Depends whether the device is mounted via SDIO or PCI. Only PCI
devices are supported by ath10k.

The other possible problem is there might be extra tinkering required
to boot/start the device. I suspect there might be an extra GPIO or
two for WiFi reset. And then there's Android which may have been
modified by the vendor to somehow suit the proprietary QCA6174 driver
so ath10k might not work out of the box.
