According to user reference manual for R-CAR H3, M3-W and M3-N SoCs,
in order to access busif4 ~ busif7, extended audio dmac registers
(PDMASAREn, PDMADAREn, PDMACHCREn)
need to be used, rather than basic audio dmac registers
(PDMASARn, PDMADARn, PDMACHCRn)
Now DT bindings has stated that extended Audio dmac register set need
to be used when available with patch
https://patchwork.kernel.org/patch/10856905/
This patch set updates H3 (= r8a7795), M3-W (= r8a7796) and M3-N (=r8a77965)
to use extended audio dmac register set.
---
v4: use a single patch to update
v3: update H3 (= r8a7795), M3-W (= r8a7796) and M3-N (=r8a77965) to point
point to extended audio dmac register set in DT
v2: update rsnd driver to use extended register set when available
rename R-CAR E3 audio dmac regisetr
v1: initial version
