For this, the new version uses 8 (4 * 2) input and -output pins, with each pin being responsible for 2 channels. This sums up -to a total of 8 channels for synchronous capture and playback. - -Signed-off-by: Codrin Ciubotariu <codrin.ciubotariu@microchip.com> -Link: https://lore.kernel.org/r/20210301170905.835091-4-codrin.ciubotariu@microchip.com -Signed-off-by: Mark Brown <broonie@kernel.org> ---- - sound/soc/atmel/mchp-i2s-mcc.c | 38 ++++++++++++++++++++++++++++++++++ - 1 file changed, 38 insertions(+) - ---- a/sound/soc/atmel/mchp-i2s-mcc.c -+++ b/sound/soc/atmel/mchp-i2s-mcc.c -@@ -16,6 +16,7 @@ - #include <linux/clk.h> - #include <linux/mfd/syscon.h> - #include <linux/lcm.h> -+#include <linux/of_device.h> - - #include <sound/core.h> - #include <sound/pcm.h> -@@ -225,6 +226,10 @@ static const struct regmap_config mchp_i - .max_register = MCHP_I2SMCC_VERSION, - }; - -+struct mchp_i2s_mcc_soc_data { -+ unsigned int data_pin_pair_num; -+}; -+ - struct mchp_i2s_mcc_dev { - struct wait_queue_head wq_txrdy; - struct wait_queue_head wq_rxrdy; -@@ -232,6 +237,7 @@ struct mchp_i2s_mcc_dev { - struct regmap *regmap; - struct clk *pclk; - struct clk *gclk; -+ const struct mchp_i2s_mcc_soc_data *soc; - struct snd_dmaengine_dai_dma_data playback; - struct snd_dmaengine_dai_dma_data capture; - unsigned int fmt; -@@ -549,6 +555,17 @@ static int mchp_i2s_mcc_hw_params(struct - } - - if (dev->fmt & (SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_LEFT_J)) { -+ /* for I2S and LEFT_J one pin is needed for every 2 channels */ -+ if (channels > dev->soc->data_pin_pair_num * 2) { -+ dev_err(dev->dev, -+ "unsupported number of audio channels: %d\n", -+ channels); -+ return -EINVAL; -+ } -+ -+ /* enable for interleaved format */ -+ mrb |= MCHP_I2SMCC_MRB_CRAMODE_REGULAR; -+ - switch (channels) { - case 1: - if (is_playback) -@@ -558,6 +575,12 @@ static int mchp_i2s_mcc_hw_params(struct - break; - case 2: - break; -+ case 4: -+ mra |= MCHP_I2SMCC_MRA_WIRECFG_I2S_2_TDM_1; -+ break; -+ case 8: -+ mra |= MCHP_I2SMCC_MRA_WIRECFG_I2S_4_TDM_2; -+ break; - default: - dev_err(dev->dev, "unsupported number of audio channels\n"); - return -EINVAL; -@@ -869,12 +892,22 @@ static const struct snd_soc_component_dr - }; - - #ifdef CONFIG_OF -+static struct mchp_i2s_mcc_soc_data mchp_i2s_mcc_sam9x60 = { -+ .data_pin_pair_num = 1, -+}; -+ -+static struct mchp_i2s_mcc_soc_data mchp_i2s_mcc_sama7g5 = { -+ .data_pin_pair_num = 4, -+}; -+ - static const struct of_device_id mchp_i2s_mcc_dt_ids[] = { - { - .compatible = "microchip,sam9x60-i2smcc", -+ .data = &mchp_i2s_mcc_sam9x60, - }, - { - .compatible = "microchip,sama7g5-i2smcc", -+ .data = &mchp_i2s_mcc_sama7g5, - }, - { /* sentinel */ } - }; -@@ -932,6 +965,11 @@ static int mchp_i2s_mcc_probe(struct pla - dev->gclk = NULL; - } - -+ dev->soc = of_device_get_match_data(&pdev->dev); -+ if (!dev->soc) { -+ dev_err(&pdev->dev, "failed to get soc data\n"); -+ return -ENODEV; -+ } - dev->dev = &pdev->dev; - dev->regmap = regmap; - platform_set_drvdata(pdev, dev); |
