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.
