The driver is compatible with AST2400 and AST2500 watchdogs. There is no uclass for Watchdog yet, so the driver does not follow the driver model. It also uses fixed clock, so no clock driver is needed.

This should come from DT. I suggest creating a simple uclass for the watchdog timer, so you can make this a proper driver-model driver.
