ASoC: fsl_asrc_m2m: Add memory to memory function

2024-12-13T08:57:09+00:00

Implement the ASRC memory to memory function using the compress framework, user can use this function with compress ioctl interface. This feature can be shared by ASRC and EASRC drivers Signed-off-by: Shengjiu Wang Acked-by: Jaroslav Kysela Link: https://patch.msgid.link/20241212074509.3445859-5-shengjiu.wang@nxp.com Signed-off-by: Mark Brown

ASoC: fsl-asoc-card: merge spdif support from imx-spdif.c

2024-07-08T15:09:38+00:00

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.

ASoC: fsl: Use -y instead of -objs in Makefile

2024-05-08T02:39:18+00:00

*-objs suffix is reserved rather for (user-space) host programs while usually *-y suffix is used for kernel drivers (although *-objs works for that purpose for now). Let's correct the old usages of *-objs in Makefiles. Signed-off-by: Takashi Iwai Link: https://lore.kernel.org/r/20240507155540.24815-11-tiwai@suse.de Signed-off-by: Mark Brown

ASoC: fsl: mpc8610_hpcd: Remove unused driver

2023-11-22T14:29:27+00:00

The mpc8610_hpcd.c driver depends on CONFIG_MPC8610_HPCD which was removed in commit 248667f8bbde ("powerpc: drop HPCD/MPC8610 evaluation platform support"). That makes the driver unbuildable and unusable, so remove it.

ASoC: fsl: Add support for QMC audio

2023-03-05T23:37:10+00:00

The QMC audio is an ASoC component which provides DAIs that use the QMC (QUICC Multichannel Controller) to transfer the audio data. It provides as many DAIs as the number of QMC channels it references.

ASoC: imx-card: Add imx-card machine driver

2021-05-20T16:57:30+00:00

Add machine driver for i.MX boards, which supports AK4458/AK5558/AK4497/AK5552 DAC/ADC attached to SAI interface currently, but these DAC/ADCs are not only supported codecs. This machine driver is designed to be a more common machine driver for i.MX platform, it can support widely cpu dai interface and codec dai interface.

ASoC: imx-pcm-rpmsg: Add platform driver for audio base on rpmsg

2021-03-25T13:58:10+00:00

Platform driver based on rpmsg is the interface for sending and receiving rpmsg to and from M core. It will tell the Cortex-M core sound format/rate/channel, where is the data buffer, where is the period size, when to start, when to stop and when suspend or resume happen, each this behavior there is defined rpmsg command. Especially we designed the low power audio case, that is to allocate a large buffer and fill the data, then Cortex-A core can go to sleep mode, Cortex-M core continue to play the sound, when the buffer is consumed, Cortex-M core will trigger the Cortex-A core to wake up.
