2024-07-08ASoC: fsl-asoc-card: merge spdif support from imx-spdif.cElinor Montmasson
The imx-spdif machine driver creates audio card to directly use an S/PDIF device. However, it doesn't support interacting with an ASRC. fsl-asoc-card already has the support to create audio card which can use the ASRC. Merge the S/PDIF support from imx-spdif into driver fsl-asoc-card to extend the support of S/PDIF audio card with the use of ASRC devices. fsl-asoc-card uses slightly different DT properties than imx-spdif: * the "spdif-controller" property from imx-spdif is named "audio-cpu" in fsl-asoc-card. * fsl-asoc-card uses codecs explicitly declared in DT with "audio-codec". With an SPDIF, codec drivers spdif_transmitter and spdif_receiver should be used. Driver imx-spdif used instead the dummy codec and a pair of boolean properties, "spdif-in" and "spdif-out". To keep backward compatibility, support for "spdif-controller", "spdif-in" and "spdif-out" is also added to fsl-asoc-card. However, it is recommended to use the new properties if possible. It is better to declare transmitter and/or receiver in DT than using the dummy codec. DTs using compatible "fsl,imx-audio-spdif" are still compatible, and fsl-asoc-card will behave the same as imx-spdif for these DTs.

2024-07-08ASoC: fsl-asoc-card: add compatibility to use 2 codecs in dai-linksElinor Montmasson
Adapt the driver to work with configurations using two codecs or more. Modify fsl_asoc_card_probe() to handle use cases where 2 codecs are given in the device tree. This will be needed to add support for the SPDIF. Use cases using one codec will ignore any given codecs other than the first.

2024-07-08ASoC: fsl-asoc-card: add second dai link component for codecsElinor Montmasson
Add a second dai link component for codecs that will be used for use cases with 2 codecs. It is needed for future integration of the SPDIF support, which will use spdif_receiver and spdif_transmitter drivers. To prevent deferring in use cases using only one codec, also set by default the number of codecs to 1 for the relevant dai links.

2024-07-04ASoC: fsl: fsl_qmc_audio: Add support for non-interleaved mode.Herve Codina
The current fsl_qmc_audio works in interleaved mode. The audio samples are interleaved and all data are sent to (received from) one QMC channel. Using several QMC channels, non interleaved mode can be easily supported. 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 two modes are slightly different: - 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. - 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. Add support for the non-interleaved mode allowing multiple QMC channel per DAI. The DAI switches in non-interleaved mode when more that one QMC channel is available.

2024-07-04ASoC: fsl: fsl_qmc_audio: Identify the QMC channel involved in completion ↵Herve Codina
routines The current QMC audio driver uses only one QMC channel per DAI. The context used by QMC channel transfer (read and write) completion routines does not contains any QMC channel and the only one available per DAI is used to schedule the next transfer. This works pretty well with only one QMC channel per DAI. The future support for non-inlerleave mode will use several QMC channel per DAI. In that case, QMC channel transfer completion routines need to identify the QMC channel related to the completion. In order to fill this lack, even if identifying the current QMC channel among several QMC channels is not needed for the current code, add one indirection level and introduce the qmc_dai_chan data structrure. This structure contains the QMC channel involved in the completion and refererences to the runtime context (capture and playback) used by the DAI.

2024-07-04ASoC: fsl: fsl_qmc_audio: Split channel buffer and PCM pointer handlingHerve Codina
The driver mixes some internal values for channel DMA buffer handling and PCM pointer handling. In the currently supported interleaved mode, this mix does not lead to any issues but in order to prepare the support for the non-interleaved mode, having them clearly separated will ease the support and avoid additional computation to convert values used in channel DMA buffer management in values usable for PCM pointer. Use a specific set of variable for PCM pointer handling and an other set for channel DMA buffer.

One solution would be a small refactoring of the second parameter in dev_err_probe(), PTR_ERR(i2s_info_p->regs), to be the value of ret in the if statement. However, a nicer solution for debugging purposes, which is the point of this statement, would be to use the '%pe' specifier to symbolically print the error pointer value.

priv->pdev pointer was set after being used in fsl_asoc_card_audmux_init(). Move this assignment at the start of the probe function, so sub-functions can correctly use pdev through priv. fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the dev struct, used with dev_err macros. As priv is zero-initialised, there would be a NULL pointer dereference. Note that if priv->dev is dereferenced before assignment but never used, for example if there is no error to be printed, the driver won't crash probably due to compiler optimisations.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v6.9 This has been quite a small release, there's a lot of driver specific cleanups and minor enhancements but hardly anything on the core and only one new driver. Highlights include: - SoundWire support for AMD ACP 6.3 systems. - Support for reporting version information for AVS firmware. - Support DSPless mode for Intel Soundwire systems. - Support for configuring CS35L56 amplifiers using EFI calibration data. - Log which component is being operated on as part of power management trace events. - Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x
2024-02-23ASoC: soc-card: Fix missing locking in snd_soc_card_get_kcontrol()Richard Fitzgerald
snd_soc_card_get_kcontrol() must be holding a read lock on card->controls_rwsem while walking the controls list. Compare with snd_ctl_find_numid(). The existing function is renamed snd_soc_card_get_kcontrol_locked() so that it can be called from contexts that are already holding card->controls_rwsem (for example, control get/put functions). There are few direct or indirect callers of snd_soc_card_get_kcontrol(), and most are safe. Three require changes, which have been included in this patch: codecs/cs35l45.c: cs35l45_activate_ctl() is called from a control put() function so is changed to call snd_soc_card_get_kcontrol_locked(). codecs/cs35l56.c: cs35l56_sync_asp1_mixer_widgets_with_firmware() is called from control get()/put() functions so is changed to call snd_soc_card_get_kcontrol_locked(). fsl/fsl_xcvr.c: fsl_xcvr_activate_ctl() is called from three places, one of which already holds card->controls_rwsem: 1. fsl_xcvr_mode_put(), a control put function, which will already be holding card->controls_rwsem. 2. fsl_xcvr_startup(), a DAI startup function. 3. fsl_xcvr_shutdown(), a DAI shutdown function. To fix this, fsl_xcvr_activate_ctl() has been changed to call snd_soc_card_get_kcontrol_locked() so that it is safe to call directly from fsl_xcvr_mode_put(). The fsl_xcvr_startup() and fsl_xcvr_shutdown() functions have been changed to take a read lock on card->controls_rsem() around calls to fsl_xcvr_activate_ctl(). While this is not very elegant, it keeps the change small, to avoid this patch creating a large collateral churn in fsl/fsl_xcvr.c. Analysis of other callers of snd_soc_card_get_kcontrol() is that they do not need any changes, they are not holding card->controls_rwsem when they call snd_soc_card_get_kcontrol(). Direct callers of snd_soc_card_get_kcontrol(): fsl/fsl_spdif.c: fsl_spdif_dai_probe() - DAI probe function fsl/fsl_micfil.c: voice_detected_fn() - IRQ handler Indirect callers via soc_component_notify_control(): codecs/cs42l43: cs42l43_mic_shutter() - IRQ handler codecs/cs42l43: cs42l43_spk_shutter() - IRQ handler codecs/ak4118.c: ak4118_irq_handler() - IRQ handler codecs/wm_adsp.c: wm_adsp_write_ctl() - not currently used Indirect callers via snd_soc_limit_volume(): qcom/sc8280xp.c: sc8280xp_snd_init() - DAIlink init function ti/rx51.c: rx51_aic34_init() - DAI init function I don't have hardware to test the fsl/*, qcom/sc828xp.c, ti/rx51.c and ak4118.c changes. Backport note: The fsl/, qcom/, cs35l45, cs35l56 and cs42l43 callers were added since the Fixes commit so won't all be present on older kernels.
