From ee86a03a5dc64899edb39fe1ce21429fed98d107 Mon Sep 17 00:00:00 2001 From: Timothy Myers Date: Mon, 6 Jul 2020 16:33:31 +0000 Subject: watchdog: booke_wdt: Add common nowayout parameter driver Add the common "nowayout" parameter to booke_wdt to make this behavior selectable at runtime and to make the implementation more consistent with many other watchdog drivers.
