Subject: [PATCH 2/2] iommu/arm-smmu: Plumb in new ACPI identifiers
Date: Fri, 12 May 2017 11:41:42 +0100	[thread overview]
Message-ID: <18776416ca1543f13b85209851b0e5dfab511b06.1494585645.git.robin.murphy@arm.com> (raw)
In-Reply-To: <0bb462748c0a08dbf1db103d2a96b80c71412817.1494585645.git.robin.murphy@arm.com>

Revision C of IORT now allows us to identify ARM MMU-401 and the Cavium
ThunderX implementation; wire them up so that the appropriate quirks get
enabled when booting with ACPI.
