Subject: [PATCH v3 5/6] arm64: dts: marvell: add interrupt support to ap806 thermal node
Date: Tue,  4 Dec 2018 20:03:31 +0100	[thread overview]
Message-ID: <20181204190332.10351-6-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20181204190332.10351-1-miquel.raynal@bootlin.com>

Add interrupt properties in the thermal node as well as a critical trip
point in the thermal-zone.
