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 ↵Kuninori Morimoto1-2/+2
asoc_simple_init_for_codec2codec() 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.

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 Fitzgerald2-0/+101
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.

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.

2022-01-11ASoC: simple-card: fix probe failure on platform componentRobert Hancock1-1/+25
A previous change to simple-card resulted in asoc_simple_parse_dai attempting to retrieve the dai_name for platform components, which are unlikely to have a valid DAI name. This caused simple-card to fail to probe when using the xlnx_formatter_pcm as the platform component, since it does not register any DAI components. Since the dai_name is not used for platform components, just skip trying to retrieve it for those.

2021-10-15ASoC: add Audio Graph Card2 driverKuninori Morimoto3-0/+680
We already have audio-graph-card which is Of-graph base of general sound card driver. It is supporting DPCM connection, but was forcibly expanded. Thus, it is very difficult to add new features on it, for example Multi CPU/Codec support, Codec2Codec support, etc. This patch adds more flexible new Audio Graph Card2 driver for it. audio-graph-card and audio-graph-card2 are similar, but don't have full compatibility. Audio Graph Card2 supports very generic connection, but some users want to have its own settings, for example PLL settings, etc. For such case, it has customizing support. In users own driver, it can use Audio Graph Card2 parsing by using audio_graph2_parse_of(), and doing its own customizing. Because Audio Graph Card2 is still under experimental stage, it will indicate such warning when probing, and the DT syntax might be changed.

2021-10-15ASoC: test-component: add Test Component for Sound debug/testKuninori Morimoto3-0/+667
We already have dummy-codec, dummy-platform. But its issues are 1) we don't have dummy-cpu, 2) we can't select it via DeviceTree 3) It do nothing Sometimes we want to have Dummy Sound Component for debugging, for testing, for learning Framework behavior, etc, etc... This patch adds Test-Component driver for it. User can select CPU Component by using "test-cpu" compatible, and can select Codec Component by using "test-codec" compatible. It doesn't support Platform so far, but is easy to add. We can verbose print to know its progress if user selected xxx-verbose compatible driver. for example, test-cpu : silent Component, silent DAI test-cpu-verbose-component : verbose Component, silent DAI test-cpu-verbose-dai : silent Component, verbose DAI test-cpu-verbose : verbose Component, verbose DAI Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/877dein8rx.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
2021-09-20ASoC: audio-graph: Fixup CPU endpoint hw_params in a BE<->BE linkSameer Pujar1-1/+3
When multiple components are connected back to back in an audio path, hw_param fixup may be required for CPU or Codec endpoint of BE<->BE DAI links. Currently fixup support is available for Codec and this commit adds similar feature for CPU endpoint of a BE<->BE link. For example a resampler component can be plugged into an audio path. [ FE -> BE1 -> ... -> resampler -> ... BEn ] The resampler DAI links can be: BEx (CPU) -> resampler input (Codec) resampler output (CPU) -> BEy (Codec) Thus input and output sample rate parameters for resampler can be fixed up as per the resample requirement.

2021-09-01ASoC: audio-graph: respawn Platform SupportKuninori Morimoto1-0/+6
commit 63f2f9cceb09f8 ("ASoC: audio-graph: remove Platform support") removed Platform support from audio-graph, because it doesn't have "plat" support on DT (simple-card has). But, Platform support is needed if user is using snd_dmaengine_pcm_register() which adds generic DMA as Platform. And this Platform dev is using CPU dev. Without this patch, at least STM32MP15 audio sound card is no more functional (v5.13 or later). This patch respawn Platform Support on audio-graph again.
