Hi All,

This patch series adds watchdog driver support for the Renesas RZ/T2H
(R9A09G077) and RZ/N2H (R9A09G087) SoCs. The necessary device tree
bindings and driver modifications are included.

v1->v2:
- Dropped items from clock-names and instead added maxItems: 1.
- Added reviewed-by from Rob.

Cheers,
Prabhakar
