[PATCH 0/3] watchdog: at91sam9_wdt: various fixes and improvements

[Boris BREZILLON]

Hello,

This patch series fix the secs_to_ticks macro in case 0 is passed as an
argument.

It also rework the heartbeat calculation to increase the security margin of the
watchdog reset timer, and use the min_heartbeat value instead of the calculated
heartbeat value for the first watchdog reset (to avoid spurious watchdog
reset).

Best Regards,

Boris
