This is the 4th version of the patchset, which started out as a bit of an
RFC/RFT but has actually worked so, I think this 4th revision is in a pretty
decent spot, at least in terms of the code itself... that said...
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.
This 4th revision does have the regulators added, which were pulled from the
bsrc_bt.bin file from the Windows partition.
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 SOC Version :0x400c0210
Bluetooth: hci0: QCA ROM Version :0x00000201
Bluetooth: hci0: QCA Patch Version:0x000038e6
Bluetooth: hci0: QCA controller version 0x02100201
Bluetooth: hci0: unexpected event for opcode 0xfc48
Bluetooth: hci0: Sending QCA Patch config failed (-110)
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.
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.

I suspect the above message is not really needed since you didn't even
request the firmware at this point.

This is really ugly I must say, why don't we just check if
qcadev->init_speed has been set then we set it as hu->init_speed?

Since it appears there is already a struct like this for each soc type
we could perhaps just extend with the data needed instead of checking
the soc_type over and over again.

Not sure if this newline is necessary.

Hi Luiz and all:
I am QC bt host guys, today I sync up with qc btfw team and conclude following result:
1: as I mentioned before, qca2066 and wcn6855 are the same chip family, and they can share the same btfw patch, and distinguish by using different nvm based on board id.
2: I upload the btfw previously for qca2066 , you can refer to https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=2ba1beaae0c649ce8a50baecc8df9e81cd524e65 , and also wcn6855 can share to use btfw patch and nvm with qca2066.
3:steev patch does not include read board id part logical , I think it is better combine the steev patch and my patch into one.
Regards.
Tim

Could you please review Steev changes, also if you could please refactor the code regarding the soc_type, making the necessary field as part of the data structure should make it a lot easier to add support for new configurations without having to change the code in multiple places.
