Thank you! I just committed this to HEAD, minus the patch for the dts.

We try not to directly patch upstream dts files because they are difficult 
to merge. What we've been doing now is overriding on a per-board basis 
using a dts with the same name in sys/arch/arm/dts (not ideal but that's 
where we are today).

You can take sys/arch/arm/dts/sun8i-h3-nanopi-neo.dts as an example. It 
does a few things:

1) include the original upstream dts file as a starting point
2) include a soc specific dtsi that defines devices found on the SoC
3) finally, it enables any optional components and configures board 
specific parameters

HTH,
Jared
