Subject: [PATCH v3 1/7] dt-bindings: net: Add generic Bluetooth controller
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@...npeter.dev>
---
changes from v2:
- added new bluetooth subdirectory and moved files there
- removed minItems from local-bd-address
- dropped bjorn.andersson@...aro.org, bgodavar@...eaurora.org and
rjliao@...eaurora.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
