From ff25ff842ea6afd58ccc2e3f386ee5ac540b6a63 Mon Sep 17 00:00:00 2001 From: Stepan Moskovchenko Date: Fri, 12 Nov 2010 19:29:51 -0800 Subject: msm: iommu: Revise GFX2D0 IOMMU contexts and M2V mappings Based on recommendations from chip designers, optimize the Machine ID to translation context mappings for the first 2D core's IOMMU. Remove the "gfx2d0_texv3_smmu" context, as it is no longer needed under the new mapping scheme.
