Documentation: watchdog: at91sam9_wdt: add clocks property
The watchdog has an input clock, the slow clock. It is required as it will not function without it. Reviewed-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
