From mboxrd@z Thu Jan 1 00:00:00 1970 From: robin.murphy@arm.com (Robin Murphy) Date: Mon, 25 Sep 2017 14:55:40 +0100 Subject: [PATCH] iommu/arm-smmu-v3: Correct COHACC override message Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Slightly confusingly, when reporting a mismatch of the ID register value, we still refer to the IORT COHACC override flag as the "dma-coherent property" if we booted with ACPI. Update the message to be firmware-agnostic in line with SMMUv2.
