This series is triggered by a regression on M3 targets caused by https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=703db5d1b175 ("arm64: dts: renesas: r8a7796: Enable DMA for SCIF2"), when applied on top of rcar-3.9.x Renesas official kernel. This collection of patches attempts to consistently propagate the fix across the existing R-Car3 DTS. Full story is placed into commit ("Revert "arm64: dts: renesas: r8a7796: Enable DMA for SCIF2""). While debugging drivers/tty/serial/sh-sci.c, a minor update avoiding __ptrval__ in dev_dbg() is included here as well.
