This is an odd ordering, mostly because of things like devicetree's are pretty arm/linux centric. In which case if your doing arm/linux just find a module you can unload or fail to build into your kernel. Real embedded programming is more like grab a cortex-m0, avr, etc and start bit banging.

OTOH, there is a danger that I've seen frequently that embedded systems guys don't seem to be able to make the conceptual leap to fully paged, SMP programming. Having sort of come up this way myself (via mircocomputers without MMUs and just a single processor) it doesn't make any sense to me, but it seems common.

People who have been exposed to a more common multi-threaded and virtualized environment seem to be able to pick up those pieces easier.
