Subject: [RFC/PATCH 0/3] omap3-iommu: cleanups and remote registration

I think that this part of code is just a simple conventional
platform_device registration and there may be no need to add more
complexicity by introducing a new special structure/function just for
a workaround of a client module("tidspbridge"). Also having these
device registrations here and there doesn't look so nice, looking at
other ones around kernel.

Fixing tidspbridge itself is the way to go, and it seems that Hari has
already verified this iommu with tidspbridge and he's pointed out some
of missing features(*1). I hope that tidspbridge will start to use
iommu soon.
