* watchdog: Add Renesas RZ/N1 Watchdog driverPhil Edworthy2022-05-211-0/+203
This is a driver for the standard WDT on the RZ/N1 devices. This WDT has very limited timeout capabilities. However, it can reset the device. To do so, the corresponding bits in the SysCtrl RSTEN register need to be enabled. This is not done by this driver.
