Subject: [PATCH v3 3/3] ARM: dts: r7s72100: Add watchdog timer
Date: Wed,  1 Mar 2017 17:54:55 -0500	[thread overview]
Message-ID: <20170301225455.22818-4-chris.brandt@renesas.com> (raw)
In-Reply-To: <20170301225455.22818-1-chris.brandt-zM6kxYcvzFBBDgjK7y7TUQ@public.gmane.org>

Add watchdog timer support for RZ/A1.
For the RZ/A1, the only way to do a reset is to overflow the WDT, so this
is useful even if you don't need the watchdog functionality.
