[PATCH v2 0/3] iommu: Remove OMAP IOVMM driver

Hello,

The OMAP3 ISP driver was the only user of the OMAP IOVMM API. Now that is has
been ported to the DMA API, remove the unused virtual memory manager.

The removal is split in three patches to ease upstream merge. The first patch
removes the omap-iovmm driver, the second patch removes setting of now unused
platform data fields from arch code, and the last patch cleans up the platform
data structure.

I'd like to get at least the first patch merged in v3.17. To avoid splitting
the series across three kernel versions, it would be nice to also merge at
least the second patch for v3.17. If there's no risk of conflict everything
could be merged in one go through the ARM SoC tree. Otherwise a stable branch
with patch 1/3 will be needed to base the arch change on.

Joerg, Tony, how would you like to proceed ?

Changes compared to v1:

- Fix OMAP_IOMMU_DEBUG dependency on OMAP_IOMMU
- Remove omap_iommu da_start and da_end fields
- Added patches 2/3 and 3/3
