ASoC: soc-utils: Add helper to calculate BCLK from TDM info

2022-04-05T17:27:55Z

Add a helper function snd_soc_tdm_params_to_bclk() to calculate the bclk from params info and the tdm sots configuration. When using a TDM frame of N slots of width W bits: bclk = sample_rate * N * W As a convenience to simplify calling code, if the slot count or slot width are 0 a value will be obtained from the params. This allows calling code to use this one function to handle cases of TDM where only one parameter is fixed, or I2S where the slot width is fixed (for example to set a 32-bit slot for 24-bit samples). Also as a convenience the slot count can optionally be rounded up to a multiple. This is mainly useful for I2S systems, since I2S has two phases of LRCLK the number of slots is always a multiple of 2.

ASoC: Stop dummy from overriding hwparams

2021-10-29T15:49:45Z

In case that there are other components assigned to runtime device, depending on order dummy component can override their params with its own, which shouldn't happen. Check if there are any other components assigned to rtd and if so, skip setting hwparams. Occurs when using topology where 'snd-soc-dummy' gets assigned by default as codec and platform component. Alternative approach would be to copy whole dummy handling and rename it to "snd-soc-null" or something similar. And remove hwparams assignment to make it really do nothing.

ASoC: soc-core: add snd_soc_runtime_get_dai_fmt()

2021-06-07T14:55:12Z

ASoC is using dai_link which specify DAI format (= dai_link->dai_fmt), and it is selected by "Sound Card" driver in corrent implementation. In other words, Sound Card *needs* to setup it. But, it should be possible to automatically selected from CPU and Codec driver settings. This patch adds new .auto_selectable_formats support at snd_soc_dai_ops. By this patch, dai_fmt can be automatically selected from each driver if both CPU / Codec driver had it. Automatically selectable *field* is depends on each drivers. For example, some driver want to select format "automatically", but want to select other fields "manually", because of complex limitation. Or other example, in case of both CPU and Codec are possible to be clock provider, but the quality was different. In these case, user need/want to *manually* select each fields from Sound Card driver. This .auto_selectable_formats can set priority. For example, no limitaion format can be HI priority, supported but has picky limitation format can be next priority, etc. It uses Sound Card specified fields preferentially, and try to select non-specific fields from CPU and Codec driver automatically if all drivers have .auto_selectable_formats. In other words, we can select all dai_fmt via Sound Card driver same as before.

ASoC: soc-xxx: add asoc_substream_to_rtd()

2020-07-23T18:07:19Z

Current soc-xxx are getting rtd from substream by rtd = substream->private_data; But, getting data from "private_data" is very unclear. This patch adds asoc_substream_to_rtd() macro which is easy to understand that rtd from substream.

ASoC: add soc-component.c

2019-08-05T15:16:19Z

ALSA SoC has many snd_soc_component_xxx(), but these are randomly located in many files. Because of it, code is difficult to read. This patch creates new soc-component.c, and moves existing snd_soc_component_xxx() into it. But not yet fully. We need more cleanup it.

ASoC: soc-utils: Rename dummy_dma_ops to snd_dummy_dma_ops

2018-09-27T22:15:46Z

The symbols 'dummy_dma_ops' is declared with different data types by sound/soc/soc-utils.c and arch/arm64/include/asm/dma-mapping.h. This leads to conflicts when soc-utils.c (indirectly) includes dma-mapping.h: sound/soc/soc-utils.c:282:33: error: conflicting types for 'dummy_dma_ops' static const struct snd_pcm_ops dummy_dma_ops = { ^ ... arch/arm64/include/asm/dma-mapping.h:27:33: note: previous declaration of 'dummy_dma_ops' was here extern const struct dma_map_ops dummy_dma_ops; ^ Rename the symbol in soc-utils.c to 'snd_dummy_dma_ops' to avoid the conflict.
