We made this change to configure the device which supports persistent

Can you say something more about which devices support persistent
storage for the address? Is that all or just some of the chip variants?

Most of the devices support persistent storage, and bd-address storage
is chosen based on the OEM and Target.

So to make device functional in both scenarios we are adding a new
property in dts file to distinguish persistent and non-persistent
support of BD Address and set HCI_QUIRK_USE_BDADDR_PROPERTY bit

Depending on the answer to my questions above, you may be able to infer
this from the compatible string and/or you can read out the address from
the device and only set the quirk if it's set to the default address.

You should not need to add a new property for this.


As per my understanding, altering the compatible string may cause duplicate
configuration, right ?
