No problem as such from my point of view, but this is the process I follow
since maintainer trees for device-tree file and bindings are different. I
generally mark a [DO NOT MERGE] tag for device-tree file patches until binding
patch gets merged so that the device-tree patches don't get applied by mistake
if binding patch has some pending comments.

Once binding patch gets merged, I re-send the device-tree file patches again
to respective list.

Regards
Devarsh
