2022-06-07ASoC: simple-card-utils: Make asoc_simple_clean_reference() return voidUwe Kleine-König1-3/+4
asoc_simple_clean_reference() returns zero unconditionally. Letting it return void instead makes it easier to see in the caller that there is no error to handle. This is a preparation for making platform remove callbacks return void.

2022-06-06ASoC: simple-card-utils: rename asoc_simple_init_dai_link_params() to asoc_simple_init_for_codec2codec()Kuninori Morimoto1-2/+2
commit 95cfc0a0aaf5752071 ("ASoC: simple-card: Add support for codec2codec DAI links") added the function asoc_simple_init_dai_link_params() to initialize dai_link "params". It is very straight naming, but difficult to noticed that it is for Codec2Codec support. Handling Codec2Codec is one of very tricky part on ALSA SoC, thus it is very important to clarify it. This patch renames the function name.

2022-06-06ASoC: simple-card-utils: Move snd_soc_component_is_codec to be localCharles Keepax1-1/+6
The helper function snd_soc_component_is_codec is based off the presence of the non_legacy_dai_naming flag. This isn't super robust as CPU side components may also specify this flag, and indeed the kernel already contains a couple that do. After componentisation there isn't really a totally robust solution to identifying what is a CODEC driver, without introducing a flag specifically for that purpose, and really the desirable direction to move in is that the distinction doesn't matter. This patch does two things to try to mitigate these problems. Firstly, now that all the other users of the helper function have been removed, it makes the helper function local to the driver rather, than being part of the core. This should help to discourage any new code from being created that depends on the CODEC driver distinction. Secondly, it updates the helper function itself to use the endianness flag rather than the non_legacy_dai_naming flag. The endianness flag is definitely invalid on a CPU side component, so it a more reliable indicator that the device is definitely a CODEC. The vast majority of buses require the CODEC to set the endianness flag, so the number of corner cases should be fairly minimal. It is worth noting that CODECs sending audio over SPI, or built into the CPU CODECs are potential corner cases, however the hope is that in most cases those types of devices do not consitute a simple audio card.

2022-04-14ASoC: soc-card: Create jack kcontrol without pinsAkihiko Odaki1-3/+2
snd_soc_card_jack_new() allowed to create jack kcontrol without pins, but did not create kcontrols. The jack would not have kcontrols if pins were not going to be added. This renames the old snd_soc_card_jack_new() to snd_soc_card_jack_new_pins() for use when pins are provided or will be added later. The new snd_soc_card_jack_new() appropriately creates a jack for use without pins and adds a kcontrol.

2022-03-11ASoC: simple-card-utils: Don't reset clock of active DAISameer Pujar1-4/+8
Playback or capture errors are seen when clock is reset during an active stage of DAI. Presently this scenario happens when DAI has both playback and capture sessions running and one of these finishes first which will be followed by clock rate reset. The remaining active session will be affected in such case. Address this problem by allowing clock rate reset to happen only when the DAI is no more active.

2022-03-07ASoC: audio_graph_card2: Add support for variable slot widthsRichard Fitzgerald1-0/+97
Some audio hardware cannot support the same slot width for all sample widths, or a slot width equal to the sample width for all sample widths. This is usually due either to limitations of the audio serial port or system clocking restrictions. A typical example would be: - 16-bit samples in 16-bit slots - 24-bit samples in 32-bit slots The new dai-tdm-slot-width-map property allows setting a mapping of sample widths and the corresponding tdm slot widths and slot counts. Although the slot count is usually the same for all cases this does allow for adding padding slots to maintain the same bitclk frequency. The property is added to each endpoint node that needs the component DAI to be told the TDM slot width and count.

2022-01-24ASoC: simple-card-utils: Add new system-clock-fixed flagRobert Hancock1-11/+60
Add a new system-clock-fixed flag, which can be used to specify that the driver cannot or should not allow the clock frequency of the mapped clock to be modified. This behavior is also implied if the system-clock-frequency parameter is set explicitly - the flag is meant for cases where a clock is mapped to the DAI but which is, or should be treated as, fixed. When mclk-fs is also specified, this causes a PCM constraint to be added which enforces that only the corresponding valid sample rate can be used.

2022-01-24ASoC: simple-card-utils: Set sysclk on all componentsRobert Hancock1-0/+15
If an mclk-fs value was provided in the device tree configuration, the calculated MCLK was fed into the downstream codec DAI and CPU DAI, however set_sysclk was not being called on the platform device. Some platform devices such as the Xilinx Audio Formatter need to know the MCLK as well. Call snd_soc_component_set_sysclk on each component in the stream to set the proper sysclk value in addition to the existing call of snd_soc_dai_set_sysclk on the codec DAI and CPU DAI. This may end up resulting in redundant calls if one of the snd_soc_dai_set_sysclk calls ends up calling snd_soc_component_set_sysclk itself, but that isn't expected to cause any significant harm.

ALSA: control - add generic LED API This patchset tries to resolve the diversity in the audio LED control among the ALSA drivers. A new control layer registration is introduced which allows to run additional operations on top of the elementary ALSA sound controls. A new control access group (three bits in the access flags) was introduced to carry the LED group information for the sound controls. The low-level sound drivers can just mark those controls using this access group. This information is not exported to the user space, but user space can manage the LED sound control associations through sysfs (last patch) per Mark's request. It makes things fully configurable in the kernel and user space (UCM). The actual state ('route') evaluation is really easy (the minimal value check for all channels / controls / cards). If there's more complicated logic for a given hardware, the card driver may eventually export a new read-only sound control for the LED group and do the logic itself. The new LED trigger control code is completely separated and possibly optional (there's no symbol dependency). The full code separation allows eventually to move this LED trigger control to the user space in future. Actually it replaces the already present functionality in the kernel space (HDA drivers) and allows a quick adoption for the recent hardware (ASoC codecs including SoundWire). snd_ctl_led 24576 0 The sound driver implementation is really easy: 1) call snd_ctl_led_request() when control LED layer should be automatically activated / it calls module_request("snd-ctl-led") on demand / 2) mark all related kcontrols with SNDRV_CTL_ELEM_ACCESS_SPK_LED or SNDRV_CTL_ELEM_ACCESS_MIC_LED Link: https://lore.kernel.org/r/20210317172945.842280-1-perex@perex.cz Signed-off-by: Takashi Iwai <tiwai@suse.de>

For now, we assume there is only one or a small set of valid PCM stream parameters, so num_params == 1 is good enough. We also assume that the same params are valid for all supported streams. params is set to the subset of parameters common among all DAIs, and then the existing code automatically chooses the highest quality of the remaining values when the link is brought up.

2019-09-09SoC: simple-card-utils: set 0Hz to sysclk when shutdownKatsuhiro Suzuki1-0/+7
This patch set 0Hz to sysclk when shutdown the card. Some codecs set rate constraints that derives from sysclk. This mechanism works correctly if machine drivers give fixed frequency. But simple-audio and audio-graph card set variable clock rate if 'mclk-fs' property exists. In this case, rate constraints will go bad scenario. For example a codec accepts three limited rates (mclk / 256, mclk / 384, mclk / 512). Bad scenario as follows (mclk-fs = 256): - Initialize sysclk by correct value (Ex. 12.288MHz) - Codec set constraints of PCM rate by sysclk 48kHz (1/256), 32kHz (1/384), 24kHz (1/512) - Play 48kHz sound, it's acceptable - Sysclk is not changed - Play 32kHz sound, it's acceptable - Set sysclk to 8.192MHz (= fs * mclk-fs = 32k * 256) - Codec set constraints of PCM rate by sysclk 32kHz (1/256), 21.33kHz (1/384), 16kHz (1/512) - Play 48kHz again, but it's NOT acceptable because constraints do not allow 48kHz So codecs treat 0Hz sysclk as signal of applying no constraints to avoid this problem.

2019-07-10ASoC: simple-card-utils: care no Platform for DPCMKuninori Morimoto1-0/+7
commit 34614739988ad ("ASoC: soc-core: support dai_link with platforms_num != 1") supports multi Platform, and commit 9f3eb91753451 ("ASoC: simple-card-utils: consider CPU-Platform possibility") removed no Platform from simple-card. Multi Platform is now checking both Platform name/of_node are NULL case. But in normal case, DPCM be doesn't have Platform. asoc_simple_canonicalize_platform() try to use CPU of_node to Platform (This is needed for DMAEngine platform case), but it still might be NULL at DPCM be. This patch try to use no Platform after that if Platform of_node is still NULL. It can't probe without this patch.

2019-06-28ASoC: simple-card-utils: consider CPU-Platform possibilityKuninori Morimoto1-12/+3
commit 6f0437445735 ("ASoC: simple-card-utils: don't select unnecessary Platform") Current ALSA SoC avoid to add duplicate component to rtd, and this driver was selecting CPU component as Platform component. Thus, above patch removed Platform settings from this driver, because it assumed these are same component. But, some CPU driver is using generic DMAEngine, in such case, both CPU component and Platform component will have same of_node/name. In other words, there are some components which are different but have same of_node/name. In such case, Card driver definitely need to select Platform even though it is same as CPU. It is depends on CPU driver, but is difficult to know it from Card driver. This patch reverts above patch.
