Hello Richard,

Why derived boards couldn't label nodes by themselves? That's what all
derived boards are doing already.

BTW, upstream should benefit from the submitted changes. This is not a
very useful change for upstream if you're not updating the actual DTs of
any of the boards in arch/arm/boot/dts/*.
