Here it comes: From d210b4c540bc4adcebd51d5a87437d2049649e94 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Thu, 22 Jun 2017 21:20:54 +0200 Subject: [PATCH] iommu/arm-smmu-v3, acpi: Add temporary Cavium SMMU-V3 IORT model number definitions The model number is already defined in acpica and we are actually waiting for the acpi maintainers to include it: https://github.com/acpica/acpica/commit/d00a4eb86e64 Adding those temporary definitions until the change makes it into include/acpi/actbl2.h. Once that is done this patch can be reverted.
