From ef20061a34e0e6822cbfd20c11667ae23a96798d Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 20 Jan 2020 10:04:37 +0900 Subject: ASoC: dwc: dwc-i2s: move .suspend/.resume to component There is no big difference at implementation for .suspend/.resume between DAI driver and Component driver. 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 Link: https://lore.kernel.org/r/87y2u3x7iy.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown --- sound/soc/dwc/dwc-i2s.c | 32 ++++++++++++++++++-------------- 1 file changed, 18 insertions(+), 14 deletions(-) (limited to 'sound') diff --git a/sound/soc/dwc/dwc-i2s.c b/sound/soc/dwc/dwc-i2s.c index 65112b9d8588..7eeca2150b2d 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); -- cgit v1.2.3-59-g8ed1b
