As mentioned in the cover letter, this is a bit closer to an RFC than ready to go in, and I do apologize that it wasn't clear enough. I do not have access to the schematics, and based on my reading of the schema for bluetooth, these entries are supposed to be required, however, like the wcn6750, I have dummy data entered into the qca_soc_data_wcn6855 struct. I know that these should be there, I just do not have access to the correct information to put, if that makes sense? <snip> >Does not look like you tested the DTS against bindings.

Well you don't have the RFC set in the subject which is probably why people are reviewing it like it is supposed to be merged, that said I do wonder if there is to indicate these entries are to be considered sort of experimental so we don't end up enabling it by default? > > <snip> > > >Does not look like you tested the DTS against bindings.
