[PATCH v3 1/7] dt-bindings: net: Add generic Bluetooth controller

Sven Peter
2022-09-19T16:49:41Z

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@svenpeter.dev>

changes from v2:
- added new bluetooth subdirectory and moved files there
- removed minItems from local-bd-address
- dropped bjorn.andersson@linaro.org, bgodavar@codeaurora.org and
rjliao@codeaurora.org due to bouncing emails from the CC list

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