[PATCH 1/2] Bluetooth: btqca: Introduce generic QCA ROME support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is for supporting BT for QCA ROME with specific vendor
specific HCI commands and initialization. This will have USB/UART
implementation both, but for now, adding UART vendor specific
commands to patch downloading and set BDaddress using VS command.
