If this interrupter is triggered, that means system has goes wrong, who knows what is wrong , I have to make sure that system get into that routine ,because of the WS0, if not I won't do panic.
But the interrupt handler is not registered as shared, which means that it cannot be generated by another device.
And in a interrupter routine , checking the Interrupter status register is right way to do.
If you get an interrupt, but WS0 is not set, then you should return IRQ_NONE instead of IRQ_HANDLED.
Also, I don't think IRQF_TIMER is correct. It's not a timer interrupt. Watchdogs are *not* timers.
