ASoC: SOF: Intel: Add a is_amp flag to fix the wrong name prefix

2026-03-26T16:22:42+00:00

According to the Intel sof design, it will create the name prefix appended with amp index for the amp codec only, such as: rt1318-1, rt1318-2, etc... But the rt1320 is a codec with amp and mic codec functions, it doesn't have the amp index in its name prefix as above. And then it will be hard to identify the codec if in multi-rt1320 case. So we add a flag to force the amp index to be appended.

ASoC: sdw_utils: add vendor_id to asoc_sdw_codec_info

2026-03-24T13:17:18+00:00

struct asoc_sdw_codec_info has part_id which is not sufficient to uniquely identify devices. This change adds the vendor_id field and updates the codec_info list with the corresponding vendor id as per the Manufacturer's id in https://mid.mipi.org/ Signed-off-by: Niranjan H Y Reviewed-by: Bard Liao Reviewed-by: Pierre-Louis Bossart Reviewed-by: Charles Keepax Link: https://patch.msgid.link/20260324041300.784-1-niranjan.hy@ti.com Signed-off-by: Mark Brown

ASoC: soc_sdw_utils: Add device info for CS47L47

2026-02-24T15:53:42+00:00

Add a device info entry for the Cirrus Logic CS47L47. CS47L47 has UAJ (headset speaker + mic + jack detect) and DMICs. The audio ports are similar to the CS42L45 so can be based on the CS42L45 code.

ASoC: intel: sof_sdw: Add ability to have auxiliary devices

2025-11-27T19:18:49+00:00

Currently the sof_sdw machine driver assumes that all devices involved in the sound card are connected through a DAI link. However for SDCA devices we still want the HID (Human Interface Device, used for jack buttons) to be part of the sound card, but it contains no DAI links. Add support into the machine driver to specify a list of auxiliary devices to merged into the card.

As SDCA devices will support each DAI link on a different child device, move the codec name from codec_info to each dai_info. To allow the appropriate function device to be bound to each DAI link.

Currently, the codec name_prefix of Intel SoundWire machine driver is from the ACPI match table. We can have it in the asoc_sdw_codec_info struct as a default name_prefix of a codec if there is no corresponding audio config found in the ACPI match table.

ASoC: sdw_utils: add component_name string to dai_info

2025-06-25T14:13:45+00:00

Currently the sdw machine driver uses different way to get the component name from the DAI name for different codecs in the rtd_init callback. It means that we need to rely on the rtd_init callback to get the component name. Add an optional component string to the asoc_sdw_dai_info struct allows the machine driver to get the component name directly. The commit adds the component names for the AMP dais for the preparation to set card->components string for combined speaker configs.
