[PATCH 0/4] Cleanup legacy OMAP IOMMU device creation

Hi Tony,
The following series removes the legacy platform device creation
logic for OMAP IOMMU devices. I will cleanup the legacy support
from the OMAP IOMMU driver in a subsequent merge window after
this series makes it to mainline.
Patches are based on 4.3-rc1 + the OMAP3 ISP instantiation cleanup
patch [1]. All the patches need to be picked up sequentially,
otherwise a NULL pointer dereference crash might be seen on OMAP3
legacy boots as the dev attribute structure is deferenced directly
in mach-omap2/omap-iommu.c during platform data creation. Also, the
last patch removes the structure definition altogether, so will
cause build issues if picked separately from the hwmod cleanup
patches.
I do not have any boards where I can still perform a legacy-style
boot, so patches verified using DT-boot only.
regards
Suman
