[alsa-devel] About the platform_name field in snd_soc_dai_link

Hi,

I'm wondering what exactly a snd_soc_platform is. Apparently the snd_pcm_ops/pcm_new/pcm_free are specific to a platform. For my understanding these operations are more specific to a cpu_dai. Looking at the tree it seems that each cpu_dai has exactly one possible platform, which seems logical to me because the cpu_dai knows how to transfer the data.

My problem on i.MX is that I currently have two possible cpu dais (imx-ssi.[01]) and each can be configured to use dma or fiq depending on the dma capabilities. So the cpu_dai knows which pcm_ops we have to use, but currently it's the soc glue code which has to decide in platform_name. Am I understanding something wrong here?
