This is my attempt to make ath11k work on IPQ9574. IPQ9574 is intended
for wifi-7 devices, so it seems the exception rather than the rule to
pair it with a wifi-6 chip. That's exactly what my Archer BE550 does.
This consists of a wifi-6 (QCN5024) chip connected via PCIe to the
SoC, but exposed to the OS via AHB. The Q6 firmware [4] requires
remoteproc support introduced in a separate series [3]. The QMI
firmware interface is very similar to IPQ6018, such that almost no
new code is needed.
I am not including the wifi@c000000 devicetree node in this series, as
it depends on nodes from the remoteproc series [3].
I have been successfully doogfooding this for a few of weeks in AP mode.
There dependencies to this series. [2] is a compile-time dependency,
whereas [1] and [3] are needed for full functionality. I was adivsed to
leave [1] and [2] as separate patches and not add them to this series.
