2024-03-04ASoC: soc-core.c: Prefer to return dai->driver->name in snd_soc_dai_name_get()Chancel Liu1-6/+6
ASoC machine driver can use snd_soc_{of_}get_dlc() (A) to get DAI name for dlc (snd_soc_dai_link_component). In this function call dlc->dai_name is parsed via snd_soc_dai_name_get() (B). (A) int snd_soc_get_dlc(...) { ... (B) dlc->dai_name = snd_soc_dai_name_get(dai); ... } (B) has a priority to return dai->name as dlc->dai_name. In most cases card can probe successfully. However it has an issue that ASoC tries to rebind card. Here is a simplified flow for example: | a) Card probes successfully at first | b) One of the component bound to this card is removed for some | reason the component->dev is released | c) That component is re-registered v d) ASoC calls snd_soc_try_rebind_card() a) points dlc->dai_name to dai->name. b) releases all resource of the old DAI. c) creates new DAI structure. In result d) can not use dlc->dai_name to add new created DAI. So it's reasonable that prefer to return dai->driver->name in snd_soc_dai_name_get() because dai->driver is a pre-defined global variable. Also update snd_soc_is_matching_dai() for alignment.

2024-02-22ASoC: soc-core: tidyup strcmp() param on snd_soc_is_matching_dai()Kuninori Morimoto1-1/+1
snd_soc_is_matching_dai() checks DAI name, which is paired function with snd_soc_dai_name_get(). It checks dlc->dai_name and dai->name (A) or dai->driver_name (B) or dai->component->name (C) static int snd_soc_is_matching_dai(...) { ... if (strcmp(dlc->dai_name, dai->name) == 0) ~~~~~~~~~~~~~ ^^^^^^^^^(A) if (... strcmp(dai->driver->name, dlc->dai_name) == 0) (B)^^^^^^^^^^^^^^^^ ~~~~~~~~~~~~~ if (... strcmp(dlc->dai_name, dai->component->name) == 0) ~~~~~~~~~~~~~ ^^^^^^^^^^^^^^^^^^(C) ... } But (B) part order is different with (A) and (C) (= ^^^^ and ~~~~). This is not a big deal, but confusable to read. Fixup it.

2023-12-19ASoC: soc.h: don't create dummy Component via COMP_DUMMY()Kuninori Morimoto1-0/+24
Many ASoC drivers define CPU/Codec/Platform dai_link by below macro. SND_SOC_DAILINK_DEFS(link, (A) DAILINK_COMP_ARRAY(COMP_CPU("cpu_dai")), (B) DAILINK_COMP_ARRAY(COMP_CODEC("codec", "dai1"), (B) COMP_CODEC("codec", "dai2")), (C) DAILINK_COMP_ARRAY(COMP_EMPTY())); In this case, this macro will be converted to like below [o] = static struct snd_soc_dai_link_component (A) [o] link_cpus[] = {{ .dai_name = "cpu_dai" }}; (B) [o] link_codecs[] = {{ .dai_name = "dai1", .name = "codec" }, { .dai_name = "dai2", .name = "codec" }} (C) [o] link_platforms[] = {{ }}; CPU and Codec info will be filled by COMP_CPU() / COMP_CODEC (= A,B), and Platform will have empty data by COMP_EMPTY() (= C) in this case. Platform empty info will be filled when driver probe() (most of case, CPU info will be copied to use soc-generic-dmaengine-pcm). For example in case of DPCM FE/BE, it will be like below. Codec will be dummy Component / DAI in this case (X). SND_SOC_DAILINK_DEFS(link, DAILINK_COMP_ARRAY(COMP_CPU(...)), (X) DAILINK_COMP_ARRAY(COMP_DUMMY()), DAILINK_COMP_ARRAY(COMP_EMPTY())); (X) part will converted like below [o] link_codecs[] = {{ .name = "snd-soc-dummy", .dai_name = "snd-soc-dummy-dai", }} Even though we already have common asoc_dummy_dlc for dummy Component / DAI, this macro will re-create new dummy dlc. Some drivers defines many dai_link info via SND_SOC_DAILINK_DEFS(), this means many dummy dlc also will be re-created. This is waste of memory. If we can use existing common asoc_dummy_dlc at (X), we can avoid to re-creating dummy dlc, then, we can save the memory. At that time, we want to keep existing code as much as possible, because too many drivers are using this macro. But because of its original style, using common asoc_dummy_dlc from it is very difficult or impossible. So let's change the mind. The macro is used like below SND_SOC_DAILINK_DEFS(link, DAILINK_COMP_ARRAY(COMP_CPU(...)), (x) DAILINK_COMP_ARRAY(COMP_DUMMY()), DAILINK_COMP_ARRAY(COMP_EMPTY())); static struct snd_soc_dai_link dai_links[] = { { .name = ..., .stream_name = ..., (y) SND_SOC_DAILINK_REG(link), }, (y) part will be like below static struct snd_soc_dai_link dai_links[] = { { .name = ..., .stream_name = ..., ^ ... | .codecs = link_codecs, (y) .num_codecs = ARRAY_SIZE(link_codecs), v ... } This patch try to use trick on COMP_DUMMY() - #define COMP_DUMMY() { .name = "snd-soc-dummy", .dai_name = "snd-soc-dummy-dai", } + #define COMP_DUMMY() By this tric, (x) part will be like below. before [o] link_codecs[] = {{ .name = "snd-soc-dummy", .dai_name = "snd-soc-dummy-dai", }} after [o] link_codecs[] = { }; This is same as below [o] link_codecs[0]; This means it has pointer (link_codecs), but the array size is 0. (y) part will be like below. static struct snd_soc_dai_link dai_links[] = { { ... .codecs = link_codecs, .num_codecs = 0, ... }, This is very special settings that normal use usually not do, but new macro do. We can find this special settings on soc-core.c and fill it as "dummy DAI" (= asoc_dummy_dlc). By this tric, we can avoid to re-create dummy dlc and save the memory. This patch add tric at COMP_DUMMY() and add snd_soc_fill_dummy_dai() to fill dummy DAI.

2023-07-17ASoC: soc-core.c: enable multi ComponentKuninori Morimoto1-2/+30
Current ASoC Card is using dlc (snd_soc_dai_link_component) to find target DAI / Component to be used. Current dlc has below 3 items to identify DAI / Component (a) name for Component (b) of_node for Component (c) dai_name for DAI (a) or (b) is used to identify target Component, and (c) is used to identify DAI. One of the biggest issue on it today is dlc needs "name matching" for "dai_name" (c). It was not a big deal when we were using platform_device, because we could specify nessesary "dai_name" via its platform_data. But we need to find DAI name pointer from whole registered datas and/or each related driver somehow in case of DT, because we can't specify it. Therefore, Card driver parses DT and assumes the DAI, and find its name pointer. How to assume is based on each Component and/or Card. Next biggest issue is Component node (a)/(b). Basically, Component is registered when CPU/Codec driver was probed() (X). Here, 1 Component is possible to have some DAIs. int xxx_probe(struct platform_device *pdev) { ... (X) ret = devm_snd_soc_register_component(pdev->dev, &component_driver, &dai_driver, dai_driver_num); ... } The image of each data will be like below. One note here is "driver" is included for later explanation. +-driver------+ |+-component-+| || dai0|| || dai1|| || ...|| |+-----------+| +-------------+ The point here is 1 driver has 1 Component, because basically driver calles snd_soc_register_component() (= X) once. Here is the very basic CPU/Codec connection image. HW image SW image +-- Board ------------+ +-card--------------------------+ |+-----+ +------+| |+-driver------+ +-driver------+| || CPU | <--> |CodecA|| ||+-component-+| |+-component-+|| |+-----+ +------+| ||| dai|<=>|dai ||| +---------------------+ ||+-----------+| |+-----------+|| |+-------------+ +-------------+| +-------------------------------+ It will be very complex if it has multi DAIs.

But unfortunately it doesn't help us for now. Let's see soc_component_to_node() and snd_soc_is_matching_component() static struct device_node *soc_component_to_node(struct snd_soc_component *component) { ... (A) of_node = component->dev->of_node; ... } static int snd_soc_is_matching_component(...) { ... (B) if (dlc->of_node && component_of_node != dlc->of_node) ... } dlc checkes "of_node" to identify target component (B), but this "of_node" came from component->dev (A) which is added by snd_soc_register_component() (X) on probe(). This means we can have different "component->card", but have same "component->dev" in this case. Even though we calls snd_soc_register_component() (= X) multiple times, all Components have same driver's dev, thus it is impossible to identified the Component. And if it was impossible to identify Component, it is impossible to identify DAI on current implementation. So, how to handle above complex HW image today is 2 patterns. One is handles it as "1 big sound card". The SW image is like below. SW image +-card--------------------------+ |+-driver------+ +-driver------+| ||+-component-+| |+-component-+|| ||| ch0 dai|<=>|dai ||| ||| || |+-----------+|| ||| || +-------------+| ||| || +-driver------+| ||| || |+-component-+|| ||| ch1 dai|<->|dai ||| ||+-----------+| |+-----------+|| |+-------------+ +-------------+| +-------------------------------+ But the problem is not intuitive. We want to handle it as "2 Cards". 2nd pattern is like below. SW image +-card0-------------------------+ |+-driver------+ +-driver------+| ||+-component-+| |+-component-+|| ||| ch0 dai|<=>|dai ||| ||+-----------+| |+-----------+|| |+-------------+ +-------------+| +-------------------------------+ +-card1-------------------------+ |+-driver------+ +-driver------+| ||+-component-+| |+-component-+|| ||| ch1 dai|<=>|dai ||| ||+-----------+| |+-----------+|| |+-------------+ +-------------+| +-------------------------------+ It handles as "2 Cards", but CPU part needs to be probed as 2 drivers. It is also not intuitive. To solve this issue, we need to have multi Component support. In current implementation, we need to identify Component first to identify DAI, and it is using name matching to identify DAI. But how about to be enable to directly identify DAI by unique way instead of name matching ? In such case, we can directly identify DAI, then it can identify Component from DAI. For example Simple-Card / Audio-Graph-Card case, it is specifying DAI via its node. Simple-Card sound-dai = <&cpu-sound>; Audio-Graph-Card dais = <&cpu-sound>; If each CPU/Codec driver keeps this property when probing, we can identify DAI directly from Card. Being able to identify DAI directly means being able to identify its Component as well even though Component has same dev (= B). This patch adds new "dai_node" for it. To keeping compatibility, it checks "dai_node" first if it has, otherwise, use existing method (name matching).

2023-06-23ASoC: core: Always store of_node when getting DAI link componentMark Brown1-1/+2
The generic snd_soc_dai_get_dlc() contains a default translation function for DAI names which has factored out common code in a number of card drivers, resolving the dai_name and of_node either using a driver provided translation function or with a generic implementation. Unfortunately the of_node can't be set by the translation function since it currently doesn't have an interface to do that but snd_soc_dai_get_dlc() only initialises the of_node in the case where there is no translation function. This breaks the Meson support after conversion to use the generic helpers since the DPCM cards for it check which component of the SoC is connected to each link by checking the compatible for the component and the Meson components provide a custom operation so don't use the generic code. Fix this and potentially other cards by unconditionally storing the node in the dai_link_component, there shouldn't be a binding specific of_node selected since that's how we determine the translation function.

2022-11-18ASoC: core: Exit all links before removing their componentsCezary Rojewski1-3/+3
Flows leading to link->init() and link->exit() are not symmetric. Currently the relevant part of card probe sequence goes as: for_each_card_rtds(card, rtd) for_each_rtd_components(rtd, i, component) component->probe() for_each_card_rtds(card, rtd) for_each_rtd_dais(rtd, i, dai) dai->probe() for_each_card_rtds(card, rtd) rtd->init() On the other side, equivalent remove sequence goes as: for_each_card_rtds(card, rtd) for_each_rtd_dais(rtd, i, dai) dai->remove() for_each_card_rtds(card, rtd) for_each_rtd_components(rtd, i, component) component->remove() for_each_card_rtds(card, rtd) rtd->exit() what can lead to errors as link->exit() may still operate on resources owned by its components despite the probability of them being freed during the component->remove(). This change modifies the remove sequence to: for_each_card_rtds(card, rtd) rtd->exit() for_each_card_rtds(card, rtd) for_each_rtd_dais(rtd, i, dai) dai->remove() for_each_card_rtds(card, rtd) for_each_rtd_components(rtd, i, component) component->remove() so code found in link->exit() is safe to touch any component stuff as component->remove() has not been called yet.

2022-06-27ASoC: core: Switch core to new DAI naming flagCharles Keepax1-1/+1
Now all the drivers are updated to have the new legacy_dai_naming flag, update the core code so it also uses the new flag. Paving the way for the old non_legacy_dai_naming flag to be removed. It should be noted this patch will affect the CODEC drivers that don't specify the non_legacy_dai_naming flag. These drivers will update from using legacy DAI naming to the new scheme after this patch, this is being considered a fix as the intention was for all CODEC drivers to use the new scheme and all existing CODEC drivers were updated to do so before componentisation. This just corrects those devices that have snuck in since componentisation. The corrected devices are as follows: adau1372, cros_ec_codec, cs35l41, cs35l45, cx2072x, hdac_hda, jz4725/60/70, lpass-rx/tx/va/wsa-macro, max98504, max9877, mt6351/58/59, mt6660, pcm3060, rk3328, rt1308/16, rt5514, rt5677, rt700/11/15, rt9120, sdw-mockup, tlv320adc3xxx, tscs454, wcd9335/4x/8x, wsa881x Some of these devices are used in some in kernel machine drivers, however it appears all the usages use the actual DAI driver name (since snd_soc_find_dai checks both the DAI name and the DAI driver name).

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.
