But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can swtcih 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/pxa/pxa-ssp.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/sound/soc/pxa/pxa-ssp.c b/sound/soc/pxa/pxa-ssp.c index f37ea0f..e615aca 100644 --- a/sound/soc/pxa/pxa-ssp.c +++ b/sound/soc/pxa/pxa-ssp.c @@ -133,12 +133,12 @@ static void pxa_ssp_shutdown(struct snd_pcm_substream *substream, #ifdef CONFIG_PM -static int pxa_ssp_suspend(struct snd_soc_dai *cpu_dai) +static int pxa_ssp_suspend(struct snd_soc_component *component) { - struct ssp_priv *priv = snd_soc_dai_get_drvdata(cpu_dai); + struct ssp_priv *priv = snd_soc_component_get_drvdata(component); struct ssp_device *ssp = priv->ssp; - if (!cpu_dai->active) + if (!component->active) clk_prepare_enable(ssp->clk); priv->cr0 = __raw_readl(ssp->mmio_base + SSCR0); @@ -151,9 +151,9 @@ static int pxa_ssp_suspend(struct snd_soc_dai *cpu_dai) return 0; } -static int pxa_ssp_resume(struct snd_soc_dai *cpu_dai) +static int pxa_ssp_resume(struct snd_soc_component *component) { - struct ssp_priv *priv = snd_soc_dai_get_drvdata(cpu_dai); + struct ssp_priv *priv = snd_soc_component_get_drvdata(component); struct ssp_device *ssp = priv->ssp; uint32_t sssr = SSSR_ROR | SSSR_TUR | SSSR_BCE; @@ -165,7 +165,7 @@ static int pxa_ssp_resume(struct snd_soc_dai *cpu_dai) __raw_writel(priv->to, ssp->mmio_base + SSTO); __raw_writel(priv->psp, ssp->mmio_base + SSPSP); - if (cpu_dai->active) + if (component->active) pxa_ssp_enable(ssp); else clk_disable_unprepare(ssp->clk); @@ -850,8 +850,6 @@ static const struct snd_soc_dai_ops pxa_ssp_dai_ops = { static struct snd_soc_dai_driver pxa_ssp_dai = { .probe = pxa_ssp_probe, .remove = pxa_ssp_remove, - .suspend = pxa_ssp_suspend, - .resume = pxa_ssp_resume, .playback = { .channels_min = 1, .channels_max = 8, @@ -879,6 +877,8 @@ static const struct snd_soc_component_driver pxa_ssp_component = { .trigger = pxa2xx_soc_pcm_trigger, .pointer = pxa2xx_soc_pcm_pointer, .mmap = pxa2xx_soc_pcm_mmap, + .suspend = pxa_ssp_suspend, + .resume = pxa_ssp_resume, }; #ifdef CONFIG_OF
