[PATCH v3 0/3] DT binding for sample format conversion
by Sameer Pujar 15 Aug '22

15 Aug '22

DT binding properties are available to fixup rate and channel parameters of a DAI. This series extends this to sample format conversion as well. With this now DAI PCM parameters (channels, sample rate and sample format) can be fixed up as necessary in an audio path. Changelog: ========== v2->v3: ------- * Fix DT binding errors in simple-card.yaml * Drop simple-card binding changes from the series since there is no usage requirement. It can be extended later when necessary. * Use definitions instead of properties in the common schema and re-use this in audio-graph related bindings. v1->v2: ------- * Move DAI params properties to a new schema and re-use this for simple-card and audio-graph-card. * Use string type for DAI format binding as suggested by Krzysztof.

[PATCH v4] ASoC: dt-bindings: fsl,sai: Convert format to json-schema
by Shengjiu Wang 15 Aug '22

15 Aug '22

Convert the NXP SAI binding to DT schema format using json-schema. The Synchronous Audio Interface (SAI) provides an interface that supports full-duplex serial interfaces with frame synchronization formats such as I2S, AC97, TDM, and codec/DSP interfaces. Beside conversion, 'fsl,shared-interrupt' and '#sound-dai-cells' are added for they are already used by some dts.

[PATCH v3] ASoC: Intel: cirrus-common: Use UID to map correct amp to prefix
by Stefan Binding 15 Aug '22

15 Aug '22

Since the order of the amps in the ACPI determines the device name, and the ACPI order may change depending on hardware configuration, use UID to dynamically compute the dai links, allowing dynamic assignment of the name_prefix. The UIDs for these amps in ACPI are fixed, and map to a name_prefix, where: UID 0x0 -> WL UID 0x1 -> WR UID 0x2 -> TL UID 0x3 -> TR Signed-off-by: Stefan Binding <sbinding(a)opensource.cirrus.com> Signed-off-by: Vitaly Rodionov <vitalyr(a)opensource.cirrus.com> --- sound/soc/intel/boards/sof_cirrus_common.c | 92 ++++++++++++---------- 1 file changed, 49 insertions(+), 43 deletions(-) diff --git a/sound/soc/intel/boards/sof_cirrus_common.c b/sound/soc/intel/boards/sof_cirrus_common.c index f4192df962d6..6e39eda77385 100644 --- a/sound/soc/intel/boards/sof_cirrus_common.c +++ b/sound/soc/intel/boards/sof_cirrus_common.c @@ -10,6 +10,9 @@ #include "../../codecs/cs35l41.h" #include "sof_cirrus_common.h" +#define CS35L41_HID "CSC3541" +#define CS35L41_MAX_AMPS 4 + /* * Cirrus Logic CS35L41/CS35L53 */ @@ -35,50 +38,12 @@ static const struct snd_soc_dapm_route cs35l41_dapm_routes[] = { {"TR Spk", NULL, "TR SPK"}, }; -static struct snd_soc_dai_link_component cs35l41_components[] = { - { - .name = CS35L41_DEV0_NAME, - .dai_name = CS35L41_CODEC_DAI, - }, - { - .name = CS35L41_DEV1_NAME, - .dai_name = CS35L41_CODEC_DAI, - }, - { - .name = CS35L41_DEV2_NAME, - .dai_name = CS35L41_CODEC_DAI, - }, - { - .name = CS35L41_DEV3_NAME, - .dai_name = CS35L41_CODEC_DAI, - }, -}; +static struct snd_soc_dai_link_component cs35l41_components[CS35L41_MAX_AMPS]; /* * Mapping between ACPI instance id and speaker position. - * - * Four speakers: - * 0: Tweeter left, 1: Woofer left - * 2: Tweeter right, 3: Woofer right */ -static struct snd_soc_codec_conf cs35l41_codec_conf[] = { - { - .dlc = COMP_CODEC_CONF(CS35L41_DEV0_NAME), - .name_prefix = "TL", - }, - { - .dlc = COMP_CODEC_CONF(CS35L41_DEV1_NAME), - .name_prefix = "WL", - }, - { - .dlc = COMP_CODEC_CONF(CS35L41_DEV2_NAME), - .name_prefix = "TR", - }, - { - .dlc = COMP_CODEC_CONF(CS35L41_DEV3_NAME), - .name_prefix = "WR", - }, -}; +static struct snd_soc_codec_conf cs35l41_codec_conf[CS35L41_MAX_AMPS]; static int cs35l41_init(struct snd_soc_pcm_runtime *rtd) { @@ -117,10 +82,10 @@ static int cs35l41_init(struct snd_soc_pcm_runtime *rtd) static const struct { unsigned int rx[2]; } cs35l41_channel_map[] = { - {.rx = {0, 1}}, /* TL */ {.rx = {0, 1}}, /* WL */ - {.rx = {1, 0}}, /* TR */ {.rx = {1, 0}}, /* WR */ + {.rx = {0, 1}}, /* TL */ + {.rx = {1, 0}}, /* TR */ }; static int cs35l41_hw_params(struct snd_pcm_substream *substream, @@ -175,10 +140,51 @@ static const struct snd_soc_ops cs35l41_ops = { .hw_params = cs35l41_hw_params, }; +static const char * const cs35l41_name_prefixes[] = { "WL", "WR", "TL", "TR" }; + +/* + * Expected UIDs are integers (stored as strings). + * UID Mapping is fixed: + * UID 0x0 -> WL + * UID 0x1 -> WR + * UID 0x2 -> TL + * UID 0x3 -> TR + * Note: If there are less than 4 Amps, UIDs still map to WL/WR/TL/TR.

[PATCH] ASoC: imx-rpmsg: Support configure sysclk for codec dai
by Shengjiu Wang 15 Aug '22

Some codecs need to configure the sysclk even with slave mode, otherwise it may not work properly with some case. wm8960 is the one that need sysclk be configured, so add late_probe() to call the snd_soc_dai_set_sysclk() of codec Signed-off-by: Shengjiu Wang <shengjiu.wang(a)nxp.com> --- sound/soc/fsl/imx-rpmsg.c | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) diff --git a/sound/soc/fsl/imx-rpmsg.c b/sound/soc/fsl/imx-rpmsg.c index 2e117311e582..bef4bd997c98 100644 --- a/sound/soc/fsl/imx-rpmsg.c +++ b/sound/soc/fsl/imx-rpmsg.c @@ -19,6 +19,7 @@ struct imx_rpmsg { struct snd_soc_dai_link dai; struct snd_soc_card card; + unsigned int sysclk; }; static const struct snd_soc_dapm_widget imx_rpmsg_dapm_widgets[] = { @@ -28,6 +29,27 @@ static const struct snd_soc_dapm_widget imx_rpmsg_dapm_widgets[] = { SND_SOC_DAPM_MIC("Main MIC", NULL), }; +static int imx_rpmsg_late_probe(struct snd_soc_card *card) +{ + struct imx_rpmsg *data = snd_soc_card_get_drvdata(card); + struct snd_soc_pcm_runtime *rtd = list_first_entry(&card->rtd_list, + struct snd_soc_pcm_runtime, list); + struct snd_soc_dai *codec_dai = asoc_rtd_to_codec(rtd, 0); + struct device *dev = card->dev; + int ret; + + if (!data->sysclk) + return 0; + + ret = snd_soc_dai_set_sysclk(codec_dai, 0, data->sysclk, SND_SOC_CLOCK_IN); + if (ret && ret != -ENOTSUPP) { + dev_err(dev, "failed to set sysclk in %s\n", __func__); + return ret; + } + + return 0; +} + static int imx_rpmsg_probe(struct platform_device *pdev) { struct snd_soc_dai_link_component *dlc; @@ -72,12 +94,18 @@ static int imx_rpmsg_probe(struct platform_device *pdev) data->dai.codecs->dai_name = "snd-soc-dummy-dai"; data->dai.codecs->name = "snd-soc-dummy"; } else { + struct clk *clk; + data->dai.codecs->of_node = args.np; ret = snd_soc_get_dai_name(&args, &data->dai.codecs->dai_name); if (ret) { dev_err(&pdev->dev, "Unable to get codec_dai_name\n"); goto fail; } + + clk = devm_get_clk_from_child(&pdev->dev, args.np, NULL); + if (!IS_ERR(clk)) + data->sysclk = clk_get_rate(clk); } data->dai.cpus->dai_name = dev_name(&rpmsg_pdev->dev); @@ -103,6 +131,7 @@ static int imx_rpmsg_probe(struct platform_device *pdev) data->card.owner = THIS_MODULE; data->card.dapm_widgets = imx_rpmsg_dapm_widgets; data->card.num_dapm_widgets = ARRAY_SIZE(imx_rpmsg_dapm_widgets); + data->card.late_probe = imx_rpmsg_late_probe; /* * Inoder to use common api to get card name and audio routing. * Use parent of_node for this device, revert it after finishing using -- 2.34.1
