Thanks for your patch!

Reviewed-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
i.e. will queue in renesas-fixes for v7.0.

Apparently the same applies to RZ/V2N.  Shall I just apply this patch
to arch/arm64/boot/dts/renesas/r9a09g056.dtsi, too, with the SoC name
and part numbers updated, and

    Fixes: 7db958983c8dd14d ("arm64: dts: renesas: r9a09g056: Add
WDT0-WDT3 nodes")

?
