Thank you for your help
I have sent 2 patches as [RFC]
	[RFC] dmaengine: rcar-audmapp: calculate chcr via src/dst addr
	[RFC] ARM: shmobile: r8a7790: sound enables Audio DMAC peri peri entry on DTSI

Actually, sound driver side needs fixup patch related to these change.
But above are focusing to Audio DMAC peri peri at this point.
Main change is 2/2 patch, it is using 22 node on this patch.
(it needed 220 node without theses patches)

Best regards
