Yeah I think this is how we did it for omap3-sbc-*.dts*. > This works but seems, well, verbose.

Hmm I wonder if the "[PATCH] dtc: parser: Add label while overriding nodes" would help with this too? I agree it would be nice to be able to have device specific .dtsi file that can be included multiple times for the most common devices.
