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/jz4740/jz4740-i2s.c | 18 ++++++++---------- 1 file changed, 8 insertions(+), 10 deletions(-) diff --git a/sound/soc/jz4740/jz4740-i2s.c b/sound/soc/jz4740/jz4740-i2s.c index 38d48d1..9d54058 100644 --- a/sound/soc/jz4740/jz4740-i2s.c +++ b/sound/soc/jz4740/jz4740-i2s.c @@ -324,12 +324,12 @@ static int jz4740_i2s_set_sysclk(struct snd_soc_dai *dai, int clk_id, return ret; } -static int jz4740_i2s_suspend(struct snd_soc_dai *dai) +static int jz4740_i2s_suspend(struct snd_soc_component *component) { - struct jz4740_i2s *i2s = snd_soc_dai_get_drvdata(dai); + struct jz4740_i2s *i2s = snd_soc_component_get_drvdata(component); uint32_t conf; - if (dai->active) { + if (component->active) { conf = jz4740_i2s_read(i2s, JZ_REG_AIC_CONF); conf &= ~JZ_AIC_CONF_ENABLE; jz4740_i2s_write(i2s, JZ_REG_AIC_CONF, conf); @@ -342,9 +342,9 @@ static int jz4740_i2s_suspend(struct snd_soc_dai *dai) return 0; } -static int jz4740_i2s_resume(struct snd_soc_dai *dai) +static int jz4740_i2s_resume(struct snd_soc_component *component) { - struct jz4740_i2s *i2s = snd_soc_dai_get_drvdata(dai); + struct jz4740_i2s *i2s = snd_soc_component_get_drvdata(component); uint32_t conf; int ret; @@ -352,7 +352,7 @@ static int jz4740_i2s_resume(struct snd_soc_dai *dai) if (ret) return ret; - if (dai->active) { + if (component->active) { ret = clk_prepare_enable(i2s->clk_i2s); if (ret) { clk_disable_unprepare(i2s->clk_aic); @@ -455,8 +455,6 @@ static struct snd_soc_dai_driver jz4740_i2s_dai = { }, .symmetric_rates = 1, .ops = &jz4740_i2s_dai_ops, - .suspend = jz4740_i2s_suspend, - .resume = jz4740_i2s_resume, }; static struct snd_soc_dai_driver jz4780_i2s_dai = { @@ -475,12 +473,12 @@ static struct snd_soc_dai_driver jz4780_i2s_dai = { .formats = JZ4740_I2S_FMTS, }, .ops = &jz4740_i2s_dai_ops, - .suspend = jz4740_i2s_suspend, - .resume = jz4740_i2s_resume, }; static const struct snd_soc_component_driver jz4740_i2s_component = { .name = "jz4740-i2s", + .suspend = jz4740_i2s_suspend, + .resume = jz4740_i2s_resume, }; #ifdef CONFIG_OF
