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") Signed-off-by: Eugeniu Rosca <erosca@de.adit-jv.com> --- arch/arm64/boot/dts/renesas/r8a7795.dtsi | 3 --- 1 file changed, 3 deletions(-)
