Subject: [PATCH v2 5/5] arm64: tegra: Add SMMU nodes to Tegra194 device tree
From: Krishna Reddy <vdumpa () nvidia ! com>

Message-ID: 1541029716-14353-6-git-send-email-vdumpa () nvidia ! com
[Download RAW message or body]
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.
