uart9 is debug serial on USB SBU1/2

UART RX is SBU1 and UART TX is SBU2 of the USB-C port).
1.8V Logic Level
Tested using pololu usb07a https://www.pololu.com/product/2585
and CH340 USB-UART

uart6 is bluetooth

Bluetooth: hci0: setting up wcn399x
Bluetooth: hci0: QCA Product ID   :0x0000000a
Bluetooth: hci0: QCA SOC Version  :0x40010214
Bluetooth: hci0: QCA ROM Version  :0x00000201
Bluetooth: hci0: QCA Patch Version:0x00000001
Bluetooth: hci0: QCA controller version 0x02140201
Bluetooth: hci0: QCA Downloading qca/crbtfw21.tlv
Bluetooth: hci0: QCA Downloading qca/judyln/crnv21.bin
Bluetooth: hci0: QCA setup on UART is completed
