Based on SP805 Programmer's model (ARM DDI 0270B). This driver
provides three public APIs:
void sp805_start(uintptr_t base, unsigned long ticks);
void sp805_stop(uintptr_t base);
void sp805_refresh(uintptr_t base, unsigned long ticks);
Upon start, the watchdog starts counting down from the number of
ticks specified. When the count reaches 0 an interrupt is triggered.
The watchdog restarts counting down from the number of ticks
specified. If the count reaches 0 again, the system is reset. A
mechanism to handle the interrupt has not been implemented. Instead,
the API to refresh the watchdog should be used instead to prevent a
system reset.
