From 774dfc9bb7f2ab1950a790a8f13eca3d5c580033 Mon Sep 17 00:00:00 2001 From: Hiroshi DOYU Date: Thu, 10 May 2012 10:45:32 +0300 Subject: iommu/tegra: gart: Fix register offset correctly DT passes the exact GART register ranges without any overlapping with MC register ranges. GART register offset needs to be adjusted by one passed by DT correctly.
