Subject: [PATCH v2 1/3] ARM: dts: armada-38x: add interrupts for watchdog
Date: Wed,  6 Mar 2019 09:19:22 +1300	[thread overview]
Message-ID: <20190305201924.14853-2-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20190305201924.14853-1-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.

- new, split out from "watchdog: orion_wdt: use timer1 as a pretimeout"
