ASoC: simple-card-utils: add sysclk ordering support

2026-02-22T23:52:23+00:00

When simple-audio-card programs sysclk for CPU and codec DAIs during hw_params, the ordering of these calls may matter on some platforms. Some CPU DAIs finalize or adjust the MCLK rate as part of their set_sysclk() callback (for example by calling clk_set_rate()). If the codec sysclk is configured before the CPU DAI applies the final MCLK rate, the codec may configure its internal clocking based on a non-final MCLK value. Such situations can arise depending on the clock provider/consumer relationship between the CPU DAI and the codec. Introduce an explicit sysclk ordering enum in simple-card-utils and use it to control the order of snd_soc_dai_set_sysclk() calls in the mclk-fs handling path. The default behaviour remains unchanged (codec-first) to avoid regressions.

ASoC: simple-card-utils: use snd_soc_ret()

We can use snd_soc_ret() to indicate error message when return. Let's use it. Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/87a5b12qlg.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

Merge tag 'asoc-v6.14' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2025-01-20T15:15:07+00:00

ASoC: Updates for v6.14 This was quite a quiet release for what I imagine are holiday related reasons, the diffstat is dominated by some Cirrus Logic Kunit tests. There's the usual mix of small improvements and fixes, plus a few new drivers and features. The diffstat includes some DRM changes due to work on HDMI audio. - Allow clocking on each DAI in an audio graph card to be configured separately. - Improved power management for Renesas RZ-SSI. - KUnit testing for the Cirrus DSP framework. - Memory to meory operation support for Freescale/NXP platforms. - Support for pause operations in SOF. - Support for Allwinner suinv F1C100s, Awinc AW88083, Realtek ALC5682I-VE

ASoC: simple-card-utils: fix priv->dai_props indexing

2025-01-15T13:11:12+00:00

As of commit cb18cd26039f ("ASoC: soc-core: do rtd->id trick at snd_soc_add_pcm_runtime()") the ID stored in the PCM runtime data can no longer be safely used to index the priv->dai_props array. This is because the ID may be modified during snd_soc_add_pcm_runtime(), thus resulting in an ID that's no longer a valid array index. To fix this, use the position of the dai_link stored inside the PCM runtime data relative to the start of the dai_link array as index into the priv->dai_props array.

ASoC: simple-card-utils: add link-trigger-order support

2024-06-26T16:47:56+00:00

Some Sound Card might need special trigger ordering which is based on CPU/Codec connection. It is already supported on ASoC, but Simple Audio Card / Audio Graph Card still not support it. Let's support it. Cc: Maxim Kochetkov Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/87r0d2zojq.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: simple-card-utils: remove both playback/capture_only check

2024-06-03T14:59:33+00:00

soc-pcm.c :: soc_get_playback_capture() will indicate error if both playback_only / capture_only were true. Thus, graph_util_parse_link_direction() which setup playback_only / capture_only don't need to check it. And, its return value is not used on existing driver. Let's remove it.

ASoC: simple-card-utils: Split simple_fixup_sample_fmt func

2024-05-27T12:59:49+00:00

Split the simple_fixup_sample_fmt() into two functions by adding one more function named simple_util_get_sample_fmt() to return the sample format value. This is useful for drivers that wish to simply get the sample format without setting the mask.
