[PATCH v3] ASoC: codecs: Add power domains support in digital macro codecs
by Srinivasa Rao Mandadapu 25 Feb '22

25 Feb '22

Add support for enabling required power domains in digital macro codecs. macro and dcodec power domains are being requested as clocks by HLOS in ADSP based architectures and ADSP internally handling as powerdomains. In ADSP bypass case need to handle them as power domains explicitly.

[PATCH] ASoC: SOF: Declare sof_compress_ops in sof-priv.h
by Peter Ujfalusi 25 Feb '22

25 Feb '22

Fix the following sparse error: sound/soc/sof/compress.c:310:25: error: symbol 'sof_compressed_ops' was not declared. Should it be static? Do not enable set the pd->compress_ops yet as it is not a valid assumption that real compress support really works when CONFIG_SND_SOC_SOF_COMPRESS is set as the HDA Probes support also selects it, but compressed audio is not supported (yet) on Intel platforms.

[PATCH] ASoC: SOF: pcm: Add compress_ops for SOF platform component driver
by Daniel Baluta 24 Feb '22

24 Feb '22

From: Daniel Baluta <daniel.baluta(a)nxp.com> Now that sof_compressed_ops initial implementation was merged we can enable it in SOF platform component driver.

[PATCH] ASoC: tlv320adc3xxx: Fix buggy return value
by Ricard Wanderlof 24 Feb '22

24 Feb '22

snd_soc_component_update_bits returns 1 if the operation was successful and some bits were changed, so we cannot return this value directly as it can be interpreted as an error. Instead, do some minor mangling to avoid inadvertently returning an error.

[PATCH V2 0/1] ASoC: compress: propagate the error code from the
by Raghu Bankapur 24 Feb '22

24 Feb '22

Propagate the error code from the compress framework for the timestamp query. This error code will be used by the client to handle the error case scenarios gracefully. This propgated error is used by direct client like Audio HAL through IOCTL -SNDRV_COMPRESS_TSTAMP response, further this response is sent to upper layer, based on this error audio related usecases related to render position and presentation are handled. Changes since v1: - Remove initialization for ret, since it is updated by pointer function - Added new line after ret declaration Raghu Bankapur (1): ASoC: compress: propagate the error code from the compress framework sound/core/compress_offload.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) -- 2.17.1
