I don't have r8a77470 datasheet, but does it have *extended* Audio DMAC peri peri
address (= 0xec760000) ? If it has, please use it instead of normal address (= 0xec740000).

Please add ssiu.
And then, ssi doesn't need "rxu" and "txu" anymore.
These can be good help for you.

BTW, this patch-set is including SoC only.
Do you have plan to post board support patch after this ?
In other words, did you test these ?
Thank you for your help !!
Best regards
