Yes, you're right. The simple answer is that I couldn't come up with a good
name for the combined module, since "arm-smmu" is already taken by the core
part of the driver and I don't want to rename that file. Looking at what a
few other drivers do, it seems that "arm-smmu-mod" might be the best bet
so I'll incorporate that change for v2 and put you on cc.

Thanks!

Will
