Yes, fine, I stack them for 3.10 then.

Indeed, at first sight its looks like a nice solution. But I wonder if
we add several nodes in this kind of .dtsi files, we may end up with
mess between APB peripherals and board specific ones like leds, NAND, etc.
Moreover, the plain and full naming of the node makes it identifiable
without doubts, even someone not completely familiar with DT.

I slightly prefer to keep it like this, but I can still change my mind ;-)
