Subject: [PATCH 0/4] Add support for QCA9379 hw1.0 SDIO WiFi/BT

Add support for Qualcomm QCA9379-3 SDIO based adapters.

The Bluetooth part is straightforward. It simply adds a DT compatible
string to the existing driver.

The WiFi part is a followup to the RFC I sent back in February [0], that
didn't receive any comments.

Since then I aligned the patch closer to what the driver does for the
QCA6174 rather than the QCA9377, as the latter hasn't been touched in a
while.
With that the driver no longer throws errors for non-existent calibration
data.

The roaming and group re-keying issues still persist, but may not be
specific to this chipset, as this (or a similar issue) is apparently seen
on other chipsets as well [1].
The user impact of this issue is an intermittent loss of connectivity
while the adapter re-associates. Other than that the connection is
stable.

I have tested this patch on a Lenovo ThinkSmart View (CD-18781Y) that
comes with a LITEON WCBN3510A module. The firmware and boardfile used for
testing was pulled from the original Android image. A file at
/modem/verinfo/ver_info.txt on the Android image identifies the WiFi
part as "WLAN.NPL.1.6-00163-QCANPLSWPZ-1" and the Bluetooth part as
"BTFM.NPL.1.0.4-00002-QCABTFMSWPZ-1".

No firmware files are currently available from public repositories, but
they should available from the vendor website [2] for customers that have
the according access.

I can submit the boardfile to the ath10k list once this patch is
accepted. The one that is included with the Android system image has a
sha256sum of 65767cca6a1ff88a9899235acdeeed1e9447a2f16f41d38052202835d5bda7d4.

If someone from Qualcomm could add both the WiFi and BT firmwares to the
linux-firmware repositories that would be much appreciated.
I'm happy to test any firmware before submission, if desired.

Thanks,
Felix
