This patch implements the hdev setup function.
wcnss-bt does not have persistent memory to store
an allocated BD address. The device is therefore
marked as unconfigured if no BD address has been
previously retrieved.
Signed-off-by: Loic Poulain <loic.poulain@xxxxxxxxxx>
---
v2: Set device as unconfigured if default address detected
Add warning if BD addr retrieved from DT
v3: if no addr retrieved from DT, unconditionally set
the invalid BD addr flag.
swap and set bdaddr in the platform probe
v4: Add dt-bindings documentation
split patch in two parts (setup, dt prop)
use local-bd-address name instead of local-mac-address
