codec output (e.g. an analog speaker amplifier connected to the codec headphone output) then the pin-switches/widgets describe that the output paths (speaker and headphones) should be separately controllable. The alternative for pin-switches and widgets in the DT is to hardcode them in the ASoC board/machine driver with a separate board-specific compatible. Personally, I would prefer to keep the machine driver specific to the SoC instead of having definitions for each and every board. Thanks, Stephan

Right, aux devices may cover more than one DAI link (eg, if there's a CODEC that can do mixing and they're connected to an analog output) or may in rare cases not fit with one at all (there's use cases where you have a sound card that has no DAIs and is all analog bypass). > > The pin-switches and widgets could be used, but are they?

Plus the above cases where you don't have a direct mapping with aux devs and DAIs also apply to pin switches since they're in the analog domain.

The APQ8016 SBC and MSM8916 QDSP6 sound cards are a bit different from others: they have additional IO muxing address space and pin control. Move them to separate schema, so the original qcom,sm8250.yaml will be easier to manage. New schema is going to grow for other platforms having more of IO muxing address spaces.
