Looks alright, the same story here with the DT. I updated to v3, with
the prospect of updating this later in the cycle when needed.

I dropped the Ethernet support from the defconfig for now, as I moved
the EMAC driver fixes out of this initial series. Ideally we can still
get them merged next week.
