In dw_wdt_open() we were calling it with a value that's supposed to represent the maximum value programmed into the "top" register with a comment saying that we were trying to set the watchdog to its maximum value. Instead we ended up setting the watchdog to ~15 seconds. Let's fix this. However, setting things to the "max" gives me an 86 second watchdog in the system I'm looking at. 86 seconds feels a little too long. We'll explicitly choose 30 seconds as a more reasonable value. NOTE: Ideally this driver should be transitioned to be a real watchdog driver. Then we could use "watchdog_init_timeout" and let the timeout be specified in a number of ways (device tree, module parameter, etc). This patch should be considered a bit of a stopgap solution.
