From 0ac4f03f62ce17ce96bab06d7b22bafc3c6f28f1 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Wed, 5 Mar 2014 18:24:12 -0600 Subject: [PATCH] ARM: OMAP2+: change the ISP device archdata MMU name for DT The IOMMU DT adaptation support uses the device name instead of an iommu object name. Fixup the ISP device archdata MMU name at runtime if using DT-boot. This allows the OMAP3 camera to be functional in both legacy and DT boots. The iommu object names should eventually vanish when all the IOMMU users have been converted to DT nodes.
