Handling System MMUs with an identifier is not flexible to manage
System MMU platform devices because of the following reasons:
1. A device driver which needs to handle System MMU must know the ID.
2. A System MMU may not present in some implementations of Exynos family.
3. Handling System MMU with IOMMU API does not require an ID.
This patch is the result of removing ID of System MMUs.
Instead, a device driver that needs to handle its System MMU must
use IOMMU API while its descriptor of platform device is given.
This patch also includes the following enhancements:
- A System MMU device becomes a child if its power domain device.
- clkdev

This patch doesn't apply cleanly against upstream Linux (v3.3-rcX).
Please rebase to upstream and resend. The other 2 patches apply fine.
Yes, as KyoungHo said, this has been created on top of Samsung tree
for-next because this touches many exynos stuff which has been changed
from Samsung tree for upcoming merge window. So if you're ok on this,
1st patch and this should be sent to upstream via samsung tree even
though I can't find any topic branch for this yet. And if you want topic
branch for your tree, let me know, I can provide it.
Thanks.
Best regards,
Kgene.
