But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC. Driver is getting its private data via dai->dev. But dai->dev and component->dev are same dev, thus, we can convert these. For same reason, we can convert dai->active to component->active if necessary. This patch moves DAI driver .suspend/.resume to Component driver Signed-off-by: Kuninori Morimoto --- sound/soc/dwc/dwc-i2s.c | 32 ++++++++++++++++++-------------- 1 file changed, 18 insertions(+), 14 deletions(-) diff --git a/sound/soc/dwc/dwc-i2s.c b/sound/soc/dwc/dwc-i2s.c index 65112b9..7eeca21 100644 --- a/sound/soc/dwc/dwc-i2s.c +++ b/sound/soc/dwc/dwc-i2s.c @@ -390,10 +390,6 @@ static const struct snd_soc_dai_ops dw_i2s_dai_ops = { .set_fmt = dw_i2s_set_fmt, }; -static const struct snd_soc_component_driver dw_i2s_component = { - .name = "dw-i2s", -}; - #ifdef CONFIG_PM static int dw_i2s_runtime_suspend(struct device *dev) { @@ -413,26 +409,30 @@ static int dw_i2s_runtime_resume(struct device *dev) return 0; } -static int dw_i2s_suspend(struct snd_soc_dai *dai) +static int dw_i2s_suspend(struct snd_soc_component *component) { - struct dw_i2s_dev *dev = snd_soc_dai_get_drvdata(dai); + struct dw_i2s_dev *dev = snd_soc_component_get_drvdata(component); if (dev->capability & DW_I2S_MASTER) clk_disable(dev->clk); return 0; } -static int dw_i2s_resume(struct snd_soc_dai *dai) +static int dw_i2s_resume(struct snd_soc_component *component) { - struct dw_i2s_dev *dev = snd_soc_dai_get_drvdata(dai); + struct dw_i2s_dev *dev = snd_soc_component_get_drvdata(component); + struct snd_soc_dai *dai; if (dev->capability & DW_I2S_MASTER) clk_enable(dev->clk); - if (dai->playback_active) - dw_i2s_config(dev, SNDRV_PCM_STREAM_PLAYBACK); - if (dai->capture_active) - dw_i2s_config(dev, SNDRV_PCM_STREAM_CAPTURE); + for_each_component_dais(component, dai) { + if (dai->playback_active) + dw_i2s_config(dev, SNDRV_PCM_STREAM_PLAYBACK); + if (dai->capture_active) + dw_i2s_config(dev, SNDRV_PCM_STREAM_CAPTURE); + } + return 0; } @@ -441,6 +441,12 @@ static int dw_i2s_resume(struct snd_soc_dai *dai) #define dw_i2s_resume NULL #endif +static const struct snd_soc_component_driver dw_i2s_component = { + .name = "dw-i2s", + .suspend = dw_i2s_suspend, + .resume = dw_i2s_resume, +}; + /* * The following tables allow a direct lookup of various parameters * defined in the I2S block's configuration in terms of sound system @@ -629,8 +635,6 @@ static int dw_i2s_probe(struct platform_device *pdev) return -ENOMEM; dw_i2s_dai->ops = &dw_i2s_dai_ops; - dw_i2s_dai->suspend = dw_i2s_suspend; - dw_i2s_dai->resume = dw_i2s_resume; res = platform_get_resource(pdev, IORESOURCE_MEM, 0); dev->i2s_base = devm_ioremap_resource(&pdev->dev, res);
