From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rob Clark Subject: [PATCH 0/4] iommu: add qcom_iommu for early "B" family devices Date: Thu, 3 Aug 2017 06:47:48 -0400 Message-ID: <20170803104800.18624-1-robdclark@gmail.com> Return-path: Sender: linux-arm-msm-owner@vger.kernel.org To: iommu@lists.linux-foundation.org, linux-arm-msm@vger.kernel.org Cc: Archit Taneja , Rob Herring , Will Deacon , Sricharan , Mark Rutland , Robin Murphy , Rob Clark List-Id: iommu@lists.linux-foundation.org An iommu driver for Qualcomm "B" family devices which do implement the ARM SMMU spec, but not in a way that arm-smmu can support. (I initially added support to arm-smmu, but it was decided that approach was too intrusive and it would be cleaner to have a separate driver.) I should note that all the dependencies for this driver have been merged since 4.12, and it is the last thing needed for having another fully- enabled (gpu/display/video codec/etc) ARM device that is fully upstream. One minor change to move a couple #defines and MMU500 bits back to arm-smmu.c as suggested by Will.
