[PATCH v2 1/5] dt-bindings: net: Add generic Bluetooth controller

[Sven Peter]

Bluetooth controllers share the common local-bd-address property.
Add a generic YAML schema to replace bluetooth.txt for those.

Signed-off-by: Sven Peter <sven@xxxxxxxxxxxxx>

changes from v1:
  - removed blueetooth.txt instead of just replacing it with a
    deprecation note
  - replaced references to bluetooth.txt

checkpatch complains here because it thinks I do to many things at once,
I think it's better to replace bluetooth.txt in single commit though.
Let me know if you prefer this to be split into multiple commits
instead.
