Add device nodes for the Serial Communication Interfaces with FIFO
(SCIF) on the Renesas R-Car V4M (R8A779H0) SoC, including DMA support.
Based on a patch in the BSP by Nghia Nguyen.
Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
---
Changes compared to the BSP:
- Change reg size from 0x64 to 64,
- Change "scif_clk2" to "scif_clk" in clock-names for SCIF4,
- Add DMA properies.
