This is duplicated from scif0, and should be:

        dmas = <&dmac0 0x2d>, <&dmac0 0x2e>;

> +               dma-names = "tx", "rx";

After

        sed -i -e 's/7791/779x/g' arch/arm/boot/dts/r8a7791.dtsi
        sed -i -e 's/7793/779x/g' arch/arm/boot/dts/r8a7793.dtsi

arch/arm/boot/dts/r8a7791.dtsi and arch/arm/boot/dts/r8a7793.dtsi should
be identical ;-)

Gr{oetje,eeting}s,

                        Geert

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
