CPU DAI和codec DAI 驱动用结构体 struct snd_soc_dai_driver描述,其字段ops的类型是 struct snd_soc_dai_ops,定义了DAI驱动的操作接口。 代码如下: struct snd_soc_dai_ops {/* * DAI clocking configuration, all optional. * Called by soc_card drivers, normally in their hw_params. ...
最后,我们需要将snd_soc_dapm_route注册到ASoC平台,以便音频数据能够经过正确的路由传输。 ```c static int my_card_probe(struct platform_device *pdev) { // 注册音频DAI片段 snd_soc_register_dai(&pdev->dev, &my_dai); // 注册snd_soc_dapm_route ...

I don't see snd_soc_bind_card actually calling soc_find_component directly, but it does get called from soc_bind_aux_dev, which is called soon after snd_soc_dapm_init. Essentially, from this call graph, I can see that soc_bind_aux_dev is failing. This hints that this line in my ...
