When you send your next series, can you please split the stuff based on
their dependencies or at least note here what depends on what ? I mean,
I cannot take the DT patches without an Acked-by Grant and Tony, but the
drivers themselves I could take queue them since they're already in good
shape ;-)

Maybe just start the series with patches without dependencies on one
another, and the rest of the series would be ones that need to go
together, or something. That'll help me ;-)
