Should 0x400. This parameter is the size, not the end address.

Please remove the interrupt-parent. It is not needed since DT will use
the parent node to get it. It will avoid duplicating the entry for every
nodes.

Can you just add a comment to give more information. I know this is in
the binding documentation, but some more comment never hurt.

0x400 as well.

Ditto.
