Subject: [PATCH v3 1/7] dt-bindings: net: Add generic Bluetooth controller
Date:   Mon, 19 Sep 2022 18:48:28 +0200
Message-Id: <20220919164834.62739-2-sven@svenpeter.dev>

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
