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.
v2->v3:
- Fixed commit header for the patches rzv2h_wdt->rzv2h
- Added reviewed-by from Wolfram
- Merged "watchdog: rzv2h_wdt: Make reset controller optional"
patch with "watchdog: rzv2h: Make "oscclk" and reset controller optional"
- Dropped patch "watchdog: rzv2h: Set min_timeout based on
max_hw_heartbeat_ms" instead updated the period for RZ/T2H.
- Updated rzv2h_of_data structure to include tops and timeout_cycles
for RZ/T2H.
v1->v2:
- Dropped items from clock-names and instead added maxItems: 1.
- Added reviewed-by from Rob.
Cheers,
Prabhakar
