Hi Mark Cc Shengjiu
The driver which is using soc-generic-dmaengine-pcm is a little bit difficult to notice about it, because it prepares own Component, but shares same component->dev with CPU Component.
Some fsl driver is using soc-generic-dmaengine-pcm as Platform Component.
When binding CPU/Codec, it finds relevant Component, and checks target DAI. If it it was target DAI, ASoC binds its Component to Card. In Platform case, it finds relevant Component and bind it. It doesn't check DAI. This means, we can share CPU dlc with Platform in this case. It is more reasonable / understandable / intuitive.
This patch-set share CPU dlc with Platform, and adds such comment.
Because I can't test this patch-set, thus I added [RFC] on Subject. Please test these. This patch-set requests Tested-by.
