Merge series "ASoC: dt-bindings: Rework audio-graph-port schema" from Rob Herring <robh@kernel.org>: This series refactors the audio-graph-port.yaml schema moving the 'port' node out of the schema and updating to use graph.yaml schema.

Because soc_free_pcm_runtime(rtd) checks rtd pointer and freeing rtd->xxx, it doesn't work correctly in case of rtd allocation failed. We need to use device_unregister(dev) in such case. This patch fixup it. Signed-off-by:

We don't need to mind freeing for rtd, because it was created from devm_kzalloc(dev, xxx) which is rtd->dev. This means, if rtd->dev was freed, rtd will be also freed automatically. soc_new_pcm_runtime(...) { ... rtd = devm_kzalloc(dev, ...); rtd->dev = dev; ... } This explanation was missing at soc_free_pcm_runtime() comment. This patch indicates it. Signed-off-by: -

Merge tag 'mute-led-rework' of https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound into asoc-5.13 ALSA: control - add generic LED API This patchset tries to resolve the diversity in the audio LED control among the ALSA drivers. A new control layer registration is introduced which allows to run additional operations on top of the elementary ALSA sound controls. A new control access group (three bits in the access flags) was introduced to carry the LED group information for the sound controls. The low-level sound drivers can just mark those controls using this access group. This information is not exported to the user space, but user space can manage the LED sound control associations through sysfs (last patch) per Mark's request. It makes things fully configurable in the kernel and user space (UCM). The actual state ('route') evaluation is really easy (the minimal value check for all channels / controls / cards). If there's more complicated logic for a given hardware, the card driver may eventually export a new read-only sound control for the LED group and do the logic itself. The new LED trigger control code is completely separated and possibly optional (there's no symbol dependency). The full code separation allows eventually to move this LED trigger control to the user space in future. Actually it replaces the already present functionality in the kernel space (HDA drivers) and allows a quick adoption for the recent hardware (ASoC codecs including SoundWire). snd_ctl_led 24576 0 The sound driver implementation is really easy: 1) call snd_ctl_led_request() when control LED layer should be automatically activated / it calls module_request("snd-ctl-led") on demand / 2) mark all related kcontrols with SNDRV_CTL_ELEM_ACCESS_SPK_LED or SNDRV_CTL_ELEM_ACCESS_MIC_LED Link: https://lore.kernel.org/r/20210317172945.842280-1-perex@perex.czSigned-off-by:

Merge series "ASoC: simple-card: cleanup and prepare for Multi CPU/Codec support" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>: Hi Mark I want to add new audio-graph-card2 driver which can support not only DPCM, but also Multi-CPU/Codec, and Codec2Codec. And it is also supporting user customization. But before supporting such driver, we need to cleanup existing simple-card / audio-graph, because these and new driver are sharing code. This patch-set are cleanup and prepare for Multi-CPU/Codec support.

The SoC sound core will generate a driver name by normalizing the card name. However, most of the time that name does not tell anything about the driver and is therefore useless for this purpose. Make the driver name more useful by setting it explicitly during card initialization. Signed-off-by:

The Chuwi Hi8 tablet is using an analog mic on IN1 and has its jack-detect connected to JD2_IN4N, instead of using the default IN3 for its internal mic and JD1_IN4P for jack-detect. It also only has 1 speaker. Add a quirk applying the correct settings for this configuration. Signed-off-by:

simple-card checks DT links 2 times. 1st is for counting DAIs / links to allocating memory, 2nd is for detecting DAIs. To detecting DAIs as CPU-dummy -> dummy-Codec order when DPCM case, it uses loops 2 times. Because of this kind of complex background, it needs to use local varuable for it, and each call-back functions need to care about it. Now, 1st and 2nd DT link check are using same order, thus we can share same code. This patch do it. Signed-off-by:

To detecting DAIs as CPU-dummy -> dummy-Codec order when DPCM case, it uses loops 2 times at 2nd DT link check. But it doesn't do it at 1st DT link check. for (li.cpu = 1; li.cpu >= 0; li.cpu--) { /* * Detect all CPU first, and Detect all Codec 2n * * In Normal sound case, all DAIs are detected * as "CPU-Codec". * * In DPCM sound case, * all CPUs are detected as "CPU-dummy", and * all Codecs are detected as "dummy-Codec". * To avoid random sub-device numbering, * detect "dummy-Codec" in last; */ ret = simple_for_each_link(...); ... } To prepare supporting multi-CPU/Codec, and code cleanup, this patch use same loop for 1st DT link check, too.
