ASoC: fsl: imx-card: Skip sysclk reset for active DAIs in shutdown

2026-07-14T21:23:00Z

In a full-duplex setup, when one direction (playback or capture) is closed while the other is still running, imx_aif_shutdown() was unconditionally calling snd_soc_dai_set_sysclk() with rate=0 for all cpu/codec DAIs, which would disable the clock still needed by the active stream. Add snd_soc_dai_active() checks before clearing sysclk so that only truly inactive DAIs have their clocks reset.

ASoC: fsl_sai: Fix spurious BCLK on resume by clearing BYP

2026-07-13T12:41:11Z

When the BCLK divider ratio is 1:1, fsl_sai_set_bclk() enables bypass mode by setting BYP, but never clears the bit. The BYP=1 value remains in the regcache, and is restored by regcache_sync() on the next runtime resume. Since BYP=1 combined with BCD=1 immediately outputs the ungated MCLK as BCLK without waiting for BCE/TE/RE to be enabled, the clock is driven prematurely before the stream is fully configured, causing noise on some codecs. Fix this by clearing BYP and BCI in fsl_sai_hw_free() taking into account sync mode and the opposite stream's state, so that the regcache holds BYP=0 before runtime suspend and regcache_sync() on resume will not restore bypass mode prematurely.

Replace by more specific (c files)

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

ASoC: fsl_asrc_dma: fix eDMA maxburst misalignment with channel count

2026-06-25T13:56:27Z

The back-end consumes data in units of the number of channels. When the maxburst value is not evenly divisible by the channel count, the DMA transfer length does not align with the FIFO frame boundary, causing wrong data to be copied and audible noise at the end of the stream. This is specific to eDMA: eDMA only responds to DMA requests from the back-end, whereas SDMA handles requests from both the front-end and the back-end and is not affected. For eDMA, when the back-end maxburst is not evenly divisible by the channel count, align it to the nearest valid boundary: - If maxburst >= channel count, override to the channel count so each transfer corresponds to exactly one audio frame. - If maxburst < channel count, override to 1 to avoid partial-frame transfers. Retain the original maxburst for SDMA or when it already aligns with the channel count.

ASoC: use scoped OF node handling in manual cleanup paths

2026-06-12T15:12:13Z

Cássio Gabriel says: Some ASoC drivers still manually release child OF nodes when leaving child-node iteration loops early. Convert these focused cases to scoped OF node cleanup so early returns and normal loop exits keep the same node lifetime handling without explicit of_node_put() calls. - Patch 1 updates qcom_snd_parse_of() to use for_each_available_child_of_node_scoped() for link nodes and __free(device_node) for temporary cpu/platform/codec child nodes. - Patch 2 updates fsl_qmc_audio to use for_each_available_child_of_node_scoped() for DAI child-node parsing. - Patch 3 updates cygnus-ssp to use for_each_available_child_of_node_scoped() for SSP child-node parsing.

ASoC: fsl: fsl_qmc_audio: use scoped child node loop

qmc_audio_probe() manually puts the current child node before returning from the DAI parsing loop on error. Use for_each_available_child_of_node_scoped() so the current child node is released automatically on early return and normal loop exit.

ASoC: Validate written enum values in custom controls

2026-06-11T19:44:46Z

HyeongJun An says: Some custom ASoC kcontrol put() handlers use the written enum value (ucontrol->value.enumerated.item[0]) to index a table or compute a bit shift before validating that the value is within the control's enum range. An out-of-range value written from userspace is therefore consumed before it is rejected. This is the same class addressed for the Meson codecs in commit 1e001206804b ("ASoC: meson: g12a-tohdmitx: Validate written enum values") and commit 3150b70e944e ("ASoC: meson: g12a-toacodec: Validate written enum values"). Fix four more instances: - hdac_hdmi reads e->texts[item] before validation. - aiu converts the item before validating it. - fsl_audmix converts the item and uses the result before validation. - tegra210_ahub reads e->values[item] before validation.

ASoC: fsl: fsl_audmix: Validate written enum values

2026-06-11T19:44:45Z

fsl_audmix_put_mix_clk_src() and fsl_audmix_put_out_src() convert the user-provided enum item with snd_soc_enum_item_to_val() before checking whether the item is within the enum's item count. The generic snd_soc_put_enum_double() helper performs that validation, but these callbacks use the converted value first: the clock-source path tests it with BIT(), and the output-source path indexes the prms transition table with it. Reject out-of-range enum items before converting them.

ASoC: remove .debugfs_prefix from Component

2026-06-10T11:21:16Z

Kuninori Morimoto says: Basically, we are assuming to use snd_soc_register_component() (X) to register Component. It requests Component driver (A). And, current Component has .debugfs_prefix (B). Now we can set component->debugfs_prefix (B) via component_driver->debugfs_prefix (A) today. But some drivers are still trying to set it via (B). Thus, they need to use snd_soc_component_initialize() (1) / snd_soc_component_add() (2) instead of (X), because they need to access component->debugfs_prefix (B). These functions (= 1, 2) should be capsuled into soc-xxx.c, but can't because of above drivers. This patch-set removes component->debugfs_prefix (B). The functions (= 1, 2) are still not yet be capsuled. This is step1 for it, step2 will be posted after this. Link: https://patch.msgid.link/87ldcxk5wz.wl-kuninori.morimoto.gx@renesas.com
