Thanks! I'll interpret your response as:
1. Keep this as two patches and it's more important to keep dts and bindings separate than it is to avoid breaking bisectability of "make dtbs_check".
2. Bindings should have been patch #1, but it's not a massive deal.
3. I'll assume that Bjorn will yell if he'd like this series re-posted with the reverse order.
