I'd like to make a v3 and change the license of the .yaml file to "(GPL-2.0-
only OR BSD-2-Clause)" as suggested by checkpatch and [1].  Can I keep your 
Acked-by for that?

Besides: those suggestions are obviously valid for new bindings.  What about 
old bindings (.txt), which had no explicit SPDX tag or license note before?  
What license would apply there?  Is the .yaml file technically new, when it 
was mostly just converted from .txt?
