That's a good goal, but difficult to achieve as you can see. Given 
dtbs_check in general has tons of warnings already, we currently don't 
worry about more warnings in specific branches. We just look at mainline 
and linux-next. And for that it's still so many, I'm just looking at 
general trends. It runs daily here[1].

As we get more platforms trying to stay at zero warnings, then we'll 
need to revisit this. I imagine that will mean all schemas have to go in 
1 branch with acks from subsystem maintainers. That's the opposite of 
what we do now. And then .dts branches will have to merge in the schema 
branch as needed. There are some checks (make dt_compatible_check) to 
for drivers vs. the schemas, so we'd have the same issue with 
intermittent warnings. But the drivers should be more decoupled from the 
schemas than the dts files.
