This patch adds basic device tree definitions for Samsung S3C64xx SoCs.

Since all the SoCs in the series are very similar, the files are created
hierarchically - one file for the whole series and then separate files
for particular SoCs including the common one.

These nodes should be off a "simple-bus" node.

Hmm, is there any reason behind it?

I thought simple bus was just a convenient helper to represent hierarchical 
bus structures if one has a need to do so.

No. The DT should reflect the bus structure of the chip. How
accurately it is done is up to you and the information available, but
you have to have a bus of some sort.

There's obvious examples that don't follow this, but I'd like to not have more.

Please discard this series for now.

I've decided to post it for 3.11, including a driver for Common Clock 
Framework and several cleanup patches, which I have ready and waiting.
