This patchset is somewhat of an RFC/RFT, and also just something to get this out
there.
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.
There are definitely checkpatch warnings, and I do apologize to those who won't
review things until there are no warnings for wasting your time.
One example is that I have the vregs commented out, the dt-bindings say that
they are required since it's based on the wcn6750 work but also like the 6750,
I've added defaults into the driver, and those seem to work, at least for the
initial testing.
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.
Bluetooth: hci0: setting up wcn6855
Bluetooth: hci0: Frame reassembly failed (-84)
Bluetooth: hci0: QCA Product ID :0x00000013

Bluetooth: hci0: QCA Downloading qca/hpbtfw21.tlv
Bluetooth: hci0: QCA Downloading qca/hpnv21g.bin
Bluetooth: hci0: QCA setup on UART is completed
I do not know why the Frame assembly failed, nor the unexpected event.
Likewise, I'm not entirely sure why it says the patch config send times out, and
*then* seems to send it?
The BD Address also seems to be incorrect, and I'm not sure what is going on
there either.
Additionally, I've tried with an additional patch that I'm not including that is
based on commit 059924fdf6c1 ("Bluetooth: btqca: Use NVM files based on SoC ID
for WCN3991") to try using the hpnv21g.bin or hpnv21.bin, and the firmware acted
the same regardless, so I am assuming I don't truly need the "g" firmware on my
Thinkpad X13s.
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.

Thank you for the patches. Reading until the end and seeing patch 4/4,
this is related to the Lenovo Thinkpad X13s. I am adding Mark Pearson to
the Cc list. No idea if GNU/Linux is officially supported by Lenovo, but
even if not, maybe Mark is able to get you access to the specifications
and schematics.
Kind regards,
Paul

You should also add your Signed-off-by. Also the title of the patch
should be updated to say define uart2 instead of enable BT.

This node needs to go after spi2 instead of spi3.
Everything else looks good to me.

Proper threading is all patches are reply to cover letter.
Drop the last 'binding' in the subject. Don't need it twice.

Sorry, I'm not sure what happened with my threading here, I changed
chainreplyto=true to false in my .gitconfig so hopefully v2 will come
correctly.
