Subject: [PATCH 1/2] ARM: Layerscape: Be less noisy when no iommu node found
Date: Tue, 24 Mar 2020 14:16:19 +0100	[thread overview]
Message-ID: <20200324131620.10864-1-s.hauer@pengutronix.de> (raw)

The IOMMU node is not present in the upstream dts files. Do not complain
too loudly when we are presented such a device tree.
