Hi Sebastian

Just for my understanding: Is the problem here:

	/* Clear watchdog timer interrupt */
	reg = readl(BRIDGE_CAUSE);
	reg &= ~WDT_INT_REQ;
	writel(reg, BRIDGE_CAUSE);

I ask, because there is no need to pass an interrupt in the DT node.

It is clear to me that bit of code above needs cleaning up sometime
soon.

	Thanks
