Bluetooth SCO from HCI
 

Hi folks, I'm developing in a nanopc-t4 with 4.4.126 kernel version new features like SCO bluetooth. The schematic show that the BT chip hasn't got the PCM pins chipped, so I'm trying to develop the SCO by the HCI instead of PCM. I have searched a bunch of times about this feature but I only find out a kernel sco driver and some dtb with sco but all of them have a i2s interface. Has anyone know how to configure the dtb to support HCI SCO.
