Subject: [PATCH v3 6/6] arm64: tegra: Add SMMU nodes to Tegra194 device tree
Date: Mon, 3 Dec 2018 17:36:54 -0800	[thread overview]
Message-ID: <1543887414-18209-7-git-send-email-vdumpa@nvidia.com> (raw)
In-Reply-To: <1543887414-18209-1-git-send-email-vdumpa@nvidia.com>

Add SMMU nodes and dma-ranges to Tegra194 device tree.
Tegra194 has three ARM SMMU Instances. Two of them are used
together to access IOVA interleaved. The third one is used
as regular ARM SMMU.
