Hi Shengjiu Cc Mark Thank you for the patch > This reverts commit 33683cbf49b5412061cb1e4c876063fdef86def4. > > dai_link->platform is needed.

I understood the issue. Can I ask 2 things ? My original patch removed 3 platforms. Then, I understood that 2 of them are used as soc-generic-dmaengine-pcm (= 1st, 3rd platform). I think we want to have comment here that why dummy component is needed. Can you agree ? I wonder how about 2nd platform ? Is it same ? I'm asking because it doesn't have of_node which other 2 platforms have. Thank you for your help !! Best regards --- Kuninori Morimoto
