Subject: [PATCH 1/2] ARM: dts: armada-xp: add interrupts for watchdog
Date: Fri, 11 Feb 2022 13:32:56 +1300	[thread overview]
Message-ID: <20220211003257.2037332-2-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20220211003257.2037332-1-chris.packham@alliedtelesis.co.nz>

The first interrupt is for the regular watchdog timeout. Normally the
RSTOUT line will trigger a reset before this interrupt fires but on
systems with a non-standard reset it may still trigger.

The second interrupt is for a timer1 which is used as a pre-timeout for
the watchdog.
