From 98e089c8b7b4b851d231826d7c814b20a969cde3 Mon Sep 17 00:00:00 2001 From: Vivek Gautam Date: Tue, 4 Dec 2018 11:52:13 +0530 Subject: iommu/arm-smmu: Add support for qcom,smmu-v2 variant [ Upstream commit 89cddc563743cb1e0068867ac97013b2a5bf86aa ] qcom,smmu-v2 is an arm,smmu-v2 implementation with specific clock and power requirements. On msm8996, multiple cores, viz. mdss, video, etc. use this smmu. On sdm845, this smmu is used with gpu. Add bindings for the same.
