Subject: [PATCH 6/7] arm64: dts: renesas: r8a774b1: Tie SYS-DMAC to IPMMU-DS0/1
Date: Tue, 24 Sep 2019 09:22:54 +0100	[thread overview]
Message-ID: <1569313375-53428-7-git-send-email-biju.das@bp.renesas.com> (raw)
In-Reply-To: <1569313375-53428-1-git-send-email-biju.das@bp.renesas.com>

Hook up r8a774b1 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.
