[PATCH v2 0/4] ASoC: simple-card-utils: create jack inputs for aux_devs
by Astrid Rost 24 Jan '23

24 Jan '23

Add a generic way to create jack inputs for auxiliary jack detection drivers (e.g. via i2c, spi), which are not part of any real codec. The simple-card can be used as combining card driver to add the jacks, no new one is required. Create a jack (for input-events) for jack devices in the auxiliary device list (aux_devs). A device which returns a valid value on get_jack_type counts as jack device; set_jack is required to add the jack to the device. v1 -> v2: Auxiliary jack drivers return the correct snd_jack_type with the function: get_jack_type. - No devicetree changes in simple-card. - soc-component: changed name to: get_jack_type. - simple-jack-utils: updated algorithm to add jack devices. A device which returns a valid value on get_jack_type counts as jack device - ts3a227e: added devicetree property jack-type, added NULL check for jack.

[PATCH 1/2] soundwire: bus: Don't filter slave alerts
by Charles Keepax 23 Jan '23

23 Jan '23

Currently the SoundWire core will loop handling slave alerts but it will only handle those present when the alert was first raised. This causes some issues with the Cadence SoundWire IP, which only generates an IRQ when alert changes state. This means that if a new alert arrives whilst old alerts are being handled it will not be handled in the currently loop and then no further alerts will be processed since alert never changes state to trigger a new IRQ. Correct this issue by allowing the core to handle all pending alerts in the IRQ handling loop. The code will still only loop up to SDW_READ_INTR_CLEAR_RETRY times, so it shouldn't be possible for it get completely stuck and if you are generating IRQs faster than you can handle them you likely have bigger problems anyway.

[PATCH] ASoC: Intel: avs: Simplify probe-component implementation

There is no need for the probe-component to be part of the PCM component list as it does not make use of ASoC-topology and does not participate in creating any PCM streams.

[PATCH v2 0/8] ASoC: cs42l42: Add Soundwire support
by Stefan Binding 23 Jan '23

23 Jan '23

The CS42L42 has a Soundwire interface for control and audio. This chain of patches adds support for this. Patches #1 .. #5 split out various changes to the existing code that are needed for adding Soundwire. These are mostly around clocking and supporting the separate probe and enumeration stages in Soundwire. Patches #6 .. #8 actually adds the Soundwire handling. Changes since v1: - fixes for various review comments from v1 - add support for wakeup from clock stop using hardware interrupts - use port_prep callback to prepare/deprepare codec Richard Fitzgerald (6): ASoC: cs42l42: Add SOFT_RESET_REBOOT register ASoC: cs42l42: Ensure MCLKint is a multiple of the sample rate ASoC: cs42l42: Separate ASP config from PLL config ASoC: cs42l42: Export some functions for Soundwire ASoC: cs42l42: Add Soundwire support ASoC: cs42l42: Don't set idle_bias_on Stefan Binding (2): soundwire: stream: Add specific prep/deprep commands to port_prep callback ASoC: cs42l42: Wait for debounce interval after resume drivers/soundwire/stream.c | 4 +- include/linux/soundwire/sdw.h | 8 +- include/sound/cs42l42.h | 5 + sound/soc/codecs/Kconfig | 8 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/cs42l42-sdw.c | 603 +++++++++++++++++++++++++++++++++ sound/soc/codecs/cs42l42.c | 127 ++++--- sound/soc/codecs/cs42l42.h | 9 +- 8 files changed, 716 insertions(+), 50 deletions(-) create mode 100644 sound/soc/codecs/cs42l42-sdw.c -- 2.34.1

Question about DPCM private_data of soc-compress.c
by Kuninori Morimoto 23 Jan '23

23 Jan '23

Hi ALSA ML I'm not familiar with soc-compress.c, but I think dpcm_capture case don't need "else" ? I think it is same as soc-pcm.c :: soc_new_pcm(). I'm happy to post patch if someone acknowledge this question. --- soc-compress.c -------- int snd_soc_new_compress(...) { ... if (rtd->dai_link->dynamic) { ... if (rtd->dai_link->dpcm_playback) be_pcm->streams[SNDRV_PCM_STREAM_PLAYBACK].substream->private_data = rtd; - else if (rtd->dai_link->dpcm_capture) + if (rtd->dai_link->dpcm_capture) be_pcm->streams[SNDRV_PCM_STREAM_CAPTURE].substream->private_data = rtd; ... } ... } --- soc-pcm.c --------------- int soc_new_pcm(...) { ... if (rtd->dai_link->no_pcm || rtd->dai_link->params) { if (playback) pcm->streams[SNDRV_PCM_STREAM_PLAYBACK].substream->private_data = rtd; => if (capture) pcm->streams[SNDRV_PCM_STREAM_CAPTURE].substream->private_data = rtd; goto out; } ... } Thank you for your help !! Best regards --- Kuninori Morimoto

[PATCH v2 0/3] Add the Renesas IDT821034 codec support
by Herve Codina 23 Jan '23

23 Jan '23

Hi, The Renesas IDT821034 codec is four channel PCM codec with on-chip filters and programmable gain setting. It also provides SLIC (Subscriber Line Interface Circuit) signals as GPIOs. Based on previous iteration: https://lore.kernel.org/all/20230111134905.248305-1-herve.codina@bootlin.co… the bigger change is the codec driver rework in order to remove the regmap virtual registers layer. Best regards, Herve Codina Changes v1 -> v2: - All patches Reformat commit log - Patch 1 Remove '$ref: /schemas/gpio/gpio.yaml#' Use 'unevaluatedProperties: false' Update the node name and remove the sound node in the example - Patch 2 Change the file header comment format Rework in order to remove the regmap virtual registers Herve Codina (3): dt-bindings: sound: Add Renesas IDT821034 codec ASoC: codecs: Add support for the Renesas IDT821034 codec MAINTAINERS: add the Renesas IDT821034 codec entry .../bindings/sound/renesas,idt821034.yaml | 75 ++ MAINTAINERS | 7 + sound/soc/codecs/Kconfig | 12 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/idt821034.c | 1200 +++++++++++++++++ 5 files changed, 1296 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/renesas,idt821034.yaml create mode 100644 sound/soc/codecs/idt821034.c -- 2.39.0
