From 63c7ecd7b10778157f7c84367e1535f4c023d828 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Fri, 2 Oct 2015 18:23:25 -0500 Subject: [PATCH] ARM: dts: DRA74x: Add IOMMU nodes for DSP2 The DRA74x family of SoCs have a second DSP, that also has two MMUs just like the DSP1 subsystem. Add the IOMMU nodes for this DSP2 subsystem in disabled state to the DRA74x specific DTS file, the nodes would need to be enabled appropriately in the respective board DTS files.
