There's no need for this to be in the commit message.

The interrupt property is fairly ubiqutous. There's not really any
need to document it in this manor.

Use the IRQ includes in dt-bindings.

I'm a bit confused by this. Is it now common practice to break out
nodes in this way? I assume to counter mass indentation, but it's a
bit alien to me.

Are these all board specific, or are they shared with any other
platform?
