[Fabio Porcedda <fabio.porcedda@gmail.com>]

Hi all,
this patchset add the timeout-sec property to the watchdog core,
to the at91sam9_wdt driver and on all framework enabled watchdog driver
with dt support.
The at91sam9_wdt is tested on evk-pr3,
the other drivers are compile tested only.

Best regards
Fabio Porcedda
