I would like to use the integrated wifi device of the i.MX8MQ EVK under linux. Afterthe boot I can see the the PCI device:

root@imx8mqevk:~# lspci -s 01:00.0 -v
01:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
Flags: bus master, fast devsel, latency 0, IRQ 265
Memory at 18000000 (64-bit, non-prefetchable) [size=2M]
Capabilities: [40] Power Management version 3
Capabilities: [50] MSI: Enable- Count=1/8 Maskable+ 64bit-

Capabilities: [180] L1 PM Substates
Kernel driver in use: hif_pci
Kernel modules: wlan

But there is no corresponding interface and iw can't detect any wifi device.

What can be wrong with my system?

Regards

Philippe
