Subject: [PATCH 3/6] arm64: dts: renesas: r8a7795: zap dma configuration in scif2
Date:   Sat,  4 May 2019 02:42:55 +0200

Both empirically and based on the existing documentation, it looks like
SCIF2 does not support DMA. Let's disable it. Full reasoning is given in
commit ("Revert "arm64: dts: renesas: r8a7796: Enable DMA for SCIF2"").

Fixes: eb21089c32054e ("arm64: dts: renesas: r8a7795: Add missing SYS-DMAC2 dmas")
Fixes: 49af46b4095672 ("arm64: renesas: r8a7795: Add all SCIF nodes")
