[PATCH v6 3/5] watchdog: at91sam9_wdt: add device tree support

I was thinking to add a more generic helper function like this:

static inline void watchdog_get_dttimeout(struct device_node *node,
u32 *timeout)
{
	if (node)
		of_property_read_u32(node, "timeout", &wdd->timeout);
}

You forgot to change the function signature. 

Also, if you are adding a generic function, it should be a generic
function for the framework. All drivers should be slowly moving
towards the framework, so adding functions which help you not move
towards the framework are wrong.
