First things first, I do not have access to the specs nor the schematics, so a lot of this was done via guess work, looking at the acpi tables, and looking at how a similar device (wcn6750) was added. The 5th revision addresses comments from Luiz about the Bluetooth driver, as well as Konrad's comments on the dts file. The end result is that we do have a working device, but not entirely reliable. Hopefully by getting this out there, people who do have access to the specs or schematics can see where the improvements or fixes need to come. There are a few things that I am not sure why they happen, and don't have the knowledge level to figure out why they happen or debugging it.

The BD Address also seems to be incorrect, and I'm not sure what is going on there either. Testing was done by connecting a Razer Orochi bluetooth mouse, and using it, as well as connecting to and using an H2GO bluetooth speaker and playing audio out via canberra-gtk-play as well as a couple of YouTube videos in a browser. The mouse only seems to work when < 2 ft. from the laptop, and for the speaker, only "A2DP Sink, codec SBC" would provide audio output, and while I could see that data was being sent to the speaker, it wasn't always outputting, and going > 4ft. away, would often disconnect. steev@wintermute:~$ hciconfig -a hci0: Type: Primary Bus: UART BD Address: 00:00:00:00:5A:AD ACL MTU: 1024:8 SCO MTU: 240:4 UP RUNNING PSCAN RX bytes:1492 acl:0 sco:0 events:126 errors:0 TX bytes:128743 acl:0 sco:0 commands:597 errors:0 Features: 0xff 0xfe 0x8f 0xfe 0xd8 0x3f 0x5b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF Link mode: PERIPHERAL ACCEPT Name: 'wintermute' Class: 0x0c010c Service Classes: Rendering, Capturing Device Class: Computer, Laptop HCI Version: (0xc) Revision: 0x0 LMP Version: (0xc) Subversion: 0x46f7 Manufacturer: Qualcomm (29) steev@wintermute:~$ dmesg | grep Razer [ 3089.235440] input: Razer Orochi as /devices/virtual/misc/uhid/0005:1532:0056.0003/input/input11 [ 3089.238580] hid-generic 0005:1532:0056.0003: input,hidraw2: BLUETOOTH HID v0.01 Mouse [Razer Orochi] on 00:00:00:00:5a:ad steev@wintermute:~$ dmesg | grep H2GO [ 3140.959947] input: H2GO Speaker (AVRCP) as /devices/virtual/input/input12 Bjorn Andersson (1): arm64: dts: qcom: sc8280xp: Define uart2 Steev Klimaszewski (3): dt-bindings: net: Add WCN6855 Bluetooth Bluetooth: hci_qca: Add support for QTI Bluetooth chip wcn6855 arm64: dts: qcom: thinkpad-x13s: Add bluetooth .../net/bluetooth/qualcomm-bluetooth.yaml | 17 +++++ .../qcom/sc8280xp-lenovo-thinkpad-x13s.dts | 76 +++++++++++++++++++ arch/arm64/boot/dts/qcom/sc8280xp.dtsi | 14 ++++ drivers/bluetooth/btqca.c | 9 ++- drivers/bluetooth/btqca.h | 10 +++ drivers/bluetooth/hci_qca.c | 50 +++++++++--- 6 files changed, 163 insertions(+), 13 deletions(-) base-commit: 4fafd96910add124586b549ad005dcd179de8a18
