Add QMI client driver for Q6 integrated WLAN connectivity subsystem.
This module is responsible for communicating WLAN control messages to FW
over QMI interface.
“QUALCOMM Messaging Interface”(QMI) provides the control interface between
components running b/w remote processors with underlying transport layer
based on integrated chipset(shared memory) or discrete chipset(PCI/USB/SDIO/UART).
QMI client driver implementation is based on qmi frmework https://lwn.net/Articles/729924/.
Below is the sequence of qmi handshake.
QMI CLIENT(APPS) QMI SERVER(FW in Q6)
<------wlan service discoverd----
-----connect to wlam qmi service----->
------------wlan info request----->
<------------wlan info resp------------

<------------msa ready indication-------

Can you give an example which chipset series is Q6 integrated WLAN ?
Thanks,

Does the responsibility of the driver ends here? I mean is this a driver
for setting up the firmware and then there's something else doing the
actual wifi operation, or does it simply hand over execution to the
common ath10k logic at this point?

I'm missing this last patch in my mailbox, and it would be nice if all
the patches where in-reply-to the cover letter, to make them easier to
find.

From wlan qmi client point of view once wlan qmi service is discovered,
it connects to the service and
does the above handshakes and later it handover the execution to common
ath10k logic.
These handshakes will be done as part of pd restart as well.

BTW, I noticed that you had v3 only in the cover letter but the version
number should be in every patch part of the set:
