From a5fcd5f59a2658a579533d6774e871aea7ab5e92 Mon Sep 17 00:00:00 2001 From: Stepan Moskovchenko Date: Fri, 12 Nov 2010 19:29:50 -0800 Subject: [PATCH] msm: iommu: Revise GFX3D IOMMU contexts and M2V mappings Based on recommendations from chip designers, optimize the Machine ID to translation context mappings for the 3D core's IOMMU. Remove the the "gfx3d_smmu" context device, as it is no longer needed under the new mapping scheme.
