[PATCH 00/10] Add support for non-interleaved mode in qmc_audio
by Herve Codina 01 Jul '24

01 Jul '24

The qmc_audio driver supports only audio in interleaved mode. Non-interleaved mode can be easily supported using several QMC channel per DAI. In that case, data related to ch0 are sent to (received from) the first QMC channel, data related to ch1 use the next QMC channel and so on up to the last channel. In terms of constraints and settings, the interleaved and non-interleaved modes are slightly different. In interleaved mode: - The sample size should fit in the number of time-slots available for the QMC channel. - The number of audio channels should fit in the number of time-slots (taking into account the sample size) available for the QMC channel. In non-interleaved mode: - The number of audio channels is the number of available QMC channels. - Each QMC channel should have the same number of time-slots. - The sample size equals the number of time-slots of one QMC channel. This series add support for the non-interleaved mode in the qmc_audio driver and is composed of the following parts: - Patches 1 and 2: Fix some issues in the qmc_audio - Patches 3 to 6: Prepare qmc_audio for the non-interleaved mode - Patches 7 and 8: Extend the QMC driver API - Patches 9 and 10: The support for non-interleaved mode itself Best regards, Hervé Herve Codina (10): ASoC: fsl: fsl_qmc_audio: Check devm_kasprintf() returned value ASoC: fsl: fsl_qmc_audio: Fix issues detected by checkpatch ASoC: fsl: fsl_qmc_audio: Split channel buffer and PCM pointer handling ASoC: fsl: fsl_qmc_audio: Identify the QMC channel involved in completion routines ASoC: fsl: fsl_qmc_audio: Introduce qmc_audio_pcm_{read,write}_submit() ASoC: fsl: fsl_qmc_audio: Introduce qmc_dai_constraints_interleaved() soc: fsl: cpm1: qmc: Introduce functions to get a channel from a phandle list soc: fsl: cpm1: qmc: Introduce qmc_chan_count_phandles() dt-bindings: sound: fsl,qmc-audio: Add support for multiple QMC channels per DAI ASoC: fsl: fsl_qmc_audio: Add support for non-interleaved mode. .../bindings/sound/fsl,qmc-audio.yaml | 41 +- drivers/soc/fsl/qe/qmc.c | 32 +- include/soc/fsl/qe/qmc.h | 27 +- sound/soc/fsl/fsl_qmc_audio.c | 590 +++++++++++++----- 4 files changed, 505 insertions(+), 185 deletions(-) -- 2.45.0

[PATCH v2 0/5] ASoC: codecs: lpass-rx-macro: Few code cleanups
by Krzysztof Kozlowski 01 Jul '24

01 Jul '24

Hi, Changes in v2: - Use cleanup.h instead of devm(), therefore not adding Dmitry's review. - New patch #5. - Link to v1: https://lore.kernel.org/r/20240627-b4-qcom-audio-lpass-codec-cleanups-v1-0-… Improve a bit the Qualcomm LPASS RX macro driver and align similar parts of code with LPASS WSA macro driver for consistency. No external dependencies. Best regards, Krzysztof --- Krzysztof Kozlowski (5): ASoC: codecs: lpass-rx-macro: Simplify with cleanup.h ASoC: codecs: lpass-rx-macro: Keep static regmap_config as const ASoC: dapm: Use unsigned for number of widgets in snd_soc_dapm_new_controls() ASoC: codecs: lpass-rx-macro: Use unsigned for number of widgets ASoC: codecs: lpass-wsa-macro: Simplify with cleanup.h include/sound/soc-dapm.h | 2 +- sound/soc/codecs/lpass-rx-macro.c | 31 +++++++++++++++++++------------ sound/soc/codecs/lpass-wsa-macro.c | 22 ++++++++++------------ sound/soc/soc-dapm.c | 2 +- 4 files changed, 31 insertions(+), 26 deletions(-) --- base-commit: feca1ff0cd5ab7bc3990ec5a387d81d4dff88068 change-id: 20240627-b4-qcom-audio-lpass-codec-cleanups-27175f1d069f Best regards, -- Krzysztof Kozlowski <krzysztof.kozlowski(a)linaro.org>
