Hi all,
This patch series adds watchdog timer support for the Renesas R-Car V4M
(R8A779H0) Soc and the Gray Hawk Single development board.
I intend to queue this in renesas-devel for v6.9.
Thanks for your comments!

Changes compared to the BSP:
- Split in separate commits for SoC and board support,
- Use TABs for indentation,
- Add missing interrupts property.
