[PATCH 0/7] ASoC: qcom: Use qcom_snd_parse_of() for apq8016_sbc
At the moment we have two separate functions to parse the sound card properties from the device tree: qcom_snd_parse_of() for DPCM and apq8016_sbc_parse_of() without DPCM. These functions are almost identical except for a few minor differences.
This patch set extends qcom_snd_parse_of() to handle links without DPCM, so that we can use one common function for all (qcom) machine drivers.

Simplify the machine drivers for newer SoCs a bit by using the devm_* function calls that automatically release the resources when the driver is removed or when probing fails.

Commit a2120089251f ("ASoC: qcom: common: set correct directions for dailinks") introduced a call to q6afe_is_rx_port() to set the dpcm_playback/capture parameters correctly. This is necessary because those parameters are now validated to match the capabilities of the DAIs. [1]
The disadvantage of introducing the call to q6afe_is_rx_port() is that it makes the qcom_snd_parse_of() helper dependent on the QDSP6 driver. When the ADSP is bypassed (e.g. in apq8016-sbc) QDSP6 is not used.
There is a generic solution for this now: The correct direction for the links is already defined by the DAI capabilities (e.g. rx ports only support playback).
Commit 25612477d20b ("ASoC: soc-dai: set dai_link dpcm_ flags with a helper") introduced the snd_soc_dai_link_set_capabilities() function that we can use to set dpcm_playback/dpcm_capture according to the capabilities of the DAIs.
Use that for both FE/BE DAI links to avoid the dependency on the QDSP6 driver.

This reverts commit 4a95737440d ("ASoc: q6afe: add support to get port direction"), since the function is not needed anymore.
q6afe-dai already exposes the possible directions for a DAI through the DAI capabilities (playback/capture-only DAI). Now we use snd_soc_dai_link_set_capabilities() to infer the information directly from the DAI capabilities.

So far qcom_snd_parse_of() was only used to parse the device tree for boards using the QDSP6 driver together with DPCM. apq8016_sbc uses an almost identical version (apq8016_sbc_parse_of()) which parses links without DPCM.
Given the similarity of the two functions it is useful to combine these two. To allow using qcom_snd_parse_of() in apq8016_sbc we need to support parsing links without DPCM as well.
This is pretty simple: A DPCM link in the device tree is defined using:
- DPCM frontend: "cpu" - DPCM backend: "cpu", "platform" and "codec"
... while a link without DPCM has "cpu" and "codec" (but no "platform").
Add a few more if conditions to handle links without DPCM correctly.

The apq8016_sbc device tree binding uses a "qcom," vendor prefix for all device tree properties, while qcom_snd_parse_of() uses the same properties without a prefix.
In the future it would be nice to make this consistent, however, for backwards compatibility we need to parse both names to allow apq8016_sbc to use the common qcom_snd_parse_of() function.

Now that we have updated qcom_snd_parse_of() to handle the device tree bindings used for apq8016_sbc, update the apq8016_sbc driver to use the common function and remove the duplicated code.

qcom_snd_parse_of() tends to produce lots of error messages during bootup:
MultiMedia1: error getting cpu dai name
This happens because the DAIs are not probed until the ADSP remoteproc has booted, which takes a while. Until it is ready, snd_soc_of_get_dai_name() returns -EDEFER_PROBE to retry probing later. This is perfectly normal, so cleanup the kernel log a bit by not printing in case of -EPROBE_DEFER.

At the moment we have two separate functions to parse the sound card properties from the device tree: qcom_snd_parse_of() for DPCM and apq8016_sbc_parse_of() without DPCM. These functions are almost identical except for a few minor differences.
This patch set extends qcom_snd_parse_of() to handle links without DPCM, so that we can use one common function for all (qcom) machine drivers.

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
