Blech. Oh well. Not much point in doing something different if x86
uses a void*.
x86 probably does this because two different implementations needs to
plug their private data there: intel-iommu plugs there a

Will that meet your needs?
It's almost there, but not entirely.
Benoit's alloc/delete functions focus on the
will now work on OMAP without
utilizing any omap-specific API.
The changes are tested on OMAP3 (with omap3isp) and OMAP4 (with
remoteproc/rpmsg).
This is still RFC (2nd patch is probably the least elegant).

(the downside is reduced typesafety).
Note: ia64, x86 and sparc have this exact iommu extension as well, and
if others are likely to adopt it too, we might want to consider
adding this to the device struct itself directly.

Bind OMAP3's isp device to the isp's dedicated iommu, by setting
the device's archdata iommu member.
This way omap3isp will be able to use the generic IOMMU API without
having to call any omap-specific binding method.

Let the IOMMU core know we support 4KiB, 64KiB, 1MiB and 16MiB page sizes.
This way the IOMMU core can split any arbitrary-sized physically
