This series adds support for the IPA subsystem found in the SM8450 SoC.
While IPA v5.0 is very similar to IPA v5.1 (heck, it even managed to
properly get the modem up and running), it wasn't perfect, since the
modem would sometimes hang when rebooting or powering the AP off.
After a thorough investigation, I managed to create the proper data file
required for IPA v5.1.

I assume you have implemented this based on what you found in
some downstream code. And if so, could you please indicate
where to find that (so I can do some cross-referencing myself).
I no longer have access to any Qualcomm internal documentation.
Thanks.
