26 Mar '24

echo /lib/firmware/fw.elf > /sys/class/remoteproc/remoteproc0/firmware (A) echo start > /sys/class/remoteproc/remoteproc0/state (B) echo stop > /sys/class/remoteproc/remoteproc0/state The rpmsg sound card is registered in (A) and unregistered in (B). After "start", imx-audio-rpmsg registers devices for ASoC platform driver and machine driver. Then sound card is registered. After "stop", imx-audio-rpmsg unregisters devices for ASoC platform driver and machine driver. Then sound card is unregistered. changes in v2 - Fix build errors reported by kernel test robot changes in v3 - Add a new patch for fsl_rpmsg to register CPU DAI with rpmsg channel name - Update imx-rpmsg.c to get DT node of ASoC CPU DAI device with rpmsg channel name instead of using undocumented bindings Chancel Liu (5): ASoC: fsl: imx-pcm-rpmsg: Register component with rpmsg channel name ASoC: fsl: imx-audio-rpmsg: Register device with rpmsg channel name ASoC: fsl: Let imx-audio-rpmsg register platform device for card ASoC: fsl: fsl_rpmsg: Register CPU DAI with name of rpmsg channel ASoC: fsl: imx-rpmsg: Update to correct DT node sound/soc/fsl/fsl_rpmsg.c | 43 ++++++++++++++++++++------------- sound/soc/fsl/imx-audio-rpmsg.c | 21 +++++++++++++--- sound/soc/fsl/imx-pcm-rpmsg.c | 11 ++++++--- sound/soc/fsl/imx-rpmsg.c | 28 ++++++++++++++------- 4 files changed, 71 insertions(+), 32 deletions(-) -- 2.43.0

[PATCH 0/7] ASoC: mediatek: AFE drivers cleanups
by AngeloGioacchino Del Regno 26 Mar '24

26 Mar '24

This series converts MediaTek AFE drivers' probe functions to use dev_err_probe() and devm functions where possible and, in some cases, dropping the .remove_new() callback, reducing the size. Cheers!

[PATCH v11] ASoc: tas2783: Add tas2783 codec driver
by Shenghao Ding 26 Mar '24

26 Mar '24

The tas2783 is a smart audio amplifier with integrated MIPI SoundWire interface (Version 1.2.1 compliant), I2C, and I2S/TDM interfaces designed for portable applications. An on-chip DSP supports Texas Instruments SmartAmp speaker protection algorithm. The integrated speaker voltage and current sense provides for real-time monitoring of loudspeakers. The ASoC component provides the majority of the functionality of the device, all the audio functions. Signed-off-by: Shenghao Ding <shenghao-ding(a)ti.com> --- Change in v11: - simplify tasdevice_set_sdw_stream - fixed some Linux coding style - fixed the spelling mistakes - Select left/right channel based on unique id - a longer description has been added - remove unused crc8 in KCONFIG - Invert of RE here means reciprocal of RE - correct indentation - correct the wrong pow calibrated register - correct comment on RESET register - fixed usually lines don't end with an open parenthesis - fixed tasdevice_sdw_shutdown - use defines for function, entity, etc. for readable - remove unnecessary codec_lock in component_probe() - remove struct sdw_stream_data - remove unused macro definitions - use BIT(2) and BIT(1) instead of 0x2 and 0x1 - implement pm_runtime - reg_start is u8, reg_start + i only adds i byte, it should be reg_start + i * 4, because the calibration values - fixed total_sz in tas2783_calibration - add a define for TASDEVICE_REG(0, 0, 0x0a) - rework macro style in header file - Add select CRC32 - rewrite the mute and the return value handling - Add comments on bin file - Add link_id into the fw name to distinguish the same sdw id on different sdw id. - remove unnecessary mutex_lock - use set_active() in tasdevice_io_init and move all other parts in the probe. - move pm_runtime_get_noresume to the probe - fix the return value of putvol function - add put_noidle in tasdevice_sdw_remove - remove unused header file(of.h) - correct the style of the multi-line comment - Set the readable registers in tas2783_readable_register for debugfs - Use new PM macros - Use default put and get inline SOC_SINGLE_RANGE_TLV and SOC_SINGLE_SX_TLV - Use respective %pt to log the calibrated time - Remove unnecessary struct tm - Add trailing comma tasdevice_dapm_widgets and tasdevice_audio_map - Rewrite the return value handling in tasdevice_sdw_probe - use dev_num instead of id.unique_id - rework the log - Add code to check the size of calibrated data in UEFI - Add description of Layout of calibrated Data in UEFI - switch back link_id and unique_id to identify the devcie - unique_id offset as the device index of the calibrated data - update calibrated data layout stored in UEFI, add link_id and unique_id into the calibrated data in case of tas2783 sitting in different SDQW buses. - correct the wrong unique_id - set the unique_id as hex style in dsp bin file name - use __func__ in the dev_err message in two identical logs intas2783_apply_calibv1/v2. - In tas2783_apply_calibv2, the very least move initializations to a different line. - No need for separate j variable, reuse i in tasdevice_read_prop. - remove unused "struct sdw_bus_params params", unsigned char dev_name[32] pstream, and chip_id - define dspfw_binaryname as a local variable in tasdevice_comp_probe. - reduce a lot of indentation in tasdevice_mute and spilte tasdevice_mute into tasdevice_enable_echo_ref and tasdevice_playback - remove tas2783_reg_defaults - use REGCACHE_MAPLE instead of REGCACHE_RBTREE - define fw_node_sz to store the node size --- sound/soc/codecs/Kconfig | 16 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tas2783-sdw.c | 893 +++++++++++++++++++++++++++++++++ sound/soc/codecs/tas2783.h | 107 ++++ 4 files changed, 1018 insertions(+) create mode 100644 sound/soc/codecs/tas2783-sdw.c create mode 100644 sound/soc/codecs/tas2783.h diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index f78ea2f86fa6..939384837d5e 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -248,6 +248,7 @@ config SND_SOC_ALL_CODECS imply SND_SOC_TAS2781_COMLIB imply SND_SOC_TAS2781_FMWLIB imply SND_SOC_TAS2781_I2C + imply SND_SOC_TAS2783 imply SND_SOC_TAS5086 imply SND_SOC_TAS571X imply SND_SOC_TAS5720 @@ -1880,6 +1881,21 @@ config SND_SOC_TAS2781_I2C algo coefficient setting, for one, two or even multiple TAS2781 chips. +config SND_SOC_TAS2783 + tristate "Texas Instruments TAS2783 speaker amplifier (sdw)" + depends on SOUNDWIRE + depends on EFI + select REGMAP + select REGMAP_SOUNDWIRE + select CRC32 + select CRC32_SARWATE + help + Enable support for Texas Instruments TAS2783 Smart Amplifier + Digital input mono Class-D and DSP-inside audio power amplifiers. + TAS2783 supports the MIPI SoundWire v1.2 compatible interface + for audio and control data.

Scan hardware to find speakers not detected by OS
by Jacek Blocki 26 Mar '24

26 Mar '24

Hello, In Alsa-devel Digest, Vol 205, Issue 136 there is my message on internal spekaker and headphones not working on Huawei D14 laptop. SImilar issue was reported in Vol 205, Issue 142 (No sound "dummy output" - snd_hda_intel on Pop OS 22.04 LTS on Acer chromebook). Is there any tool/troubleshooting guide allowing to diagnose above problem? In my cases (Huawei laptop) i guess OS does not detect speakers. Is there any way to scan hardware to find components undetected by OS? Regards, Jacek Blocki

alsa-project/alsa-ucm-conf pull request #406 was opened from kholk: A later revision of the MT8195 Cherry Tomato Chromebook (Acer Chromebook Spin 513 CP513-2H, Revision 3 and 4) are using the RT5682s codec instead of RT5682i. The differences are only about a couple of missing switches, where the 'i' variant had a switch for the L/R Headphone output and a configurable DAC L/R Mux, while the 's' one misses the mux control and solely relies on the main Headphone Switch. This configuration has been tested on Arch Linux with Pipewire 10.03 + WirePlumber.

[PATCH 0/2] ALSA/ASoC/SOF: SSP dev_type support
by Peter Ujfalusi 26 Mar '24

26 Mar '24

Hi, SOF always passed 0 as dev_type to intel_nhlt_get_endpoint_blob() when looking up the blob from the NHLT table. This causes issues since alsa-utils commit 3a47ef2487ed ("topology: nhlt: intel: support more device types and directions") The dev_type is no longer always 0 in the topology embedded NHLT table resulting lookup failures for analog codecs since they will have dev_type=4. With SOF the dev_type is not used, we always use the SSP port index for looking up the configuration blob. The solution for the issue is to fetch the dev_type for the SSP port and feed it back to the intel_nhlt_get_endpoint_blob() to be able to find the configuration regardless of the assigned dev_type.

[PATCH] ASoC: cs-amp-lib: Check for no firmware controls when writing calibration
by Richard Fitzgerald 25 Mar '24

25 Mar '24

From: Simon Trimmer <simont(a)opensource.cirrus.com> When a wmfw file has not been loaded the firmware control descriptions necessary to write a stored calibration are not present. In this case print a more descriptive error message. The message is logged at info level because it is not fatal, and does not necessarily imply that anything is broken.
