Optional properties:
- interrupts : Should specify WDT interrupt number.
+- timeout-sec : Should specify default WDT timeout in seconds. If unset, the
+ default timeout is 30 seconds
According to the SP805 TRM, the default interval is dependent on the
rate of WDOGCLK, but would typically be a lot longer than that :/
On a related note, anyone have any idea why we seem to have two subtly
different SP805 bindings defined?
