[alsa-devel] [PATCH] sound/soc/codecs/tas5720.c: add ACPI support
by Nikolaus Voss 04 Jul '19

04 Jul '19

Add support for ACPI enumeration for tas5720 and tas5722. Use device_match API to unify access to driver data for DT and ACPI. Aggregate variant stuff into its own struct and directly reference it in variant data for i2c/of/acpi_device_id.

[alsa-devel] [PATCH 00/46] ASoC: consider CPU-Platform possibility
by Kuninori Morimoto 03 Jul '19

03 Jul '19

Hi Mark My posted patch (= "ASoC: xxx: don't select unnecessary Platform") removed Platform component settings from Card driver if it selects CPU as Platform. ALSA SoC will ignore duplicate component. I thought these Card driver don't need Platform, but it was wrong. Some CPU component is using generic DMAEngine component. In such case, CPU and Platform have same name but different component, and some Card needs both. My posted above patch breaks (not all but) few Cards. We can revert one-by-one if we get report, but better to revert all from stable kernel point of view. These patches revert all patches. I'm so sorry to bother you and users. I hope these can fixup issue.

[alsa-devel] [PATCH v6] ASoC: max98090: remove 24-bit format support if RJ is 0
by Yu-Hsuan Hsu 02 Jul '19

02 Jul '19

The supported formats are S16_LE and S24_LE now. However, S24_LE is not supported when TDM is 0 and it is not in the right justified mode. We should remove 24-bit format in that situation to avoid triggering error. Signed-off-by: Yu-Hsuan Hsu <yuhsuan(a)chromium.org> --- Changed the order of the conditional. Remove the snd_pcm_hw_constraint_msbits function. Use removing 24 bits format instead of fixing at 16 bits format. sound/soc/codecs/max98090.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/sound/soc/codecs/max98090.c b/sound/soc/codecs/max98090.c index 7619ea31ab50..9fbb4c31bcf1 100644 --- a/sound/soc/codecs/max98090.c +++ b/sound/soc/codecs/max98090.c @@ -1909,6 +1909,24 @@ static int max98090_configure_dmic(struct max98090_priv *max98090, return 0; } +static int max98090_dai_startup(struct snd_pcm_substream *substream, + struct snd_soc_dai *dai) +{ + struct snd_soc_component *component = dai->component; + struct max98090_priv *max98090 = snd_soc_component_get_drvdata(component); + unsigned int fmt = max98090->dai_fmt; + + /* + * When TDM = 0, remove 24-bit format support if it is not in right + * justified mode. + */ + if ((fmt & SND_SOC_DAIFMT_FORMAT_MASK) != SND_SOC_DAIFMT_RIGHT_J && + !max98090->tdm_slots) + substream->runtime->hw.formats &= ~SNDRV_PCM_FMTBIT_S24_LE; + + return 0; +} + static int max98090_dai_hw_params(struct snd_pcm_substream *substream, struct snd_pcm_hw_params *params, struct snd_soc_dai *dai) @@ -2316,6 +2334,7 @@ EXPORT_SYMBOL_GPL(max98090_mic_detect); #define MAX98090_FORMATS (SNDRV_PCM_FMTBIT_S16_LE | SNDRV_PCM_FMTBIT_S24_LE) static const struct snd_soc_dai_ops max98090_dai_ops = { + .startup = max98090_dai_startup, .set_sysclk = max98090_dai_set_sysclk, .set_fmt = max98090_dai_set_fmt, .set_tdm_slot = max98090_set_tdm_slot, -- 2.22.0.410.gd8fdbe21b5-goog

[alsa-devel] [RFC PATCH 0/5] ASoC: codecs: Add WSA881x Smart Speaker amplifier support
by Srinivas Kandagatla 02 Jul '19

02 Jul '19

This patchset adds support to WSA8810/WSA8815 Class-D Smart Speaker Amplifier which is SoundWire interfaced. This also adds support to some missing bits in SoundWire bus layer like Device Tree support and module_sdw_driver macro. This patchset along with DB845c machine driver and WCD934x codec driver has been tested on SDM845 SoC based DragonBoard DB845c with two WSA8810 speakers. Most of the code in this driver is rework of Qualcomm downstream drivers used in Andriod. Credits to Banajit Goswami and Patrick Lai's Team. TODO: Add thermal sensor support in WSA881x.

[alsa-devel] [PATCH v2 0/2] ALSA: hda: Widget memory fixes
by Evan Green 01 Jul '19

01 Jul '19

This series fixes concurrency issues with the sysfs widget array. The first function patches up the locking that was introduced recently to protect more of the data structure. The second patch fixes a race between a reinit and the initial population of the array which could result in a length and array getting out of sync.

OK, it could be because SND_SOC_DAIFMT_INV_MASK must be SND_SOC_DAIFMT_NB_NF. But then Alexandre's blog contains an error, because the dac TDM sets frame-inversion in its dts (and it should not). -- Kind Regards, *Jürgen Lambrecht* R&D Associate Tel: +32 51 303045 www.televic-rail.com <https://www.televic-rail.com> Televic Rail NV - Leo Bekaertlaan 1 - 8870 Izegem - Belgium Company number 0825 539 581 - RPR Kortrijk

[alsa-devel] [PATCH] ALSA: xen-front: fix unintention integer overflow on left shifts
by Colin King 01 Jul '19

01 Jul '19

From: Colin Ian King <colin.king(a)canonical.com> Shifting the integer value 1 is evaluated using 32-bit arithmetic and then used in an expression that expects a 64-bit value, so there is potentially an integer overflow. Fix this by using the BIT_ULL macro to perform the shift.
