In general to avoid the huge hassle of cross tree dependencies and
confusion if the dts changes are fixes, I suggest the following:

1. Nikolaus reposts the dts changes to not say word "fix" in them
   and use "update to use new binding" or something similar to avoid
   patches wrongly getting picked into earlier stable trees

2. Then I can ack the patches as they are just oneliners and
   unlikely to conflict with anything else

Regards,

Tony
