Subject: [PATCH v3 05/15] ARM: at91: watchdog: implement at91_wdt_disable
Date: Mon,  1 Apr 2019 12:18:13 +0200	[thread overview]
Message-ID: <20190401101822.7392-6-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20190401101822.7392-1-a.fatoum@pengutronix.de>

Low level init code might want to disable the watchdog in PBL.
Provide a helper to do so.
