2024-11-01ASoC: cleanup function parameter for rtd and its idKuninori Morimoto
some functions had parameter like below xxx(..., rtd, ..., id); This "id" is rtd->id. We don't need to have "id" on each functions because we can get it from "rtd". Let's cleanup it.

2024-11-01ASoC: rename rtd->num to rtd->idKuninori Morimoto
Current rtd has "num". It sounds/looks like size of rtd or something, but it will be mainly used at snd_pcm_new() as "device index". This naming is confusable. Let's rename it to "id" Some drivers are using rtd->num, so let's keep it so far, and remove it if all user was switched.

2024-08-06ASoC: remove bespoke trigger supportKuninori Morimoto
Bespoke trigger support was added when Linux v3.5 by this patch. commit 07bf84aaf736781a283b1bd36eaa911453b14574 ("ASoC: dpcm: Add bespoke trigger()") test-component driver is using it, but this is because it indicates used function for debug/trace purpose. Except test-component driver, bespoke trigger has never been used over 10 years in upstream. We can re-support it if needed in the future, but let's remove it for now, because it just noise in upstream.

Several ASoC functions receive pointers to data which is not modified, e.g. pointers to 'snd_soc_dai', 'snd_soc_pcm_runtime', 'snd_pcm_hw_params' and 'snd_soc_dai_link'.

2022-11-23ASoC: soc-dai: Do not call snd_soc_link_be_hw_params_fixup() twiceRichard Fitzgerald
For a BE link snd_soc_link_be_hw_params_fixup() is called by dpcm_be_dai_hw_params() to initialize the params before it passes them to __soc_pcm_hw_params(). Then __soc_pcm_hw_params() refines params to match the BE codec and passes that to snd_soc_dai_hw_params(). The second call of snd_soc_link_be_hw_params_fixup() within snd_soc_dai_hw_params() was overwriting the refined params with the original BE CPU DAI params. This would then lead to various problems, for example passing an invalid number of channels to the codec driver hw_params(), or enabling more AIF widgets on the codec than are actually mapped by TDM slots. These errors may not be noticed on a simple 1:1 link between one CPU DAI and one codec DAI, because most likely they have the same DAI config (though this is not necessarily true, for example if the CPU end has dummy TDM slots to achieve a desirable BCLK). For 1:N mappings there are likely to be multiple codecs using different subsets of the TDM slots and this overwriting of the refined params can cause incorrect configuration of each codec on the link. The erroneous extra call to the BE fixup function() was introduced by: commit a655de808cbd ("ASoC: core: Allow topology to override machine driver FE DAI link config.") at that time, the call to the BE fixup was already done by dpcm_be_dai_hw_params(), which was introduced several years earlier by: commit 01d7584cd2e5 ("ASoC: dpcm: Add Dynamic PCM core operations.") The erroneous code has changed and moved to a different source file since the patch that introduced it, so this fix patch won't directly apply as a fix on top of code older than: commit 8b4ba1d31771 ("ASoC: soc-dai: fix up hw params only if it is needed") though it can be applied with some minor adjustment to code before that patch but after: commit aa6166c2ac28 ("ASoC: soc-dai: mv soc_dai_hw_params() to soc-dai") On any tree older than that the code is in soc-pcm.c.

2022-08-19ASoC: Change handling of unimplemented set_bclk_ratioMartin Povišer
If a 'set_bclk_ratio' call is attempted on a DAI not implementing the method, make it an -ENOSUPP error instead of -EINVAL. Assume the DAI can still be okay with the ratio, just does not care to register a handler. No current in-tree users of snd_soc_dai_set_bclk_ratio seem to inspect the return value, but -ENOSUPP disables an error print from within the common soc_dai_ret return filter. With the new behavior a machine driver can do a blanket 'set_bclk_ratio' on all DAIs on a bus, some of which may care about the ratio, some of which may not.

2022-06-06ASoC: core: Add set_fmt_new callback that directly specifies providerCharles Keepax
The original set_fmt callback always passes clock provider/consumer with respect to the CODEC. This made sense when the framework was directly broken down into platforms and CODECs. Now everything is componentised it simplifies things if each side of the link is just told if it is provider or consumer of the clocks. To start this migration add a new callback that can be used to receive a direct specification of clocking. As there are more CODEC drivers than platform drivers, we make the new flags identical to the old CODEC flags meaning CODEC drivers will not require an update.

2021-06-07ASoC: soc-core: add snd_soc_runtime_get_dai_fmt()Kuninori Morimoto
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.

The idea of having bit-flag or counter is not enough for this purpose. For example if one DAI is used for 2xPlaybacks for some reasons, and if 1st Playback was succeeded but 2nd Playback was failed, 2nd Playback rollback doesn't need to call shutdown. But it has succeeded bit-flag or counter via 1st Playback, thus, 2nd Playback rollback will call unneeded shutdown. And 1st Playback's necessary shutdown will not be called, because bit-flag or counter was cleared by wrong 2nd Playback rollback. To avoid such case, this patch marks substream pointer when hw_params() was succeeded. If rollback needed, it will check rollback flag and marked substream pointer. One note here is that it cares *previous* hw_params() only now, but we might want to check *whole* marked substream in the future.

Now, soc_pcm_open/close() are handling => 1) snd_soc_dai_startup/shutdown() 2) snd_soc_link_startup/shutdown() 3) snd_soc_component_module_get/put() 4) snd_soc_component_open/close() 5) pm_runtime_put/get() This patch is for 1) snd_soc_dai_startup/shutdown(). The idea of having bit-flag or counter is not enough for this purpose. For example if one DAI is used for 2xPlaybacks for some reasons, and if 1st Playback was succeeded but 2nd Playback was failed, 2nd Playback rollback doesn't need to call shutdown. But it has succeeded bit-flag or counter via 1st Playback, thus, 2nd Playback rollback will call unneeded shutdown. And 1st Playback's necessary shutdown will not be called, because bit-flag or counter was cleared by wrong 2nd Playback rollback. To avoid such case, this patch marks substream pointer when startup() was succeeded. If rollback needed, it will check rollback flag and marked substream pointer. One note here is that it cares *current* startup() only now. but we might want to check *whole* marked substream in the future. This patch is using macro named "push/pop", so that it can be easily update.

commit 25612477d20b52 ("ASoC: soc-dai: set dai_link dpcm_ flags with a helper") added snd_soc_dai_link_set_capabilities(). But it is using snd_soc_find_dai() (A) which is required client_mutex (B).

2020-07-31ASoC: core: use less strict tests for dailink capabilitiesPierre-Louis Bossart
Previous updates to set dailink capabilities and check dailink capabilities were based on a flawed assumption that all dais support the same capabilities as the dailink. This is true for TDM configurations but existing configurations use an amplifier and a capture device on the same dailink, and the tests would prevent the card from probing. This patch modifies the snd_soc_dai_link_set_capabilities() helper so that the dpcm_playback (resp. dpcm_capture) dailink capabilities are set if at least one dai supports playback (resp. capture). Likewise the checks are modified so that an error is reported only when dpcm_playback (resp. dpcm_capture) is set but none of the CPU DAIs support playback (resp. capture).
