* gpu: nvgpu: add platform specific get_iova_addr()Deepak Nibade2015-04-04
| | | | | | | | | | | | | | | | | | Add platform specific API pointer (*get_iova_addr)() which can be used to get iova/physical address from given scatterlist and flags Use this API with g->ops.mm.get_iova_addr() instead of calling API gk20a_mm_iova_addr() which makes it platform specific Bug 1605653 Change-Id: I798763db1501bd0b16e84daab68f6093a83caac2 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/713089 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
