Subject: arm64: dts: renesas: r8a774a1: Tie SYS-DMAC to IPMMU-DS0/1
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c3362a74d977f2509b5523afddc9887b3831279f;p=openwrt%2Fstaging%2Fblogic.git

arm64: dts: renesas: r8a774a1: Tie SYS-DMAC to IPMMU-DS0/1

Hook up r8a774a1 DMAC nodes to the IPMMUs. In particular SYS-DMAC0
gets tied to IPMMU-DS0, and SYS-DMAC1 and SYS-DMAC2 get tied to IPMMU-DS1.

Based on work for the r8a7796 by Magnus Damm.
