Subject: [PATCH] Bluetooth: hci_sync: Add fallback-bd-address prop
|
|
|
|
The kernel Bluetooth framework understands that devices may not
|
|
be programmed with valid Bluetooth addresses. It also has the ability
|
|
to override a Bluetooth address with the value of the local-bd-address
|
|
DT property, but it ignores the validity of the existing address when
|
|
doing so.
|
|
|
|
Add a new boolean property, fallback-bd-address, which indicates that
|
|
the given local-bd-address property should only be used if the device
|
|
does not already have a valid BDADDR.
