This isn't a P4080DS. Your board needs its own toplevel compatible.

We need a proper device tree binding for this stuff first.

Please use fsl/p4080si-post.dtsi rather than duplicating all of this.
You appear to have based this on an old SDK kernel, rather than the
current mainline kernel.

"1 10 0 0" and "1 11 0 0" don't look like valid MPIC interrupt specifiers
to me, though. Maybe that's the problem? Is it supposed to be:
<10 1 0 0 11 1 0 0>
?

Are overlapping partitions allowed?
Plus, unit addresses are supposed to match reg.

Where does "fsl,msi" come from?
