by Shenghao Ding 31 Mar '23

31 Mar '23

Create tas2781 driver. Signed-off-by: Shenghao Ding <13916275206(a)139.com> --- Changes in v11: - Add comment on why use be32_to_cpup instead of be32_to_cpu - Simplify the code in tasdevice_add_config - Correct the wrong spelling comments in tasdevice_add_config Changes to be committed: modified: sound/soc/codecs/Kconfig modified: sound/soc/codecs/Makefile new file: sound/soc/codecs/tas2781-dsp.c new file:

[PATCH 00/18] ASoC: SOF: Intel: hda-mlink: HDaudio multi-link extension update
by Peter Ujfalusi 31 Mar '23

31 Mar '23

Hi, The following series adds the core support to handle the recently updated HDaudio multi-link support to hanlde non HDA links, like SoundWire/DMIC/SSP on Intel platform. For details, please see the first patch which documents the current mlink support (introduced at Skylake) and the new extensions, arriving with LNL. There is no change in functionality for existing HDA support, the extension is backwards compatible with existing implementations.

[PATCH V3 1/2] ASoC: max98363: add soundwire amplifier driver
by “Ryan 31 Mar '23

31 Mar '23

From: Ryan Lee <ryans.lee(a)analog.com> Added Analog Devices MAX98363 SoundWire Amplifier Driver. The MAX98363 is a SoundWire peripheral device that supports MIPI SoundWire v1.2-compatible digital interface for audio and control data. Signed-off-by: Ryan Lee <ryans.lee(a)analog.com> --- Changes from v1: Removed the standard SoundWire registers from the amp register table. Removed .of_match_table and .acpi_match_table. Removed vdd/dvddio control. Removed unnecessary source port control in .read_prop. Removed legacy from I2S driver not used for SoundWire driver. Removed .shutdown, .bus_config, and unused functions. Sorted include files in alphabetical order. Changes from v2: Changed .channels_max from 2 to 1. stream_config.ch_count is limited to .channels_max. Removed unused variables. rx_mask and slot from max98363_priv. sound/soc/codecs/Kconfig | 11 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/max98363.c | 464 ++++++++++++++++++++++++++++++++++++ sound/soc/codecs/max98363.h | 36 +++ 4 files changed, 513 insertions(+) create mode 100644 sound/soc/codecs/max98363.c create mode 100644 sound/soc/codecs/max98363.h diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index 03630d13d35f..4062fe3fbb1c 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -133,6 +133,7 @@ config SND_SOC_ALL_CODECS imply SND_SOC_MAX98925 imply SND_SOC_MAX98926 imply SND_SOC_MAX98927 + imply SND_SOC_MAX98363 imply SND_SOC_MAX98373_I2C imply SND_SOC_MAX98373_SDW imply SND_SOC_MAX98390 @@ -1133,6 +1134,16 @@ config SND_SOC_MAX98520 To compile this driver as a module, choose M here. +config SND_SOC_MAX98363 + tristate "Analog Devices MAX98363 Soundwire Speaker Amplifier" + depends on SOUNDWIRE + select REGMAP_SOUNDWIRE + help + Enable support for Analog Devices MAX98363 Soundwire + amplifier.

[PATCH v5] ASoC: dt-bindings: qcom,lpass-va-macro: Add missing NPL clock
by Krzysztof Kozlowski 30 Mar '23

30 Mar '23

Several devices (e.g. SC8280XP and SM8450) expect a NPL (Near Pad Logic) clock. Add the clock and customize allowed clocks per each variant. The clocks are also required by ADSP in all variants.

[PATCH v4] ASoC: dt-bindings: qcom,lpass-va-macro: Add missing NPL clock
by Krzysztof Kozlowski 30 Mar '23

30 Mar '23

Several devices (e.g. SC8280XP and SM8450) expect a NPL (Near Pad Logic) clock. Add the clock and customize allowed clocks per each variant. The clocks are also required by ADSP in all variants.

[PATCH] ASoC: dapm: Sort speakers after other outputs
by Mark Brown 30 Mar '23

30 Mar '23

Currently we sequence speakers with line and headphone outputs in DAPM. This works well when speakers are integrate into a CODEC but when there is an external speaker driver connected to a line or headphone output it can mean that the speaker driver ends up getting sequenced such that it picks up pops and clicks from the CODEC. Mask this by moving speakers after the other outputs in DAPM. We may want to consider doing this for headphones too but separate drivers are less common there and headphone drivers often also function as line outputs so the situation is less clear.
